'Mad Jack' takes place at a scrapyard. When the player arrives, Jack is working on a bulldozer. The player can choose to go up and speak to him directly, or go into his garage, the latter making Jack angry. Inside of Jack's garage, there are cars, some tools, Jack's room, and if the player uses ARI to discover it, a skull in the acid bath. Inside of the garage, ARI detects many different pieces of evidence, including the killer's car tracks and paint, orchid pollen, a blood trail, and Mad Jack's finger prints among others. These clues will confirm that the killer's car came through, or otherwise lead Norman to discover that Jack is guilty of murder. Either choice results in the same outcome, but different dialogue.After
This is one of only two scenes where Jayden must take (or attempt to take) his drug. There isn't a resist choice here, though if the player fails to take the drug this could be seen as resisting. It can be assumed that Jayden has no choice, as he is dealing with a criminal and needs to arrest Jack, so he quickly gets his fix instead of trying to resist. When Jayden first notices he's starting to suffer from withdraw when Jack is held at gunpoint, Jack laughs at Jayden and comments on how the FBI are letting 'dopeheads' in.
This scene can play out a number of ways. After a struggle with Mad Jack, if the player hits all or most of the successful prompts, the player will have Jack at gunpoint instead. The player gets many dialogue choices, one of which is to 'impress' Jack, by shooting near him. Jack freaks out and starts confessing, though this is not the only way to get Jack to confess. Another known way is to talk to him for a bit, and then comment on the gasoline cans. Jayden claims they will "light up real nice" if he shoots them. This scares Jack into talking. After hearing Jack Confess, Jayden starts telling Jack his rights. It is here that Norman suffers from withdraw of Triptocaine, the drug he is addicted to. The player then has to attempt to take the drug, in the process holding down several, close to all, of the buttons. If successful (which is quite hard to do), Jack is arrested and taken into custody, and the scene ends there.
However, if the player fails, Jayden drops his drug and falls to the ground, where Mad Jack tells him he is going to kill him just as Jayden blacks out. When Jayden awakens, he is handcuffed to the steering wheel of his car, which is being taken by the bulldozer toward the crusher. Jayden struggles with his handcuffs, and then remembers the gun in the glovebox. If the player can get the gun to Jayden in time, he will shoot off his handcuffs just as the car drops into the crusher.
