Lois: Jimmy, he was calling from near Blue Peak, the same place where where Sup... Oh, no. He just couldn't be!
Jimmy: Just the same, the next time Mr Kent's around, I'd like to put a Geiger counter on him. Then we'd find out if he's Superman.
Lois: It's what makes me wonder. Maybe you can't. Clark says he can't come back. And why can't he, unless... Unless he's Superman.
