Even after outright volunteering for this, it takes a while to talk himself into it. He supposes that, on some level, he was hoping he would make the offer, and she'd turn around and say she wasn't serious, or she was only trying to make a point or something. Anything that'd let him off the hook.
But no. She'd gone and got all grateful, and pleased about it. So now he has to follow through. Although yeah, he's thought about not doing it and telling her he has. But that's a bit underhand for him and besides, he's pretty sure Guppy would tell on him.
So. He's strengthened his nerve with a few stiff doubles, told himself to stop being a jessie, and reminded himself that there's potentially a really good payoff for going through with this. And so here he is, striding into the infirmary as if he owns the place.
He's got to be around somewhere. He's never bloody anywhere else.
