Pretty much the entire movie counts as this, with a large dosage of Nightmare Fuel, on a count of it being a slow and painful exploration of a day in the life of a man stricken with post-traumatic stress disorder. However, some notable moments include:
- The scenes of Joe casually contemplating suicide through harmful gestures such as sticking a knife in his mouth, dropping it on the floor and barely dodging it before the blade can cut his foot, and him suffocating himself with a plastic bag. Also counts as Nightmare and Paranoia Fuel.
- Joe's flashbacks including his time in the military, where he watched an innocent child get shot just as soon as he offers him a candy bar, his time in the FBI, where he discovers an entire cargo crate full of dead teenage girls, and the abuse he received at the hands of his father. Definite Nightmare Fuel as well.
- Moments after rescuing Nina, the poor girl has a small breakdown and hugs Joe, who does his best to comfort her and reassure her everything is okay. Sadly it is not.
- Joe discovering his mother's dead body. Even after he's killed the guards who've killed her, all he can do is lay beside one of the dying hitmen and contemplate every horrible thing that's been happening.
- The underwater burial of Joe's mom, which nearly culminates in another suicide attempt by Joe in which he nearly drowns himself. However, it becomes a Heartwarming Moment and Moment of Awesome when he sees a vision of Nina and gets the motivation to go rescue her.
- Joe's breakdown in the midst of rescuing Nina for the second time. It's at this moment that we realize his stoicism has its limits.
- The final scene, in which it appears that Joe has finally committed suicide. Even though it's revealed only seconds later that it was just another violent fantasy, it's left ambiguous whether his mental health ever recovers, even after rescuing Nina and taking her in as his own.
