Easy now! I enjoy that thing and want to see it show up again in future issues. In fact, I want it to have its own monthly title, or at least a backup feature in Action Comics.

But despite the physical similarities, that wasn't Luthor.
And he's dead. Superman killed him.
To review: Superman killed a guy for no particular reason. Again.
See you tomorrow!
