I watched most of them, but that last one was weak. Nina? Give me a break, she's done a lot more harm to the assassins' cause than good. You can tell this was a case of the writers going "Dude, we need to pull something they'll never expect.... We'll have NINA be the traitor! Even though it doesn't make any sense!" Don't get me wrong, I love unexpected plot twists...but they have to make sense! These folks need to read books by Glen Cook and George R.R. Martin to learn how it works. They have people dying who you think are vital to the story, and others who you thought were dead turning up alive, and traitors who aren't really traitors etc. and it's all masterfully done, making perfect sense after the fact. Oh well. I guess much can't be expected from tv writers.
