Rich

Rich is a man who had a lesion in his brain that caused an increase in his sex drive.

History
Rich and his wife, Lori, were in couples counseling. Lori said that Rich had suddenly started wanting sex all the time, more than a normal fluctuation. She worried about their daughter, Whitney, because Rich had started looking at her weirdly and going into the bathroom while she was showering. He admitted that he had sexual feelings about his daughter and he couldn't control them. He'd never touched her, but she was scared of him. When Rich confessed that, Lori said she wanted him out of the house, saying he was a monster. Rich started seizing in Sheldon's office.

An EEG showed a lesion on Rich's brain that was causing the seizures and the hypersexuality and lack of impulse control. Amelia said she could operate and remove the lesion, which would relieve him of the symptoms. Despite the risks, Rich decided he wanted the surgery because he didn't want to be a danger to Whitney.

Before Rich's surgery, he asked Amelia to kill him if she couldn't get all the lesion.

After surgery, Amelia told Rich she'd gotten the whole lesion, but he'd need time to recover fully. During that time, he would continue to see Sheldon and Whitney would continue to see Violet. He wouldn't be able to go home until they agreed that that's what was best for his family. Lori and Whitney visited him in his hospital room and he promised Whitney he'd do everything he could to earn back her trust and he hoped it was possible. Whitney and Lori then left the room without saying anything. Violet told Rich that Whitney was brave and hopeful.

Familial
