Later, Madsen goes to wash Lucy's blood off her skin in some unidentified bathroom somewhere. She has a minor freakout and slaps the towel dispenser a bit. Take that, towel dispenser! At the hospital, Soto tells Hauser that Lucy is in a coma. Hauser makes pained faces. He goes off to the Hole in the Woods to ask Jack Sylvane if Lucy was a target. Jack says he doesn't know, so Hauser makes some ominous mention of a "Dr. Beauregard" being able to jog Jack's memory.
Alca-Hub. Soto and Madsen put their heads together to try to find Cobb. They noodle around the computers and find Lucy's database on the missing "63s." In 50 years nobody's found a pattern to Cobb's seemingly random killings, but Madsen looks at a map of his shootings and in a few seconds decides that the randomness is actually hiding his true victims. That is Smallville levels of awful, right there. She points out there there's always a teen girl among his victims. "Who's the 16-year-old in his life?" she wonders. Infodump from Soto: Cobb was an orphan and went looking for his birth mother when he was 20 and she rejected him.
To solve the mystery, Madsen tries to get into Cobb's head by sitting in his old cell with his belongings. Soto brings her a letter from an Eloise Monroe that was never delivered to Cobb. It turns out she was his little sister and she wanted to apologize for their mother being unkind. Soto and Madsen figure Cobb was pissed that his little sister got to be raised by their mother. Eloise died in a car accident, so with her off the list they don't know who Cobb might be going after next.
