I just remembered something about the SV JL that I never understood. Was there a specific reason why they only ever called Bart Impulse, and never The Flash? I was looking at his comic bio and I see that he was appeared to have a fairly short career as The Flash, but he was as far as I know the only Flash in SV, so I would think it would make more sense to call him that, especially since it is much more recognizable than Impulse.
