Lee is... unsure what that means. Is that good? That's good, right? That Michael was saying nice things about her, true things? But she doesn't understand the confusion or the awkward silence that follows it. Now Michael's not looking at her and she doesn't know what that means, either.
"I did something wrong?" She tugs on her index finger with the opposite hand, her head slightly tilted to one side, uncertain. She's still standing where she was because she's not sure what the rules are here, and Lee is notoriously shy in public, anyway. She's too aware of all the busy industry going on outside for this to not count as public.
