Okay, Carol, I've officially decided that you're evil. You let them go back home but only *after* this L&C have divorced Lana & ditched Joe, and probably *after* the other L&C have gotten divorced, themselves! Which means that had time for one quickie before heading into a universe where Clark has probably been making time with Lana....
They're never going to have sex again, are they? You'll just keep jerking them around to universes where Clark is married to someone else.
Like I said... evil.
