The following post may contain mild spoilers about the tv series Smallville.
I barely remember. All the plotlines I didn't like came together - the Lana-witch-thing, Jason and his mother, somehow the crystals triggered a meteor shower onto Smallville (again). At the end Clark found himself in the Arctic. Maybe the writer should've put up a sign "Build Fortress Of Solitude here" to make it more obvious. Lois, after a car accident (LOL), was looking across a devastated Smallville. Nice scene. Curtain. And I think Bo Duke was allegedly hit by a meteor. But my bet is he'll get killed midseason 5.
