I don't get the whole Zod story line. Didnt he possess Lex and Clark banished him to the Phantom Zone? How did he get out and where did this army come from?
The implication is that Zod and Co. are copies of the originals and were from a time before Zod became "evil" and was sent in the phantom zone.
Chloe needs to die. She is turning into a whiner. Why is she spying on Oliver and the rest. I heard them talking about it, but the excuse sounded lame.
Chloe has outlived her usefulness on this show by several seasons. Personally, I don't think the writers know what to do with her anymore, so they keep giving her story lines that feel forced, unneeded, or goes nowhere (does anyone remember when she was a meteor freak?).
The last two episodes, she was all mad at Clark, but it was completely unbelievable (at least at the extent of it) and it didn't really work.
