I love Pa Kent in the beginning and then he goes insane. I feel totally sorry for him when he's acting like he's anything other than Clark's real father. Then he has this bizarre instance where he's like "Of course I knew if I called you you would come straight to me, but after this that's a bad thing to do!" Um, Jonathan? That's not just about Clark caring about you in a special way because you're his father (which is a good thing) but because he trusts your judgment. You called him to something important and he listened.
