List of Bates Motel characters <=SEP=> Dylan Massett (portrayed by Max Thieriot)[3] is Norma's estranged son and Norman's half-brother. Having grown up largely on his own, he is resourceful, strong-willed and independent. He genuinely cares about Norman, but has a difficult relationship with Norma. He believes that Norma seeks out conflict and drama, and that her treatment of Norman will damage him. When he arrives to White Pine Bay, after recently being laid off, Dylan bonds with Norman and encourages him to have a life outside of Norma. He gets involved in the town's illicit marijuana business, and quickly rises up the ranks as he wins favor with his superiors. His world comes crashing down, however, when he learns from Norma that he is the product of an incestuous rape – his true father having been Norma's brother, Caleb – and distances himself from the family, moving out of the Bates' house. He eventually reconnects with his mother and brother in the second season finale. In season three, he becomes increasingly concerned with Norman's behavior, and tries to convince Norma to seek help for him. He also facilitates a reconciliation between Norma and Caleb after reconnecting with his father and starting a legal medicinal marijuana farm of his own, following a DEA raid which wipes out the town's cannabis trade. Throughout the season, he starts to grow close to Emma as she assists in looking after Norman, and attempts to raise the funds for her lung transplant, and the two subsequently form a romantic attachment. Dylan leaves for Seattle with Emma and the two subsequently get married and have a daughter. He finds out online that his mother committed suicide and is furious that Norman did not tell him. He returns to White Pine Bay after fearing for Norman's mental health. Norman later confesses to murder; Dylan visits Norman's hearing but is unable to listen to the charges against his brother. After Norman is freed, he goes to the motel and finds Norman in the kitchen with Norma's corpse. Norman attempts to stab Dylan but is fatally shot by his brother, whom he thanks as he passes away. Dylan then returns to Seattle to be with Emma and their daughter.

List of Bates Motel characters <=SEP=> Caleb Calhoun (portrayed by Kenny Johnson)[7] is Norma's estranged older brother, Norman's uncle and Dylan's biological father. In season two, Caleb arrives at the Bates Motel but Norma immediately throws him out. However, Caleb bonds with Dylan, saying he helped protect Norma from their abusive father when they were children. Dylan defends Caleb to Norma, but he also repeatedly raped her for years during their childhood. This then escalates into a fight between Norman and Dylan until Norma intervenes by revealing that Caleb is Dylan's father. After Norman (in Norma's persona) attacks him for the rape, Caleb leaves town. He returns to help Dylan with a "pot farm" by building a barn. Dylan grows closer to Caleb and ponders telling Norma about his return, which is hastened by Norman and Emma spotting Caleb at the remote cabin. Norma and Caleb have an emotional reunion in which he apologizes to her, but she does not completely forgive him. After a curious neighbor to the farm seeks a gun runner to Canada, Caleb offers to take the job; however, Dylan also needs the money to help Emma so he accompanies him. The dropoff is supposed to have been the neighbor's demise, and Caleb manages to save Dylan. He then returns to beat the neighbor until he promises to leave Dylan alone and give them the promised money. Caleb leaves again, but not before telling Norma about Norman attacking him in the "Mother" persona.
