Over at the Whitehorse shack, Emma tells Ethan that, on the college trip, she couldn't help fantasizing about taking over Sutton's life forever. She realizes now that was a sick, crazy thought. She wonders, "What happened to us? It's like our moral compass just... snapped." Ethan insists none of this is her fault, but she's not so sure. Just then, Thayer drives up and gets out of the car with a grave look on his face. He tells them he thinks Sutton is dead and says he thinks he knows who killed her. He goes through his mental process, telling them he realized the twins' birth mother would have the most to lose if the truth came out. He followed the trail of the art gallery addresses Sutton was visiting several weeks back and found out that one of them was a psych clinic. He called them and learned of Annie's breakout. He apologizes for telling Emma this way, but she says she had twintuition about it and realizes once and for all that she has to tell the Mercers the truth.

The guys join her as she walks into an empty house. They head into Sutton's room as the horrible news still sinks in. Ethan and Thayer each give personal mini-eulogies for Sutton, Ethan citing her vibrancy and unpredictability, Thayer admit he fell in love with Sutton at first sight back in second grade. As they pour one out for their homey, Ted is elsewhere deep in thought and drowning his troubles in Scotch, and Justin is burning the box o' mystery. Back in Sutton's room, Emma recalls the first time she heard Sutton's voice, how she felt an "electric charge" at knowing her twin. She regrets not knowing Sutton as well as Ethan and Thayer did, supposing they would have been inseparable if they'd gotten to know each other better. She tells them, "Thank you for sharing your friends and your family with me," then looks at Ethan: "You've really changed my life."

They have only been sitting in mournful silence a split-second before Sutton opens the porch door and enters the room with a smug smile on her face. "Well isn't this cozy?" She sees the horrified looks on their faces and asks snidely, "I'm sorry. Have I come at a bad time?" They stand and look at her, in stunned disbelief, as a devilish smile lights on her face.
