Qrow & Elsa
The temperature dropping slightly didn't go unnoticed by Qrow. Even if he didn't know about her abilities and how she sometimes had trouble controlling them, it was still quite noticeable. It also just confirmed that this was definitely not the best time to lay everything on her and that someplace less public and crowded would be better.
So he kept up the lie that he didn't know her from before. He hated doing it, but at the moment, he felt it was best. "That's good. Weiss and I are from the same world," he explained. "So we kind of known each other for awhile now." Except they weren't as close as they are now.
