Here's half a reply. I've been watching this on and off because Kim's been watching it from the beginning, and I'm usually in the room when it's on. I caught most of the second half of Season 2 via a marathon and I really liked it.
LAST week's episode was pretty mind blowing. This week's episode...more heart stopping, I guess.
I'll stick with it if only because it fills the half hour between Animation Domination and "Life's Too Short."
Are you sure Cersei was going to drink the nightshade? It seemed like she was going to have her son drink it. Maybe she'd drink after giving it to him, but I don't think it was solely going to be for her.
