I think I figured out who Savitar is,he's Caitlin's father.Why else would he refer to her as "my child"?

This makes sense to me as the cast have all stated that the reveal will be shocking and all the fan theories are wrong.

So we have to throw all those theories out the window and think outside the box.

So this is me thinking outside the box.

And it makes sense.I think it's entirely plausible.

Why else would she agree to help him so easily?
