It's implied that a Time-Turner can never be used to alter history, and that everything done in the past by way of a Time-Turner is already in the timeline. Still, that doesn't leave out the Chrono Trigger trick...
This is uh an elaborate joke, right?
Also, -1 star for reminding me of Evanescence or whatever the fuck. That was something I could've done without remembering.
But what about Mrs. Puddinglingtonsonchester and Professor Hiram P. Dibbinglington and Bombo the Beast that Walks Like A Man and a few dozen other characters with "whimiscal" names?!?!?
