In voiceover, Mary Alice says the world is a dangerous place, and we must defend ourselves from those who want to hurt us. We see an anonymous woman learning self-defense. Julie's getting in a car worrying about a strange man at the next one. Lynette's packing her office up, looking at Carlos (MAVO: "the employer who holds a grudge"). Bree watches Orson (MAVO: "the husband who won't let go) talk to Lamar. MAVO finishes up that we all try to defend ourselves so we won't get hurt. Katherine picks up her phone and fake-panics to 911 that she needs an ambulance, because she's losing a lot of blood. We get a close-up of the place on the table where the knife is as it's picked up and MAVO says, "Until we realize that our pain can hurt someone else." We stay on the table as we hear Katherine gasp and then see her hand drop the bloody knife back onto the table. We hear her fall to the ground. I guess handing the knife to Mike is how she planned to pin this on him? So she planned it all along, since he threatened her and she knew how he'd react. Tricky, tricky. And, of course, batshit insane. But that's what makes Dana Delaney such fun to watch this season.

Next week: The last episode of the year. Announcer Guy says it's the most shocking episode of the year, which began as a typical Wisteria Lane holiday and then became a tragedy. Not all will survive as a plane crashes onto the street. Announcer Guy: "But a hero will rise. In the most breathtaking episode of the season." I'll admit it: I can't wait.

DeAnn, a writer and editor in Portland, Oregon, is glad she's never had a boss like Carlos or a friend like Gaby. You can contact her at twopmodmars@gmail.com.
