[ Sebastian should count himself lucky that Spike didn't swing his torch at him, though in retrospect that might've been the better option. As it is he drops it during his brief flight through the air, leaving it to burn on the ground. Had he been human, that hit into the trees could've seriously injured him but as it is it just knocks him about a bit. Nothing big, really. He does this every night back home.

No glory to win, no real argument to settle — he's not even entirely sure why this is a thing that's happening, other than that Sebastian is a complete and utter psychopath. You don't mess with those without good reason. ]
