Lionel Luthor is coming back to "Smallville" this week. Sort of. Kind of. Almost. You see, he's going to be on the show, but he's going to be there in this alternate universe. Clark will be there in the alternate universe too however, which is why we're going to get to see Lionel again. It really would be something of a slap in the face to us, the audience, if we were just told that Lionel Luthor was alive in some other universe but that we wouldn't get to see him. That really would be thumbing their noses at us, wouldn't it? Gee, think they'll mention Lex?
