Ian mentions that he "made" Jill's dog, and she starts to get her first pang of "huh?" about him. Then she finds her phone, screen cracked and dead on the kitchen table. She's got some thinking to do about creepy neighbor. So as she stands on the deck, looking at the horizon, Tall Boy appears behind her from a side door. Jesus, look behind you, Jill!
Jill gets an odd feeling and circles the house. She does not find Tall Boy, but instead opens a cabinet that contains a miniature version of her dog. Is this the stuffed doll she had as a child? Something else? Jill gets the heebie-jeebies. She is beginning to realize that her creepy neighbor is creepy.
Jill asks to go home, so Ian takes her back. As they pull into his driveway, they both notice someone in his house. It's Tom, and he quickly confronts Ian about his stash of Jill stuff. She gets it, and says to Ian: "I know who you are." Creepy neighbor = creepy half-brother.
Ian admits to being her half-brother, and says that everything he has done is for Jill. He's super eager and excited to show them what's in the garage. Great! What is it? Oh, dead dad being nibbled on by lots of dogs. Gag.
Ian does not fight -- and waves off Tall Boy -- choosing instead to confess to police. He takes the blame for all of the murders. Why is there a lingering fear? Is he still up to something? He does not break eye contact with Jill as he confesses and is led away.
Tom chooses this moment to say that he wants a family with Jill. Seems like a good time, right? She probably agrees because they start making out. Nothing like your dad's corpse and a psycho half-brother to get things going.
And yep, creepy Ian made it all happen. Blood-stained and smiling, he walks away from the scene and back to Jill's house. He's greeted by Tom who tells him to stay away, so he has Tall Boy kill the cop nearby to demonstrate his power. Oh My God. Can he be stopped?
