Weiss, Rwby vol. 6 ep. 6

I think that Weiss reaction to the Grimm, setting them on fire with the wine, was so strong because by feeling that deep utter depression, it made her realize what her Mom must be feeling to drink like Qrow was. In a way, she was taking the power back, by destroying the booze and the Apathy, so that it could never hurt those she loves again.
