A/N: I had promised myself I wouldn't do a Timeless multichapter fic. I'd sworn to whoever wanted to hear that I didn't have time to commit to something like this, but then the Timeless Writers had to go and post those script pages on Father's Day. And that made me think about how Ethan Cahill was Lucy's only living family member (excluding her horrible biological father), now that Carol was dead and Amy was still gone. I tweeted about that and someone replied, reminding me that Benjamin Cahill actually has a son, who happens to be Lucy's half brother.

And then I had this idea and it just wouldn't leave me alone until I let the words out. So here we are.

Rise Up

i.

Lucy woke up with a start.

The clanking sounds of the new bunker were still so unfamiliar that she found it hard to sleep through them. It had been only a couple of days since Denise had secured them a new facility and they had all moved in under the cover of a moonless night.

Running a hand through the tangle of her hair, she looked around, eyes scanning her new room. It was sparse, just like the other bunker, with only a cot and a small dresser. At least she had the room to herself this time. After their successful trip to save Rufus and moving to their new hiding place, they had all been glad to find that this place had more rooms than their previous bunker, which meant that they could all have their own space.

Never had she been so relieved to have some privacy. It had only been four days since their future counterparts had left and Lucy still couldn't wrap her head around everything that had happened in the past couple of weeks. It all felt too surreal, too traumatic to even begin .

She still couldn't quite believe that Rufus was here with them. Alive. It still took her breath away every time she looked at him. She had seen his lifeless body. She had grieved for him.

She was still grieving for him. Even though he was back, alive and well, she didn't know how to turn that grief off. She couldn't forget everything they had been through. The unfiltered rage she'd felt when she ran after Emma, determined to pump her full of so many holes for every little thing she had done to ruin her life. The blind rage when she pressed the barrel of the gun to the redhead's forehead.

Those brief few minutes played on a loop in her head and she couldn't turn it off, as much as she tried. It was still so fresh, the wounds still gaping open in her soul.

Looking at her phone, she realized it was still early, but decided to get up and get some coffee, anyway. Sleep seemed to elude her these days and she knew she wouldn't be able to fall back asleep now.

Pulling her robe on, she put on her slippers and made her way out of her room. The bunker was still quiet, with the exception of the random clanking sounds that had woken her up. She could hear someone working on the punching bag in the gym room a few doors down from her, and figured it was Wyatt. He was having just as much trouble sleeping as she was, and she often heard him wandering the halls in the middle of the night, or taking out his frustration and grief on that punching bag.

They hadn't talked about his untimely love declaration since all hell had broken loose a few days before. If she was being honest with herself, Lucy didn't know how to respond or even how to feel. Just a few weeks ago, those four little words would have been a dream come true. But now, after everything they'd been through, it felt like someone was squeezing her heart very tight. Every time she tried to think about it, the pressure in her chest returned, so she filed it away for the time being.

Maybe one day she would be ready to process, but her poor heart couldn't handle the stress right now. She needed to glue herself back together first. Then, maybe, she could try and figure out her mess of a love life.

Arriving at the kitchen, she was surprised to see the coffee maker already on and a fresh pot of coffee waiting for her. She wondered if Wyatt had been the one to do it, since he was already up, but when she made it to their common room, Lucy was surprised to find Jiya sitting in front of the computers.

"Hey," she called out, her voice still sounding sleepy and raspy to her own ears. Jiya jumped a foot in the air and turned around, hand on her chest. "Sorry, didn't mean to scare you." She smiled, apologetic, and took a sip of her coffee.

"Jesus, you just shaved ten years off my life, Lucy." The techie grinned at her and nodded to the empty chair next to her.

"What are you doing up so early?" Lucy asked curiously, sitting down next to Jiya. "Did something happen?"

"I just couldn't sleep. Didn't want to bother Rufus. He still feels weird about dying and not remembering." She trailed off, but shook her head after a beat, smiling sheepishly at Lucy. "So I needed to do something productive to keep myself from going crazy."

"Yeah? What are you working on?" She prodded gently, taking another sip of her coffee before leaning back on her chair. She knew Jiya was having a hard time adjusting to life in the bunker after living in the nineteenth century for three years.

"I've set up facial recognition alerts for Emma and Jessica." She said with a shrug. "They haven't jumped in a few days, but that doesn't mean that they're not active here in the present, right?" She explained, looking at Lucy to confirm that she was following. "And I want to catch those bitches so bad, Lucy. They need to pay for everything they've done." The last part was said in a harsh, angry whisper and Lucy reached out, squeezing her friend's hand in comfort.

"Did you find anything?"

"Jessica has been out a couple of times in the past two days. It looks like she's either following someone or scouting a place." Jiya pressed a few keys and an image popped up on the screen. "See? She's been going to this place. I've seen her trying to talk to a kid."

Lucy's eyes widened when she recognized the house.

"Wait. That's…"

"Yup. That's Benjamin Cahill's house." Jiya confirmed her suspicions and Lucy had to take a deep breath, her heart beating wildly in her chest. "And the kid? That's his son, Tyler Cahill. 15 years old."

"He's…" Lucy swallowed, running a hand through her hair. "He's my brother. He's a kid." She closed her eyes and shook her head, trying to process this. "How long have you known about this?"

"I've seen Jessica around the house these past couple of days. But I only saw this footage of her talking to Tyler a few minutes ago. That was last night." Jiya pointed at the screen, enhancing the frozen image. The kid even kind of looked like her. "My best guess is that she's maybe trying to recruit him?"

Lucy stood up, feeling suddenly even more restless than before, as she started to pace.

This was a kid. A 15-year-old boy. It didn't matter that Benjamin Cahill was his father and she thought he was a terrible human being. This kid, Tyler, he was still her little brother. Still just a child. Maybe there was time to save him. Maybe there was still time to stop him from becoming a Rittenhouse monster.

"We can't let that happen, Jiya. We can't." She let out a breath. "I can't. I wouldn't be able to live with myself."

Wyatt threw one last punch to the bag, feeling his arms burning with exertion. He had been at this for over an hour and the sweat rolling down his back and the dull ache in his arms told him it was probably time to stop.

Grabbing a towel, he quickly dried his face and neck and took a sip of water from the bottle he had left by the door. He was thinking that maybe it'd be a good idea to start breakfast for everyone when he heard her voice.

"We can't let that happen, Jiya. We can't. I can't." The distress in her tone made him close the distance between them in record time.

"Hey, what's going on?" He asked, steadying Lucy when she abruptly turned around at the sound of his voice. "Lucy? What's wrong?"

He watched as Lucy and Jiya exchanged a look and how the techie waited until Lucy nodded.

"We found some troubling info on what Jessica has been up to." Jiya started slowly, looking at him with sympathetic eyes and Wyatt felt his stomach sink.

God, he couldn't even fully process that his ex-no-longer-dead wife was a full on Rittenhouse psychopath and she was already out there creating even more shit? He shook his head and took a deep breath.

"What'd she do?" He asked warily and looked from the techie to Lucy, who averted her eyes. He sighed. She could barely look him in the eyes these days. "Jiya."

"She's seeking out Benjamin Cahill's son, apparently." She explained, clicking on something and making a photo pop up on the screen. "He's a kid. Barely 15."

Wyatt looked at the screen, feeling his anger burn in his chest. He couldn't believe he had let himself be so manipulated by her. But then the name Jiya mentioned finally clicked in his brain.

"Wait, Cahill as in…"

"My biological father, yes." Lucy completed for him and met his eyes for the first time. She looked conflicted, but her eyes reflected such a deep sadness, that all he wanted to do was take her in his arms and never let her go. "And that's my little brother. Who is just a kid." She shook her head and ran a hand through her hair agitated. "We can't let them get to him."

"Lucy…" he started, but she shook her head again. "I know that you feel a responsibility to him, but who's to say he isn't Rittenhouse already? You saw what they did to Jess. They started her off young."

It killed him that they had done this to Jessica. Killed him. That they'd done it because of him. They'd gone back in time and plucked her from her family for the sole purpose of messing with him and turn her into the perfect Rittenhouse agent. Someone he would never question. Someone he had loved more than life itself and had tried for so long to bring back.

They were cruel. He understood where Lucy was coming from, but they couldn't risk it. Not after the Jessica fiasco. He would never, ever forgive himself for the domino chain of events he had set in motion the moment he'd received that text and run out of the bunker to go find her. He regretted his actions that day so deeply in his soul and wished more than anything they could just hit the rewind button, so he could ignore that text and just live his life with Lucy. That was all he wanted for the past few months. Forget this madness and just be with his historian.

"I can't not try, Wyatt." Lucy retorted and he closed his eyes, letting out a sigh. "Look at him. He's just a boy. He doesn't deserve to get caught up in this."

"Look, we don't even know if this is what really happened, okay?" Jiya intervened. "How about we talk this out with Agent Christopher when she gets here and see what she says?"

Wyatt was so grateful for Jiya's sensibleness that he could kiss her. He threw a grateful nod in her direction and smiled when she nodded in understanding. Lucy still looked at the screen stubbornly. He could almost see the wheels turning in her head as she stared at the photo of her long lost little brother.

"Jiya's right. We should talk to Agent Christopher first." He told Lucy, reaching out to squeeze her shoulder comfortingly. She didn't shy away like last time, but she didn't allow his hand to linger for too long. "Come on. I'll make us breakfast. What do you feel like eating?"

Lucy offered a small smile that didn't reach her eyes, and shrugged. "Whatever you want to make is fine. I'm not really hungry."

She mumbled something about taking a shower and left, not even giving Wyatt the time to try and talk to her some more. It felt like she was avoiding him and he couldn't exactly blame her. He was the fool who had dumped his love declaration right after they had watched their best friend die. The idiot who brought his back-from-the-dead wife to the bunker and flaunted her in Lucy's face. If he didn't know how to act around her, she was probably feeling even more at a loss about this.

It was his own damn fault. But, God, he missed her so much.

"Are you out of your goddamn mind? No." Agent Christopher's voice was categorically firm. "Have we learned nothing with this whole Jessica thing? No, this is not happening."

"Denise, please. You know I wouldn't even ask something like this if it wasn't important." Lucy pleaded with her, but the Homeland Security agent wasn't having any of it. "He's a teenager. Just a kid."

"I can't authorize this, Lucy. I'm sorry. I really am. But I can't let another Jessica situation happen again. Teenager or not. It's a risk I can't take. And neither can you." Denise touched her shoulder, giving it a sympathetic squeeze. "You have a target the size of China on your back. I can't risk your safety."

Lucy sighed and looked at Wyatt. She knew he agreed with Agent Christopher wholeheartedly. That it was way too risky for someone that they didn't even know was Rittenhouse or not. But the crux of the matter was that this boy, Tyler, he was pretty much all the family she had left. She knew Ethan was still alive, but he was nearing 90. Who knew how long he would still be here. Plus, Tyler was just a kid. She couldn't even reconcile the fact that she might be letting this child just be taken away to be brainwashed by Rittenhouse. She had to do something.

"I promise I'll keep an eye on him, Lucy." Jiya chimed in when she failed to say anything. "If anything fishy happens, I promise you'll be the first to know." She reassured her, and Lucy nodded, but it still wasn't enough.

There was just this feeling, deep in her gut, that made her feel restless. Like a foreboding that she could feel in her soul. She couldn't even really articulate her thoughts into words, but she knew she had to do something for him.

"Thanks, Jiya."

She offered the techie a small smile, also thanking Agent Christopher, before making her way to the couch and plopping herself down. Turning the TV on, she sighed, trying to think. If she was being really honest with herself, she didn't even know how to explain this sudden need to keep this boy she didn't even know safe. Maybe it was because she couldn't save Amy - plus everything that had happened with Rufus - that made her feel like a failure.

But Tyler? There was a tangible, real way to save him from a very dark path, and she felt like she couldn't just sit back and do nothing. If she could help him, she most definitely would. She had already failed one sibling; she'd be damned if she failed the other.

Putting her feet up on the coffee table in front of her, she started to formulate a plan.

Wyatt watched Lucy from afar as he and Agent Christopher went over some files from Nicholas Keynes' old manifesto. The raid he had done at Rittenhouse Headquarters had actually been very productive once Mason and Jiya had managed to sort through everything, and they had now been trying to pinpoint when and where the remaining sleeper agents had been dropped. Keynes' manifesto and the recovered files from their HQ presented a wealth of information for their mission.

But he was distracted. He knew the news about Cahill's kid had hit Lucy hard, especially after everything they'd been through these past few weeks. As far as he knew, the kid was the only family she had left, now that Carol was dead. And he understood why she felt like she had to save the boy, but the risk was far too great. And he'd be damned if he'd let anything happen to her again.

A disturbance from the kitchen made him look away from his historian, only to find Rufus cursing up a storm because he'd cut his finger. He chuckled and shook his head, so incredibly happy and relieved that his friend was back and alive and well. He was never letting Rufus or Lucy out of his sight during a mission ever again. Just the thought of losing one of them again made his heart ache and his breath catch in his throat.

Never again, he vowed to himself. He would die before he let anything ever happen to them. He had already lost each of them once. He was sure he wouldn't survive a third time.

Letting his eyes stray back to Lucy, he smiled when he saw her apparently napping in front of the TV. Hopefully her half kid brother would be okay and Jess would leave him the hell alone. He still didn't know how to feel about this whole thing with Jessica, but anger was still the biggest emotion running through him. Even if she was carrying his baby. If that was even true. He just felt like he didn't know anything anymore.

With a shake of his head, he decided that focusing on these files would be the best way to help everyone. He just wanted this to be over and the sooner, the better.

It was only hours later that Agent Christopher finally called it a day and he realized it was closer to dinnertime than he'd thought, if the rumbling in his stomach was any indication. Stretching his arms above his head, he scanned the TV area, only to find out that Jiya was the one watching it now. Looking around, he didn't see Lucy anywhere and figured she had just gone to her room to get some rest. Now that he thought about it, he had seen her walking past him and in the direction of her room a couple of hours before.

Since it was his turn to cook dinner, he quickly washed his hands and pulled some vegetables out of the fridge to start working on a stir fry. He figured he would get dinner ready and then go get Lucy. She had become so withdrawn these past few days, and he knew she was barely eating, unless someone nudged her in the direction of food.

So he distracted himself for half an hour and, when everything was done, he rounded everyone up from the common room and started in the direction of Lucy's room. Knocking on her door, he waited for her reply. When he was met only with silence, he knocked again, this time calling out her name. But again, she didn't answer the door. Trying the knob, he opened it carefully, thinking she might be sleeping, but he felt his breath catch in his throat when the light from the hallway illuminated her room.

Lucy was nowhere to be found and the air vent was wide open.
