Chuck's phone rings. It's encrypted, so he hesitates -- I mean, this is his rehearsal dinner, after all, and you know the guy wants a break -- but answers it. It's Vivian, carrying out the scene we saw in last week's preview. She tells him she hopes she's not interrupting anything important, but she just called to make him feel pain like she feels right now. She says she's lost everyone close to her and has him and his family to thank for it. Chuck tells her they can talk about this, but she tells him to look around the room (well, technically, Vivian, he's not in a room; it's an outdoor courtyard) at his loved ones and ask himself which one she's going to take from him. She tells him she has another Norseman. He pleads with her not to do this; this is not her. She says she's already done it. Sarah can see Chuck's worried so she gets up and walks over to him just as he and Vivian hang up. Vivian flips on the Norseman. Sarah asks Chuck what's going on, and he walks around her and says he thinks Vivian's going to try and kill his mom. She grabs her ears then and asks what that noise is. Chuck turns, realizing it's her, sees she's bleeding from the nose now and watches her collapse. He starts freaking out, "No, no, no! Baby, baby, baby! He asks someone to call 911. The whole party gathers around Sarah, trying to help. Which is how we end it. I have to say it's pretty annoying that everyone else died instantly from the Norseman, but Sarah's somehow strong enough to survive (because, duh). However, I like that it's bringing a serious, scary dimension to this finale. And I also like that this is what Vivian chose for her first kill. (Though I do wish Vivian would stop being such a spoiled, stubborn brat and just listen to what Chuck's been trying to say to her this whole time: that he does want to protect her and be her friend. But it's probably too late for that now.)
