Joe, relentlessly upbeat and overly talkative, soon cracks through Fin's reserve. The two begin to take daily walks along the tracks, and after Olivia gives Fin a movie camera, Joe drives alongside a passing train so that Fin can film it. Joe and Fin sleep over at Olivia's house after watching the footage and the next morning a flustered, unannounced David is greeted by the two of them. The three forge a tentative friendship that is threatened when Olivia descends into a deep depression, disappearing from the town. Meanwhile, Emily seeks solace in Fin, who slowly is realizing interaction with other humans may not be as unpleasant as he thought. Fin tries to protect Emily from her boyfriend at a bar, but he pushes Fin aside, causing Fin to lapse back into his asocial behavior. Emily later comes to apologize, and after she and Fin share a kiss, she spends the night with Fin. Cleo asks Fin if Olivia is coming back, to which he replies that he doesn't know. He decides to keep an eye on Olivia's house, but when he spots her fighting on the phone with David and he goes up on the porch, Olivia angrily tells him to leave. Fin spends the night drinking and, collapsing on the track, is passed over by a train, undamaged but for his pocket watch. As if feeling blessed by his gift of life (and symbolically upon his watch getting destroyed in the train mishap), Fin walks up to Olivia's home only to find she has attempted suicide. Olivia reveals that David is having another baby with a different woman. Fin takes care of Olivia's home while she recuperates in the hospital. Fin picks up the courage to talk to school kids about trains.
