You didn't have an "Other" category so I chose the least mean suggestion(cause neither you or Paul are idiots)I've had tons of ideas about how alternate universes and time travel works. You kinda have to point out that if alt Clark were removed from his timeline, then his timeline would go on without him, but a time traveler could bring him back to any point along that timeline, including the instant he left. That would work for any space/time/continuim traveler, so you've got tons of room to make up whatever return scenarios you want.
And I say get Crazy! Don't let any specifics of "made up" rules bog you down. This story has been an awesome read and I for one plan to just keep taking it as it goes...regardless of my run on tissues.
TEEEEEEEEEJ
