404 Not Found (Mr. Robot)

A Dark Army agent overhears the conversation between Elliot (Rami Malek) and Tyrell (Martin Wallström) from the white van. As he prepares to ambush them, he is knocked unconscious by Tyrell with a hammer. After the man dies, they decide to escape in his van. When Elliot fails to show up at Allsafe, Darlene (Carly Chaikin) goes to his apartment, discovering his note and decides to track his location.

Elliot and Tyrell go to a gas station, intending to burn the body. However, while they are inside the station, they discover that the van has disappeared. As there is no service in the area, they are forced to leave through the woods to a nearby town, but they end up getting lost. As Elliot and Tyrell clash over their lifestyles, they realize they have returned to the gas station. Darlene tries to hijack a car, but is confronted by the car's owner, a drunk man named Tobias (Jon Glaser) wearing a Santa Claus costume. Tobias agrees to let her take his car if she drives him home, since he is drunk. Alone on Christmas Eve, Dominique (Grace Gummer) gets into a sex chat group, where she decides to invite a female user, Happyhardonhenry806, to come over.

While driving, Darlene learns more about Tobias. He is a children's hospital volunteer, seemingly depressed from the nature of his volunteer work, and he alludes to an accident involving his wife. As he is carrying both liquor and Percocet, Darlene suspects he intends to commit suicide. As they arrive at his house, they see Tobias' car already parked in the driveway, and realize that Darlene has inadvertently stolen someone else's car. Not wanting to leave leave him alone, Darlene confronts him on his behavior. Tobias explains that his wife is alive and well, having merely hurt her back while decorating their house together, hence the Percocet; he does not want to commit suicide, his previous statements having been misinterpreted by Darlene. When Tobias surmises that Darlene may herself be in need of help, she shares that she is concerned about her brother Elliot's safety as he is the only family she has left. He listens, and says that he hopes her brother is safe. As the drunken Tobias returns inside and is greeted by his wife, Darlene leaves to search for Elliot, but is forced to pullover on the side of the road when she has a panic attack.

Dominique welcomes the woman (Roberta Colindrez), but gets panicked when they kiss. When she goes to the bathroom, the woman enters wearing a Dark Army mask and starts drowning her. Dominique suddenly wakes up, revealing that the encounter was a nightmare.

When Christmas officially arrives, Elliot and Tyrell have another argument, in which Tyrell accuses Elliot of not caring for him, which he concedes. Elliot prepares to leave Tyrell, feeling he doesn't need him. As Mr. Robot (Christian Slater) talks about loneliness, Elliot returns. He proclaims that only cares for Darlene's safety, but does not want to abandon Tyrell. They continue walking, finding that the van killed a deer on the road. As they inspect the van, the Dark Army agent shoots at them from inside before killing himself. However, Tyrell is revealed to have been shot. He refuses Elliot's attempt in taking him to a hospital, and instructs him to burn the van and take care of Whiterose before walking away. Tyrell continues walking until he finds something shining in the ground, as the screen fades to white.
