It might be fun to do some sort of game. I'm not sure what kind yet, though. Maybe an obstacle course that incorporates their powers? Or they could do some storytelling around a fire while eating marshmallows or something. It might make a good bonding moment. (Of course, assuming that, A, nobody is deathly afraid of fire and, B, nobody is too much of a pyro to be allowed around fire. Although we could probably just get rid of the fire for that, but it sets the atmosphere and...*rambles in a muttering tone to self*)
