Hub. Rebecca and Doc go through the victims' credit card records. Purchases place them both at a fundraiser for the San Francisco Philharmonic on the same night. At the same time, Hauser calls them from the concert hall to tell them about Porter working there. He texts them Porter's home address.
Hauser and Rebecca meet outside Porter's apartment. When no one answers the door, Rebecca picks the lock. The apartment is tidy, but obviously lived-in, with dishes and knickknacks on the table. Doc shows up out of nowhere. "They're renting apartments now?" he asks. "The landlord says he's been here for months," Rebecca says. Hauser finds four frayed bows and realizes why Porter's been taking his victims' hair. There's no reason for him to have that many bows lying around except for the discovering of them. Two are strung with blond hair, two with black. (Human hair would make crappy bows, in case any psychos out there were thinking of trying it.) Hauser finds a fifth bow, this one with red hair. "He's got another girl," Rebecca says.
That girl is currently lying tied up in her bed somewhere, half her hair lopped off. He mopes about not getting the gig of his dreams, then has a flashback. Accompanied by guards, Porter and Lucy take an evening stroll around the yard. She delivers the "good news" that he'll soon be back in general population. He'll even be allowed to keep the violin and play at night. "Why are you doing all this for me?" he asks, genuinely touched. "Because I believe a man can change," she says. He thanks her. "Maybe one day I'll be able to repay the favor."
Hub. The team goes over photos of all the female guests at the fundraiser, narrowing their choices to the redheads and then settle on the one who hasn't posted on her Facebook-like page recently. They find her tied up but still alive. She tells them that Porter told her he auditioned, they said yes, and he's playing for the first time that night. So, not only is he a psycho murderer, but a liar, too!
He plays for an empty audience in the concert hall. Such is the power of his delusion that he can hear effusive applause as he finishes.
Flashback. Warden James accompanies Porter to his cell, much to the audible dismay of the other prisoners in general population. They shout and moan and plead with the Warden, but politely refrain from using curse words. As Porter is sealed into his cell, he takes out his violin and begins to play. The angry protests quiet down. The camera moves down the cell block, showing some of our past prisoners of the week as they enjoy the serenade. Come back, Jack Sylvane! Tiller, Beauregard and Lucy watch the transformation from the other end of the cell block. Beauregard is impressed. Tiller is unmoved. "The Warden's got himself a new toy," Dr. Beauregard says. "Mr. Porter is not a toy," Lucy says. Dr. Beauregard chuckles. "I was talking about you." Lucy makes a worried face.
