And while Taylor is fast, I don't think she's quite so fast to do that all in between the blink of an eye and then back...
Assuming we're talking about her having the powers of DC comics top-tier Flash, I'm sorry to say it, but you're just wrong. Flash is so fast that he should be able to resolve every crime on earth essentially by himself, and the reason he doesn't is because either DC isn't smart enough to write their stories from that perspective, with the changes that would mean for the world, which is understandable, or DC thinks it would make every other comic book they sell kind of boring because no-one else would have anything to do, which is, again, understandable.
Having a fanfic which centers on a newly minted Flash character neatly solves both, since Taylor is still learning she's more broken than an armless penguin that dreams of flight, and since we don't have to care about anyone else's perspective.
DC Speedforce super-speed is probably one of the best alt-powers for Taylor to have, since it starts slow, but scales to the point where she could probably give Scion a serious fight alone. Not beat him, you need dimension piercing nonsense for that, but she could fight him, if she learns enough.
For reference, at points in DC canon, Flash has both literally
outrun death, and admitted to thinking in
attoseconds; a unit of time so small the human mind can't even understand it, really. Too many zeroes.
Is that stupid beyond belief? Yep. But thecoffeeguru didn't make those rules, that was DC. Anyway, given what she's up against, it's not as broken as it could be.
Whether it's a good idea to write that story is another question, whether that can work and maintain tension. We'll see. It's good so far, and Taylor/Earth Bet has enought problems it
should be doable.
