I really love the fact that as much as Vax is still nervous around Grog, Grog is now making an active effort to make sure he doesn’t actually get hurt
Case in point: Grog sees a great big pit opening up ahead of them. He tells Vax to go ahead carefully, and Vax does. The second Vax actually might fall, Grog panics, “No don’t fucking fall you idiot there’s a fucking chasm!”
Vax bitches but still, they’re growing!
