I always thought (hoped, really, because knowing this show, it was never reasonable to expect) that "sacrificing" Shereen would be the one bridge Stannis would not cross, the one thing that would finally make him kick Melissandre in the cunt and send her packing, one way or another. I'm truly disappointed he made that decision and I couldn't possibly give a damn what happens to him now.
This entire season seems to be about everyone getting their asses kicked. There's still one episode left, but I don't get the sense there will be any major victories next week. The one thing I have really enjoyed about this season is that some of the plot lines have come together, e.g., Sansa and Theon (also, Sansa finding out Bran & Rikon are alive), Tyrion and Daenerys. But Sansa's getting raped every night and Tyrion's tenure as Dani's adviser was famously short-lived, so...
And it's too bad Drogon only had seating for one. It will be a miracle if Jorah et al make it out of that arena alive now. Missandei, Daario and the rest of them have gotta be saying, "Hey, what about us?" Dragon should have been able to fry all of those fucks in a few breaths; even he kind of got his ass kicked.
