What happens at the end of Smallville season 8?

Answer 1

The JLA want to kill Doomsday/Davis Bloom but superman being who he is is against it. The JLA goes over his head and double crosses superman trying to take out Doomsday. They fail. Superman goes after doomsday having an epic battle with him and ends up burriying him alive. Jimmy finds out Clarks secret but is murdered by Davis Bloom. Chloe splits Daivis Bloom from Doomsday using black Kryptonite. Jimmy gives Chloe the Watchtower as a present and they make up before he dies. Lois dissapears into the future (we think). Clark is overcome by guilt and leaves his human side behind saying that Clark Kent is dead and he will now focus all his energy to becoming the red blue blur.
