Time Travel. I normally love it, so going into the Season Finale, I was pumped.
They got it… mostly right.
The time travel part is there, and the animation is great, but there was zero explanation as to how the spell actually worked.
In fact, I still have no idea, even after thinking about it for quite a while.
So, instead of writing a fic in which time travel is explained, I wrote a fic in which time travel is utterly broken.
Starlight is really in for it.
