On the other hand, why can't Clark stay in the past? All he has to do is set up the Charlie King identity.
But... what if past Clark starts hearing about mysterious rescues made by future Clark (Charlie King) in the past? What will past Clark do? Certainly he'd be interested in finding someone who is just like him (literally).
And that's only one problem. So many others!
Will Clark get back to the future? And what's happened to it, given all the time he's spent with Lois and everything they've done together?
