The following is a list of characters that have appeared in the A&E drama-thriller television series Bates Motel, an adaptation of Robert Bloch's novel Psycho.
As the series progresses, it becomes clear that Norman is mentally ill: he experiences blackouts, during which he hallucinates visions of Norma and behaves violently, before coming to with no recollection of his actions.
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 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.
Although Emma is British, having been born in Manchester (as was Cooke, in real life), she was brought up in the United States and speaks with the local dialect.
Identifying with his unusual personality, troubled history and friendly nature, Emma is immediately infatuated with Norman and develops a friendship with him.
Seeing this, Norma becomes fond of her and employs Emma at the motel to keep her close to Norman, as well as to provide her with some much-needed maternal support and advice.
In addition, she becomes upset when Norma begins to blatantly keep secrets from her or tell her false stories to explain some of Norman's strange actions, and contemplates resigning from the motel.
Norman ultimately reaffirms his loyalty to her when he angrily berates his girlfriend, Cody, for egging Emma to do a cliff jump into a lake, clogging her airway and nearly killing her.
She soon grows close to Dylan, who becomes concerned when he learns that Emma's health has deteriorated severely, and takes it upon himself to raise the money she needs for a lung transplant.
Her world takes a turn for the worse, however, when her father is burned to death, and in her time of grief, she ends up having sex with Norman.
With blood on her hands, Bradley turns to Norman once more, and, with his help, flees White Pine Bay to go into hiding in Boston.
His interaction with the Bates family does not go smoothly, when he suspects Norma's complicity in the disappearance (and death) of Keith Summers, his friend and the former motel owner.
Caleb Calhoun (portrayed by Kenny Johnson)[7] is Norma's estranged older brother, Norman's uncle and Dylan's biological father.
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.
