Gregson's office. Holmes says everything in Victor's place was lined up on the left side. And there were blue marks on the ceiling above his bed, suggesting that he was throwing a ball at it. Anyway, the point is that he's blind in the right eye. He can't even pour orange juice without spilling it, so how's he going to hit a moving target at night? And the cigarette butts across the street were ground out in an ashtray, not flattened by being stepped on. So who framed him? Holmes says Crewes is the obvious choice, since he's the one who would benefit by someone new being blamed for these killings. And Crewes had access to all the files, so he could easily locate the same guy Holmes settled on. Bell asks who'd be willing to kill five people to get Crewes out of prison. Gregson says if they don't get someone soon, Victor will eat the charges and Wade Crewes will get out. Um, even if the police don't think Victor did it? And wouldn't they need to arrest Victor for the actual murders that Crewes is in jail for?

Brownstone. Watson says Crewes has had no visitors. Holmes says his only cellmate has life without parole. And he's from a group home, so he has no family. That last one seems like a stretch to me. Even people in group homes have people they grow up with, right? On the television, Crewes is having a press conference where he quotes Oscar Wilde. And Tolstoy. Holmes and Watson decide that he's reading at an advanced level, so someone must have taught him to read. There's no record of him taking any classes, but he worked at the prison library. And Holmes knows that the library at Sing Sing was on the verge of being shut down. A volunteer advocacy group called "LIFA" kept it open and he remembers that the son of Carla Figueroa was wearing a shirt with their logo.

Sean Figueroa is at LIFA headquarters, reshelving books. Holmes asks if Sean ever wondered why he had blue eyes. He goes straight to telling him that Wade Crewes was his father. Sean answers, "I don't know what you're talking about. I'm busy, so..." Now, when I say he's reshelving books, I mean he's moving them from one shelf to the shelf immediately above it. This scene reminds me a lot of a routine on John Mulaney's first album. Holmes continues the explanation about the prison library and points out that it'll be easy to establish paternity. Sean cops to being Crewes's son, explaining that he found his mother's diaries. He admits to teaching Wade to read and Holmes asks how loyal he thinks his father will be when the police offer him a deal. "Will he visit you in prison?" Suddenly Sean looks like he's reconsidering.
