The Patient - S1.E3

A doctor's work with a patient suffering from a paralyzing disease yields unusual results - the patient can suddenly communicate through his computer. The patient soon displays unusual abilities and knowledge. When Paul investigates he meets with the doctor's daughter and the two start to become close. Alva soon determines the patient is possessed by a entity, but it's already taunting Paul and the doctor, and convinces the doctor knock out Paul and give other patients an overdose. Alva shuts down the patient's life support long enough to drive the entity out and Paul stops the doctor...who reveals his daughter died of the same disease two years ago.
