I like this story. Lois is very Lois, attacking Clark when she finds out who Superman really is. She's lucky she didn't hurt herself while beating on him.
And Clark's reaction to Lois's attack - to stand there and let her whack on him - is so very Clark. He made a huge mistake, and now he has to pay the price.
I have to agree that the "Babe/Jerk" ending was hysterical. It also shows that they've both worked through the emotional impact of this episode. They'll be fine. I can see them exchanging these endearments in the newsroom, then smiling privately, then refusing to explain to Perry or Jimmy or Cat what the heck's going on.
Oh, "blinkered" refers to the things horses wear to limit their field of vision so they don't get distracted by things that aren't directly in front of them. Another name for them is "blinders" and you can see them today on horse-drawn carriages in cities. It's a great metaphor for Lois, a woman who focuses on what's right in front of her and ignores the peripheral stuff (like Clark) until she trips over it.
