Since Tom learned about Toby's MJ being different than his MJ. Saide could be the MJ he was always destined to be with. He could also end up meeting his Gwen Stacy and be put into a triangle if they wanted to. Since he hasn't started college yet he has an opportunity to meet all new characters that have yet to be introduced. Mayday would be cool, but I agree the multiverse is getting old and not adding anything to the movies at this point.
