Hamptons Hat Shop: Agent Guyliner approaches Gemma, shows her a picture of Bridget and says he has a few questions. Gemma: "About Siobhan Martin?" Guyliner: "No, about Bridget Kelly. Siobhan Martin's twin sister." Gemma's look either says, "WTF do you mean twin sister," or possibly, "You know, it looks like you're wearing eyeliner, but the crazy Lost fans seems to have proved, years ago, that you have ridiculously lush, thick, black eyelashes. Why is it always the men with the good lashes? Damn it." Commercial.

Beach House: Gemma returns to find Bridget reading trashy magazines. Bridget babbles about how the boys are out golfing and that allegedly, Angelina Jolie used to let her kids eat crickets. I have no time to Google that, so I'm choosing to believe it, because it pleases me. Bridget explains that she and her sister are no longer in each other's lives, because of a series of bad choices that Bridget made -- choices of which she's ashamed. Bridget confesses she never told Andrew. She knows she needs to, but she's not ready. Gemma swears he'll never hear it from her. Anyhow, Bridget goes on about how she wishes she could have saved her sister, and we know what she means. "Just when I thought I had her back, she was gone." Gemma: "God, Siobhan. I never would have guessed. All these years you were always so excited about your birthday. It must have been eating you up -- not being able to share it with your sister." Bridget: "It was our special day. I miss her." Oh Bridget, do you not hear what Gemma is really telling you about your evil twin?! We flashback to...

Six Years Ago, Lake Tahoe, Nevada: When Siobhan opens the door to Bridget, she reiterates that she doesn't want to see her. Bridget holds up a cupcake topped with two birthday candles and says, "It's our birthday. Red velvet. Your favorite." Inside, the apartment is full of moving boxes (given all my Buffy references, I probably should clarify that the boxes aren't floating or anything; they're stationary -- for packing stuff, when one is moving). Shiv is off to New York and a new life. "Andrew loves me. I can start over." Her jewelry box is conveniently lying open, on the table right behind her. She picks up the birthday necklace, holds it up and then tosses it at Bridget's feet. "I never want it back." That Bridget doesn't die right then and there of frostbite is testament to her inner strength. She picks up the necklace, gives me some Buffy boo-boo face, and runs out of the apartment. When Shiv shuts the door after her sister, she fights off her feelings and closes her eyes.
