[yeah smoke is pretty consistently coming out of her mouth at this point btu she's ignoring it.]

I think what might have happened is... maybe Danny and Vane were in the konbini? The shelves were heavy that were blockading the door, Vane was really strong, so he could've pushed them. And then someone broke into the konbini and used the drum to make Vane kill him? And then they killed Vane... somehow, maybe they made him slit his own throat or something, and carried him in the shopping cart to Fox dorm.

... Just guessing. This might all not be even close.
