After all this time, Jack is fairly sure John, at least, has no real interest in him in that fashion. Serph, the jury's still out, but he's not going to push on it yet either. So he doesn't take it as anything other than the same invitation as before. "I'll be there, then," he promises again.

And he's aware he clearly lost John at some point in there, but he'd really rather just leave this conversation for after Serph has his talk with him. It will be easier when at least those two are on the same page. He's content to let it be. Instead, he says, only half-teasing, "But you, my friend, need to promise to take a shower at some point, too. When is the last time you actually got clean?"
