He leaves.That night, Max seals off the entrance to the peephole corridor by using a nail gun and planks of wood at the door, which we discover is in his wardrobe.The next scene shows Max with August, giving him his medication by syringe.

He then leaves.That night, she is preparing dinner while Max watches her through a peephole in her kitchen. She receives a text message and then goes to her bathroom to get ready. While there, Max comes into her home to check her phone, as he is there Jack and his dog come to the door, Max hides. The dog senses Max and starts barking at the kitchen cupboard. Jack and Juliet have dinner and they have a discussion about their break up. Jack tells her that she was never there and she asks him not to tell her he cheated because she works too hard. They have more of a discussion and then sleep with each other. Max is watching the whole thing from behind her two way full length mirror in the bathroom.Jack does not stay the night and leaves with the dog. Max pours something into the open bottle of wine from a syringe just as Juliet comes to pour herself another glass. Later on, Juliet is knocked out in her bed and her hand falls off the edge. Max is lying under her bed and starts licking her fingers.The next morning, Juliet sleeps in for work which she finds odd as she has never had a problem waking up before.
