Allison does her best to react fast. Even if it's overreacting, she can't let him go over the edge into the risks below. She's not interested in getting into a tug of war with whatever this is playing tricks with his mind, so she doesn't try to rumor him. She just drops her shoulder low to catch him off center and attempts to tackle him to the deck.

She'll apologize when he sees sense again.
