Any specific kind of action shot or just some dynamic pose kinda thing? Otherwise the first thing that jumped to mind was him brawling with Andrew, which does actually happen at some point in the series I'm currently working on, although the viewer doesn't get to see as it's dark at the time XD And quite possibly at other times as well, it's not the first time they've had disagreements ;D
Dealer's choice :) It's your universe, a character that I hijacked is just living in it.
