'The Killing' recap: Donnie Or Marie
How Linden and Holder do detective work throughout this episode is, they sit around in their car and make up wild theories and then act as if their wild theories are correct, and eventually -- because the show is like this -- they turn out to be correct. So they get Roberta to admit that Chief Nicole is an abusive lover and breaker-of-bones, and eventually twist her around into giving them this elevator footage that supposedly didn't exist, which shows who the person is. (Also, it sounds like Roberta wasn't the one that put up the haunted-tree picture, but whatever. I have a theory about that.*)
But first, there's a lot of hilarious red-herring stuff where first you think it's Jamie, then Gwen, then Jamie, then Gwen, then Holder and Linden split up and one of them thinks it's Jamie, and the other one thinks it's Gwen, but then they decide no, it's Gwen and the other thinks it's Jamie, and then they get back together and it's like, "You got your Gwen theory in my Jamie theory! You got your Jamie theory in my Gwen theory!" Forever.
