Being not much in the mood to argue, Donnie's glad when Leo does drink. Not nearly enough, but it's still something. His eyes flick towards Leo's back, brow knitting in dismay as nothing seems to have helped his brother's shell. Unconsciously his arms tighten around him a little more, loosening only a touch when the bottle's offered back to him.

He looks about to object himself, but he takes it to take a few gulps. Leo had healed the worst of his injuries, but it still feels better having a drink.
