"Oh," she was not sad, and you could prove nothing. The way her head turned dejectedly was because she had been... remembering... something else that was sad, that was all, and had nothing to do with the fact that Tyler had said he wanted to be alone. Nothing at all. "Should I... did you want me to..." she made a movement towards where the elevators were, figuring that now that she knew he was safe, at least, she could go and do something else without having to worry.
At his question, she flushed and looked away evasively. Instinct told her the correct answer to that question was yes, of course she had helped with the cleanup, no she hadn't spent the entire time looking for him. Instinct was to lie. But at the same time, she didn't want to lie to Tyler, so she settled for something in the middle.
"A bit," she said. "There was all kinds of broken glass, and they told me to stay away from it. And there was all kinds of other broken things, and torn things, and some people were getting hurt from the cleanup and I couldn't find a good place to help," which she thought would have been true if she'd actually been looking for a place to help rather than looking for Tyler. "Should I help more?" she asked, sort of dully. She didn't really want to help clean. Cleaning was boring. But she would if he asked her to.
