Clark finally knows that Chloe knows his secret, Lana and Clark are back together. Clark loses his powers after the sun goes down;after he defeats those two Kryptonians that arrived on the space ship (though him losing his powers is obviously, temporary).

Clark gains the Fortress of Solitude, And at the end that guy who played Spike on Buffy/Angel makes an appearance (as if it wasn't obvious by the comercials). I like this show even more (although before, around Seasons 2-3 it was kinda repeatative).
