I think Lex should interrupt the Clark and Lois wedding, take a big shit in the middle of the room and say "That's what this show was when I left it and that's what this show still is today."
No, no, I'm expecting Lana to crash the wedding right before they exchange rings, screaming, "Clark, I'm cured! Don't marry her!"
Clark will super-shove Lo halfway across Kansas, with a big, douchey grin on his face.
I'm just sayin'.
Don't steal my joke!
If that happens, Clark and Lana will drive off in the sunset with the banners "No flights! No tights!" and "Angst Forever" on his pick-up truck. With Kara flying in the background and Chloe being forced to smile at this drivel.
Of course, it would be really funny if Clark ran to Lana, only to suddenly fall on the floor. Lana lied about being cured and decided to kill Clark in revenge. Would totally redeem the Lana character and make it a great series finale.
