I actually was surprised that Martha survived to the end of last week’s episode – and given how Elizabeth (Keri Russell) seems to be seething about how much Philip’s “other wife” means to him, I’ll be just as surprised if she makes it to the end of tonight’s episode, much less to her new home in Russia, which she doesn’t want anyway, but can’t stay in the US, because the FBI is close on her heels. What a dilemma. What a show. And here comes Margo Martindale, returning as Claudia the former KGB handler, to either help, or not.
