A brief recap of The Institute season 1 episode 4

In The Institute season 1 episode 4, Luke undergoes the Dream Box test and sees images of his parents, along with a series of disturbing images that leave him shaken. The facility welcomes new kids — twin girls, Greta and Gerda, and a teenage boy, Harry. However, Harry ends up killing one of the twins after experiencing side effects from the drugs.
Luke's telepathic powers grow to the point that he predicts Harry's fatal attack on Greta. Hendricks and Tony put him through a grueling experiment to get him to admit that he's TP now, but he doesn't give in. Additionally, Luke and Avery connect with Kalisha in the Back Half and learn about the recovery room, where the humming sound seems to originate.
By the end of the episode, Avery uncovers what happens inside the room by reading Maureen's thoughts. Elsewhere in town, Tim investigates Annie's death, convinced she was murdered. He visits the Red Steps looking for answers, as Annie believed that the teenagers who drowned there years ago were actually killed as part of a conspiracy involving the Institute.
