Dr. White is on the phone with Cat's principal as Cat sits across from him. He thanks the principal for not suspending Cat and then lies and says he has to respond to a medical emergency. He gets off the phone and tells Cat she has to stop bullying her friends and she tells him, they bully each other as a joke. He asks her if she is taking her Xanax and tells her he wants her to stay away from Bennett. He tells her he isn't going to ground her and she needs to try harder and she says she hates him. As Dr. White drives Cat to Sofia's he gets angry with her when she won't get off of her phone. He asks her not to use her phone for five minutes and speeds off after dropping her off and trying to take the phone away from her. Cat calls him and leaves a message. He goes to Alex Cox's house and after Sofia opens the door, Dr. White bursts in. He goes looking for Cat and then threatens Sofia and the others, and tells them they only care about themselves and should be institutionalized. He grabs a knife and Ava runs off. After threatening Sofia and the others, Dr. White leaves. Alex is going to her Alcoholics Anonymous meeting when Dr. White shows up and tells her, Cat is missing. He threatens to press charges and he suggests she is a mess and should kill herself. He calls Cat's number and demands she call him back and starts knocking over dead trees to build a trap for her while screaming into the woods. Sam is looking for the key to the room holding her and the others cell phones when she is attacked. She is saved when Dr. White bangs on the window and her attacker runs away. Sam finds Georgie's body and Dr. White runs to Sam. He calls 911 and Dr. White apologizes to Sam and tells her he didn't think Cat would hurt anyone and is then shot dead by Sofia.
