The rumor that Barry accidentally crosses over to an alternate universe, and runs into someone there who's also pretty fast? A guy in red and blue...PLAYED BY TOM WELLING?
Ooops! Looks like someone posted about it below.
Quote:1. Given Tom Welling's reluctance to even put on the Superman suit, I highly doubt this will come to pass.
I kind of get the feeling somewhere in Welling's Smallville contract it said he was never to wear the costume.
Quote:2. Geoff Johns himself is on record stating that Superman, or Batman, will never appear on Arrow or the Flash.
You are right about costume, basically he was not to becoem Superman for real until last show...
And this could be really awesome of they could pull this off with him returning as kal for one final fling...
Maybe Flash creahes unto that earth, and alters history so that darkseid conquered it, and so has to redo that event?
