Wouldn't that cause some kind of time paradox if Clark is taken from an alternate future of his own universe and stuck into the past, thereby erasing the future from which he was removed? dizzy

I had assumed two different dimensions: Clark's: he arrives late and Lois had married Lex. Lois': there was no Clark (he never arrived).
