Superman/Doomsday2007

Superman:
I haven't told you my identity for the same reason we haven't gone public with our relationship. Why we come here to be alone.

Lois Lane:
Well, try reading a gossip column. Practically all of Metropolis thinks we're dating anyway. You're clinging to keep one last part of you separate from us. And the only reason that I can fathom is that for an alien, you've developed a very human... very male fear of commitment. We've been together for six months. It would be nice to start calling you something other than Superman!

Robot:
He also goes by Kal-El.

Lois Lane:
Shut up!
