Barclay explains he was infatuated with Mary Foster because of her beautiful mind. When Foster began to complain of headaches, Barclay experimented on her. He thought he could help but ended up killing her.
Dr. Bates explains that he helped arrange for James Danby to be sentenced to the Toronto East Asylum after Danby killed his friend in a fight. In his attempt to be helpful he delivered Danby into Barclay's hands. Danby's mind proved equally fascinating until Barclay's experiments killed him as well.
After Mary Foster's death, Rebecca Foster had nowhere to go. Dr. Barclay forged a file that portrayed Rebecca as a potentially violent offender and thus had her committed to keep her close. Barclay hoped that Rebecca would one day develop into a genius even greater than her mother.
Barclay staged Danby's murder scene. He placed Dr. Bates' cricket bat to frame him but Rebecca stumbled upon the scene first and became incriminated herself.
Barclay tells Murdoch that he couldn't help but try to experiment on him. Barclay states that Murdoch's brain is among the most unique of all. Murdoch places Barclay under arrest.
Dr. Ogden informs Dr. Bates that he should tender his resignation. His brand of psychiatry is of no benefit to his patients. Ogden tells Rebecca that she may stay with her for as little or as long as she likes.
