Ooh, yay, I've been looking forward to this episode! I'm sure introducing Smallville to both Lois and Cat is going to be a treat.
I love their three-way press on Carol Sherman. She seems like an interesting character; I hope we see her again.
So Luthor is directly funding Trask. Interesting. Trask seems more okay with having a mysterious overlord than I would have expected. I guess he's... ah... mission-focused.
