[Even if he's still pissed at Dave, that doesn't mean he can't think of how to deal with the situation at hand.]

I'll stay here. I'll call in to work, say I'm quitting, find something else once Dave's awake again. One of us has to watch him and guard the door in case his jackass brother comes looking for him, and Rose, you probably couldn't fend him off as well as me. Plus, I've been here longest, so even if I can't, I've got stronger Pokémon than all of you. Besides, when Dave does wake up, he'll need someone here to explain what happened.
