So Peter climbs back downstairs, ready for the next plot beat.
"But anyway, back on the original topic, yeah, when I just turned out to always have been a vampire hybrid I got witchcraft of the sort your world throws out, sometimes. And I am, I think, just straightforwardly a half-vampire hybrid now, so whatever inferences you were drawing from the difference between us and how it affects the power should assume that much."
"Hm. I've met one other witch half-vamp but her power wasn't remotely as quantitative as flight. It's not obvious to me why you'd be slower than me, though - possibilities include that it's directly derived from landspeed somehow, so it's based off bodily strength and agility even though those aren't in play, or that we're flying at the speed of thought, or that I'm more aerodynamic, or that your special snowflake magic thinks it's fun if you get a longer training montage."
"It's... probably not that last one. I think the personalization options here make sure that if I'm not as good as you are there must be a reason for it, there's not going to be a training montage just so that a training montage can exist. Speed of thought seems maybe plausible? How would we test that?"
"I dunno, do you have a way to suddenly think faster? Failing that we could play video games and see if I win by a similar margin."
"Does the bar have video games? What am I asking, it's a magic interdimensional bar, of course it does. Yeah, alright, let's do it, training montage time!"
