After Cisco and Barry headed home for the night, she stayed at the Labs. She couldn't leave. She just couldn't go back to her place. What would she even do there? Sleep? Yeah, she didn't think so. She was pretty sure she wouldn't sleep again before she actually confronted Harrison about everything, however dangerous that might be for her. She didn't care. It was just something she needed to do.

She decided to wait for him in his secret room out of all places. It was her best option because it would give him no excuse for lying. She wouldn't be able to stand it if he dare lie to her now. She needed the whole truth, no matter how badly that would break her. Who knew, maybe afterwards there wouldn't be anything left of her or her heart, but she needed this all the same.

She contemplated actually texting him to meet her there, but in the end she didn't have to. The Labs were dark and quiet now and the secret door suddenly just opened for him to step inside.

To her astonishment, he wasn't any bit surprised to see here there and she had the worst of feelings that he'd known about every single one of their steps despite them being so careful. He wasn't stupid as the doctor they all knew, so she could only imagine how smart he was as the speedster they all feared.

"Who are you?" she immediately asked him in an accusatory tone, her heart racing again, her world starting to go off balance once more. It was all too much, too many emotions, but she knew she needed to handle them now and stick to the end, to listen to him and to get her closure. Otherwise she'd never rest, sleep or trust any other person ever again, especially men.

His blue eyes settled on her own, taking into her shaky state and widened pupils as she actually got to see him standing up, not used to his height.

"I'm whom I've always been this entire time, Caitlin," he eventually answered, honesty clear in his voice along with… was that actually nervousness or fear? She wondered, briefly regaining all of her senses once adrenaline kicked in. She could see everything sharper now and she actually felt her courage return. He wasn't going to hurt her if he hadn't done that already, right? She could grill him all she wanted, the state of her heart after that be damned. "At least when it comes to you," he added after a moment during which she was just eying him, trying to figure him out. "I never lied about my feelings for you, Caitlin."

"But you're the Reverse Flash. You killed Barry's mother."

"There are always two sides to every story and nothing is ever as simple as black and white. I trust you know that."

"Then tell me," she encouraged him in a voice that didn't seem to belong to her anymore. She forced herself to detach from any feelings, just remaining cold and steady because that was the only way she could handle the situation now. "Tell me your side."

Harrison sighed, brought his hand to rub on the side of his head for a moment before dropping it and facing her bravely, "The Barry you know is not the Barry in the future, Caitlin."

All was said. All the cards laid on the table. All that was left was for her to decide which side she chose.

"Now that you know everything," Harrison added after a longer moment of silence during which she refused to speak up, "you're free to go if you wish."

She wasn't even aware he would keep her there till he'd tell her everything, but maybe it even made some kind of a sense that he would want her to have all the information before she would run away and make what probably was the biggest and most difficult decision in her life.

She was still just standing there, not moving, her eyes starting to bore into his as though she was desperately looking for any sign there to prove that what he'd told her was the truth, that what he felt for her was also so. Or maybe she knew and saw all of that already and was just too scared of what she would do next, of the choice she had already seemed to make, but couldn't accept it in her brain just yet.

Harrison decided to risk it then, making a step closer and when he made sure she didn't try to back away from him, he finally arrived at her side.

"I meant it when I said you're free to go," he told her in a surprisingly soft and husky voice, "but if you stay, my dearest Caitlin, I promise you, you will never regret your decision. You are remarkable. You never cease to amaze me and I actually think you may be the one person who can truly understand me." By the time he finished, his fingers were on her face, his quiet voice in her ear as he moved closer to her, feeling her own ragged breath against the skin of his neck. "Caitlin, I love you," he added then before he found her lips and placed a passionate kiss there, not slowing down, needing to show her how much. He needed her to know how much he wanted and needed her and that without her, he wouldn't enjoy his next step anymore because somehow she had became his life, not revenge.

"Show me." She was actually more surprised by what she said than he was, still not able to believe she did so. Yet, it was what she wanted. He was what she wanted.

She did not see coming what he would do next, though.

He used his powers and before she knew it, they were both naked and he turned her around, her eyes now seeing the yellow suit there in its place, his hands on her breasts and then riding lower to check if she were ready. But it was enough to get her excited and he released a heavy and needy groan at his discovery, instantly plunging himself deeply inside of her, slamming his hips into hers, never ceasing, not giving her any respite, taking her from behind, showing her whom he really was at his core, but in the same time loving her so much.

When she eventually came around him, being pushed so far over the edge, she knew she was screwed. He was her doom, the true ruin to her life.

So be it.

"Next time I can wear the suit when we do it," his voice then reached her. "If you want, of course."

She found herself smiling.
