|“|| ARE YOU PREPARED TO GIVE YOUR LIFE TO SAVE YOUR SON'S?
- The final trial
If Ethan has not been imprisoned, he makes his way down a red hallway into an elegant white room filled with mirrors and cameras and a vial, a stopwatch, and a media player on a table. The media player informs Ethan that the poison in the vial will kill him in one hour, but he will get the last letters of the address if he drinks it. After deciding whether or not to drink the poison, he will either drive to the address at which Shaun is being held or have to guess at the address based on the information he's collected.
- Main article: /Walkthrough
- Completion of all 5 trials: Ethan will find Shaun.
- Completion of 3-4 trials: Ethan must guess Shaun's location from available information.
- Completion of fewer than 3 trials: Ethan will fail to find Shaun's location, though if Madison survives "Killer's Place" and found the address in the computer she can give it to Ethan.
With the history of rats as carriers of disease the poison may refer to their role as disease vectors. The room is also synonymous with this, the corridor representing blood and the main room representing cleanliness. Alternately, the fact that rats have been poisoned for centuries but continue to survive and thrive may also point to the ineffectiveness of the poison.
- Sacrifice – Drink the poison.
- Clever Dad – Work out where Shaun is being held.
- Trial Master – Complete all five of Ethan's trials successfully.
- Since poison can affect people differently depending on their weight, metabolism, overall health, and several other factors, the Origami Killer would have found it nearly impossible to choose a poison that would kill Ethan and other fathers in exactly one hour. The precise time frame may serve as a hint that the drink isn't actually poisonous and is part of a test.
