Layton corners a suspect: a Brakeman named LJ’s father (the father of the creepy, fanatical First Class girl, LJ Folger). Before he can get answers, Osweiller arrives not to help, but to silence. Osweiller slits the suspect’s throat in front of Layton, then calmly says: "Your investigation is over. The killer killed himself." Layton realizes the killer is likely someone inside
Meanwhile, (now revealed to the audience as the true, secret ruler of the train) is growing desperate. The train’s eternal engine is failing. She needs an engineer.
