Re: Why did spock end up in the alternate universe??
Kills the rest of the argument, though. Either this universe REPLACED the original one, in which case, Spock would be obligated to try and restore his timeline regardless, or this is simply ANOTHER of myriad universes, in which case, it will exist along with every other possible outcome, and Spock's only obligation is to himself, and whether he wants to return home.
If the original timeline wasn't destroyed, why would this one be?
Perhaps, if I am very lucky, the feeble efforts of my lifetime will someday be noticed and maybe, in some small way, they will be acknowledged as the greatest works of genius ever created by man. ~Jack Handey
