When Lexie skirted around his question for a second time by latching onto another subject, Andy decided to let it drop. Just by doing so, she'd answered his question for him, as far as he could tell. If she was as much like him as he was starting to think she was, the avoidance of the answer was a big, fat, silent "no." No, she wasn't okay. There was probably nothing he could do to help her, either, short of telling her she was okay and that was something that he was just completely unwilling to do, even if he thought it might make her feel better temporarily.
"Yeah, there is, but you gotta have a fucked up leg, so you don't qualify," he said in a very low, apologetic, and official sounding voice. Then, he smirked. "Smile, dammit," he said, giving her a gentle poke in the side with one of his elbows - not enough to potentially (and unintentionally) hurt her; just enough for her to feel it. "You're way hotter when you smile." It wasn't that he was trying to flirt with her, but it was true...and chicks dig compliments. ...right? "Yeah, she's pretty good. I like her. She's no Doc Lex, or anything, but...Elliot's pretty cool," he said with a small smile.
Lexie's reaction to Andy's offer for a walk actually surprised him a little. A huff came out unexpectedly in place of a laugh at her eagerness and uncertainty. Like she thought he was just fucking with her. "Yeah, really," he laughed, standing and holding a hand out to her. Then he paused and started to pull the hand away. "...that's not gonna work is it?" he asked awkwardly, looking at her shoulder. Still, his hand was out and he extended his arm fully again just in case she thought it might not hurt to take his hand with her good one.
"You've been sitting here staring at nothing forever, Lex, and the longer you sit there, the shittier you're gonna feel. So let's get out of here. ...it's fucking depressing in here," he said quietly in a voice meant just for her to hear. It was depressing in the gym, but he didn't need or want anyone else to overhear, especially someone worse off then either of the two of them.
