Superman has put Superboy though a Virtual Reality tour of Krypton's history, up to it exploding. Basically, Superman wants Superboy to spy on Cadmus, which Superboy isn't very comfortable with. After all, Cadmus is his home.
But Superboy being an "inside man" isn't the only thing...
I have something in my eye.
Now that Kon-El is not dead, does this mean Dan DiDio... doesn't hate you? ... THE WORLD DOESN'T MAKE SENSE ANYMORE!!!
