Tear Jerker / Prisoners

• Keller is brought to the police station to help Detective Loki identify articles of clothing that were found at Bob Taylor's house. He can barely bring himself to look at the pictures of the clothes, afraid that he might find something that belongs to Anna... and then he sees a picture of Anna's bloodied sock. Keller breaks down into Broken Tears as he confirms to Loki that the sock belongs to his daughter, then he calmly but coldly accuses Loki of letting Anna die by wasting time following Keller around. Loki doesn't have a good time of it either. While he doesn't see eye-to-eye with Keller most of the time, he takes no pleasure in having to show him the pictures and offers no reply to Keller's accusations, clearly agreeing with Keller about his failure. Part of the reason why he starts beating Bob Taylor in the interrogation room later on might be driven by his frustration over having failed the Dovers and the Birches.
• Before Keller is brought into the office, Franklin and Nancy are seen leaving the same office in a state of despair and sorrow, not even acknowledging Keller's presence. Loki confirms that they identified two articles of clothing that belonged to Joy.
• Throughout the movie, the Dover and Birch families' friendship unravels from the strain of the girls' disappearance. If Keller ever returns, that friendship will never be the same.
• Alex Jones's and Bob Taylor's life stories.
  • Kidnapped at the age of four, Alex Jones spent nearly his whole life being isolated, drugged, and tortured by a psychopath. The chance of his ever having a functional life had been stolen from him. And he was the luckier one of the two because unlike Bob Taylor, he did get to go home (in a sense, though he'd probably be institutionalized for a long time afterwards).
  • Bob Taylor's death, inadvertently brought on by Loki violently accosting him and demanding answers. As several other cops enter the room to pull Loki off of Bob, Bob steals one of the cops' guns in the heat of the moment, and Loki realizes too late that Bob isn't going to use the gun on them. His death is made more grim by the fact that he was another victim, having been abducted by a child, and the police's conclusion that he wasn't even involved with the disappearances. Before Bob kills himself, you can see him mouthing "It's okay" to the cops, trying to communicate that he isn't going to hurt them.
