Strange just silently fumes, glaring at Childermass's general direction. Recovering plus the fight plus Strange's ever growing annoyance that Childermass won't tell him what happened have wound him all up into a ball of nerves. Fuming still, he heads back towards the basin, sitting back down in front of it.

"For your sake, I hope he's generous enough to tell you." It's said like Strange wouldn't tell Childermass himself but he knows that if something interesting happens, of course he's going to tell Childermass. He's missed that feeling of working things out with another magician.
