This takes place sometime during the course of "The Couple in the Cave" 6x02

... ... ... ... ...

A sharp trill resonated from his cell phone on the nightstand. Hannah let out a sleepy groan as Seeley pulled away from her to read the text, letting cool air seep between them. She squinted blearily into the dark as the ghostly light cast shadows on the walls of his bedroom. "Who's that, babe?"

He didn't answer, seemingly distracted by the message on his screen. Hannah turned her body towards him. The clock gleamed a red 2:04 am.

"Seeley?" she tried again. His thumbs were quickly moving across the keyboard, formulating his reply, but he had the phone angled away from her slightly so she couldn't see the screen. "Who is texting you so late?"

"It's work, baby. Go back to sleep." Hannah sighed and slipped her body into the circle of his outstretched arm, laying her head on his shoulder. He moved the phone to his other hand so she still couldn't see the message. Is he doing that on purpose? She closed her eyes. Seeley turned the phone on vibrate and laid it on his chest, obviously waiting for a response. Hannah could feel his heart thumping against her cheek, a brisker tempo than normal.

"Is everything alright?" she murmured. In Afghanistan, he had never gotten texts in the middle of the night.

"Yeah, it's fine." He stroked his fingers up and down her naked back, lulling her back to sleep. Hannah had almost dozed off again when his phone buzzed, twice, louder than it should be in the quiet of his dark apartment. She startled at the sound.

"Ughh, Seeley," she pouted, "it's the middle of the night." Once again, he didn't answer. She leaned her head back to look at his face. His eyes were darting back and forth quickly as he read the message, concern evident in the growing crease between his eyebrows.

"Shhh, it's nothing," he said distractedly. Irritated, Hannah turned away from him and huffed out a sigh. She tried to relax, but she could feel Seeley's tension next to her, and the unnaturally bright light of his phone wasn't helping anything.

"I'm gonna go out to the living room for a minute," he whispered, placing a kiss on the nape of her neck. She knew he couldn't see her face, but Hannah rolled her eyes anyway. "Seeley," she whined.

"I'll be right back." She could hear him gathering his clothes from the floor and pulling them on. He closed the bedroom door as he left.

Who is he talking to? She wondered, perturbed by his secrecy. She sat up in bed, listening intently. After a few seconds she heard the low rumble of his voice through the door. He was obviously making a phone call. She expected his tone to be curt and professional like it usually was when he made business calls. This time, though, his voice was sensitive, almost soothing. His words sounded muddled. After ten minutes or so, she couldn't take it anymore. She tiptoed out of bed and moved closer to the door, hoping to catch what he was saying.

"I know, sweetheart." His words were warm, dripping with affection. "It'll be okay, it's all over now," he said tenderly. Hannah's heart was pounding. Is he talking to a woman? she wondered. Surely, not. Seeley didn't strike her as the kind of man to cheat on his girlfriend. But a gooey phone call in the middle of the night? She sat back on the bed, her mind racing. I'll just ask him about it like a damn grown up, she decided. There was no point in sneaking around. Obviously he loved her. She going to move in with him, for god's sake.

Hannah heard his footsteps moving back towards the bedroom. The door swung open, slowly and silently. A small smile curved his lips. Seeley was typing again, sending another text. He looked surprised to see her awake, sitting wrapped in a sheet on the bed.

"Who was that?" she asked, careful to make her voice sound casual and not accusatory.

"Oh, just Parker," he said, rubbing his eyes tiredly. "He had a nightmare."

"Oh," Hannah said, keeping her suspicions to herself. She hadn't met Seeley's son yet. Maybe he was telling the truth. "I thought you said it was work."

Seeley got into bed and pulled her back to him, kissing her shoulder. "The texts were from work, but then Parker called."

Hannah was amazed at the ease with which he lied to her. She was almost certain that he was the one who had made the call. Did he think that she was too sleepy to remember the course of events? Obviously believing he had placated her, Seeley relaxed, burying his face in her hair.

Hannah laid awake for a long time. Her mind was racing, putting the pieces together. Only when Seeley had turned onto his back and was snoring lightly did Hannah make her move. Slowly, she maneuvered out from under his arm. She gently reached over him and lifted the phone off of his nightstand. She felt a little guilty about this invasion into his privacy, but the twisting feeling in her stomach propelled her onward.

Opening up his text messages, she saw that the last one had been from "Bones." Temperance, she thought, irritated. Technically, he did work with her. But when Hannah read the conversation that transpired between them, she knew it had nothing to do with business.

... ... ... ... ...

2:04 - I'm sorry to text so late. I hope I didn't wake you or Hannah. I just can't sleep. I'm having that nightmare again.

...

No, I'm awake. It's no problem. Gravedigger? - 2:04

...

2:07 - The man from the foster home.

2:07 - Never mind. I'm sorry, Booth. I'll be fine. I didn't mean to disturb your evening.

...

Really, it's fine. I'm happy to talk to you. I'm sorry about your nightmare. He can never ever get to you again. -2:08

Bones? - 2:11

Can I call you? -2:12

...

2:12 - Yes

...

2:35 - Thank you, Booth. I've really missed you these past months.

...

I missed you too, Bones. More than you can imagine. Text me if you wake up again, ok? 2:36

...

2:36 - Goodnight :)

...

Night -2:36

... ... ... ... ...

Hannah's stomach churned with unease. She had only met Temperance once, but she knew already that she didn't like her. She resisted the urge to wake Seeley and demand an explanation. She would wait, she decided, and collect more proof. The one thing Hannah knew for sure was that she did not want her boyfriend spending any more time than absolutely necessary with his gorgeous partner. As far as she was concerned, Temperance Brennan was the competition. Keep your friends close and your enemies closer, she thought grimly. She was going to have to befriend the bitch.

Just a little idea I had. I think I have enough for at least one more chapter. I typed it quick, so let me know if you spot any errors. Please review and let me know what you think!
