At almost the end of Roy and Ed's fight in episode 13, there's this dialogue:
ED: Finish me off.
ROY: I will.
Now, aside from sounding incredibly dirty out of context, what does this mean? Every time I watch it, despite knowing that it's not a serious fight, I still can't help but think that Roy is about to immolate Ed, especially since he begins to snap his fingers. I guess he could just singe him a little, but I can't see how that would be any more conclusive to winning the fight than just having Ed on the ground, which he already is.
So... what's going on there? Am I just overthinking this?
