I was talking to the OP (If I don't put the username in the beginning, I'm always talking with the OP. ^_^).

And depends on how much the character changed the past. If he displayed enough power to alter the whole past (in a universal way) then he's Low 2-C. If he changed some events via messing with the continuum with 4-D power (but in a less than Universal scale), then High 3-A would do the trick.

...As for changing the past without altering the future, I'm not sure if that's possible at all (I'd say it's impossible, but then again, fiction).
