Lately I thought about, what would Trask do after the New-Kryptonian invasion (if he had lived long enough). He has always accused Clark/Superman of being only first alien to brainwash the humans doing the PR...
Perhaps he would run through the streets jumping
and screaming 'As I've said!' or 'I was right!'.
and then ending like this
because there is nothing left to do for him.
What reason could he find to hate Clark? I couldn't find anything.
