Qrow & Elsa
While he didn't actually admit to anything, Elsa felt like there was more to Qrow, to them, than he was saying to her. Maybe he was holding back to protect her, to protect everyone, given he probably knew about her abilities. If he'd known her before. There was a chance that Elsa was sensing something that was not there. That maybe this was the first time they had met. She could not help, but feel differently though.
"If you know each other, does that mean you might have known me...from before?" Elsa knew Weiss had known her from before; shew as working at the shop that she herself had established when she'd resided in Madison Valley. Elsa could not remember doing it of course, but Weiss had already confided in her that she had owned the shop. If Weiss knew her and also knew Qrow, was it possible Elsa had known Qrow too? It felt logical to Elsa.
