Moffat is now a murderer. He killed the Master. Major character of the series. This is inexcusable, I'm not staying around for the Christmas special!
I might be wrong but didn't she disapear in flash of blue teleporty light and not dissolve into a a flash of orangish light. I'm sure when she killed the other people it was orange and when she teleported off the plane it was blue. So I assumed she'd escaped at the end. We weren't meant to think that she died right?
