This is EXACTLY what I always imagined would happen if they ever cast Welling back in the days. That they just explain that Smallville was an elseworld tale with no real connection to the mythology of supermans original upbringing. Just another version of his life.
Like if Tom were cast then start that movie in the Fortress & we find out that all 10 years of Smallville was just training & he has been in the Fortress for years & the movie = training is over then cue the credits & Clark never really meeting everyone or fighting so many bad guys so early in his life & never becoming friends with Lex & Chloe was never real
Mwahahahahaha
