Qrow doesn't have to worry about getting stabbed by this Schnee. If she and Qrow had the same history as he does with her sister, then maybe, but they don't. Qrow just kept secrets from her team, amongst other things. It's nothing stab-worthy, not when he's just as lost as to what his purpose is now like the rest of them. Thanks, Ozpin!

She can't even think about stabbing him right now, even if she wanted to, anyway. When she turns to face him, her eyes are wide and are watering.

"I need water!" Though it comes in gasps as she smacks her chest with her palm. Swallowing a buttload of powder was definitely not a wise move.
