Escape from the Happy Place

S4 E5: Eliot is living through an amazing loop of mellow fun back on campus at Brakebills. But that persistent knocking at the door reveals that someone is trying to get in. That someone turns out to be Charlton, the man that The Monster had possessed before he was inside of Eliot. He tells Eliot that he can communicate with his friends if he can find a door in his own worst memories. He tasks Eliot with figuring: what does he not want to think about? He needs to find it in order to find the door.
