I'm very excited about Smallville's upcoming episode "Pandora." I think this Zod arc is Smallville's most impressive storyline and is something that would actually happen in the comic books. Hopefully, they don't screw this up.
Apparently Lois travels to the near future where Zod rules under the red sun. Clark and Lois appear to get in trouble and Oliver and Chloe bail them out, or at least try to.
There are still some things that don't make sense like whether Chloe will have any real rescuing skills or are the writers trying to make her useful without a computer and also the question of why they have kryptonite arrows instead of bullets. Hmmm. We'll have to wait until November 20th to find out!
