Get me caught up on "Smallville"

So I watched most of the first season, and I know it was mainly freak of the week stuff. But I keep missing new episodes and call upon a fan or two to help me learn what I should know in order to sit down at the next new episode and not be confused.

I’m mainly concerned with the continuing “myth-arc” (to steal an X-Files phrase), not so much the one-shot episodes. I’m a little fuzzy on when Jor-El made his debut and why he seems to be an ass of a dad. I know that Lionel has some of Clarks blood and is trying to learn secrets of immortality from it but where did he get it, why did he get it, who knew about it, etc.

Let’s just say, starting from season two, what happened? Easy request, no? :slight_smile:

I googled it for you. There’s detailed episode guides at www.devotedtosmallville.com
