Of course Lydia knew why he was acting this way, deep down. She didn't bother answering him because she didn't need to anymore than he needed her to confirm what they both already knew. It was for the same reason she kept acting the way she did every time she saw him now. Anything was easier than telling the truth, so why not just fall back on old habits?
They'd always been good at that.
Lydia tried her best not to dwell on their glory days, all of the best memories from their relationship that made her almost reconsider her firm position (though that position wasn't exactly what you could call firm, after the closet incident) on keeping Matt at arms length. Memories she was more keenly aware of now than ever. Once upon a time, they'd actually loved each other and shown it. They used to have fun together, didn't they? She told him she missed it because she still couldn't bear to say that she missed him, but it might as well mean the same thing.
To make matters worse, she really didn't have anyone else to talk to about this. Daniel would be sympathetic to the point that it eventually infuriated her. The twins? They couldn't be trusted with anything approaching relationship advice. Freya was out of the question if she was meant to be Lydia's student, and not to mention, she was still a little cranky with the younger, enthusiastic jedi for her stunt with the closet door. And Lydia tried not to bring it up with Lachlan. He might have been her friend first, but he was Matt's too. She wanted to respect that.
The only person she actually wanted to talk to about this was Charlotte, but something held Lydia back from doing that too. Maybe because the Charlotte who had known Lydia before Matt, and had a front row seat to the early Matt and Lydia saga before her accident, was virtually gone. There's really no point, she thought to herself wistfully.
In the midst of her Matt-sized turmoil, Lydia felt his hand on her arm, the familiar touch immediately pulling her out of the temporary daze she hadn't fully realized she'd fallen into. He'd always been good at that. No matter how stuck she got in her own head, Matt had the uncanny ability of bringing her back with just a touch. To bring her back to him. Maybe a lot of things had changed, but there were still some things that hadn't.
Old habits died hard with them, but not all of those habits were necessarily bad.
She only half-heard what he was saying, Matt's words fully sinking in a moment later. Jacket's behind you, if you need it. Lydia glanced up at him, searching his face the way she used to when she was trying to decipher whatever he'd just said or done that surprised her. Such a small thing, but the offer had an immediate affect on her that Lydia couldn't have predicted in a thousand years. Not since their break up, anyway.
It unraveled her completely.
Almost like muscle memory, Lydia's body twisted to turn into his touch instead of away from it, finding herself pressing into his side before she fully realized what was happening. She forgot all about being cold. Just like that, the pride she normally clung to in order to keep herself from doing just this melted away, and all that was left was Lydia. No more walls, no more excuses. Only the need to be closer to him.
"Matt..." She echoed his name like he had hers, the space in between full of everything left unsaid between them. Lydia couldn't bring herself to say anything after that, so she did the one thing she promised herself she wouldn't do when she came here today. She tilted her face up to his and kissed him. Just once, eyes only half-open as she sucked in a small breath after, letting her forehead bump gently against his instead of pulling away. Unable to face this and suddenly incapable of denying it.
A moment like this couldn't last, she knew that. Sooner than later they'd be back to ripping each other's heads off, but even after everything, doing this still felt like the most natural thing in the world.
