Pepper, as typical, would have shown up early for anything Torunn might need done and assisted throughout the night, because she's Pepper Potts and can't help herself. This time she had Tony there to offset the urge to sideline herself, so there was some mead drinking, lots of socializing, and maybe even brief participation in knife/axe-throwing?
James was just straight up Last Time 2.0, with being supportive of his girlfriend, eating a ton of food, drinking a ton of mead (across the potency board), cheerfully challenging people to throw-offs, getting more complimentary and affectionate about Torunn as the night went on, and probably getting into SOME kind of non-serious/funny trouble at some point.
