"Alright." John meant more generally, like maybe there's something they could do on the ship once Craig's sufficiently stabilised somewhat, but they can take it one thing at a time.

"Let's take the stairs, pet." John takes the lead, again, slow steps and staying in front.

"You'll need to come down, with me." He can try going up, but that's moving away from Deck One, so he can stand there fighting it for another half hour or he can follow the annoying blond bloke with the accent.

"I'm feeling a wee bit peckish. Are you hungry?" Now he's just spontaneously throwing an itinerary together for Craig. After the safety briefing, he's free to peel off and go do whatever he likes of course, and John wouldn't care either way if he has company for mealtime or not. But it seems a little half-arsed to get Craig to the safety briefing and then fuck off.
