|“|| Nick: If I help you...can you bring back my family?
Lucifer: I'm sorry. I can't. But I can give you the next best thing. God did this to you, Nick. And I can give you justice. Peace.
Nick was a solemn and lugubrious widower who lived in Delaware who became the primary vessel of Lucifer until he possessed Sam Winchester instead. Several years later, Nick's body was restored and improved by Crowley to act as Lucifer's vessel once more.
Nick was married to a woman named Sarah, and together they had a child. One night, a criminal crept into their house and murdered Sarah and the baby in their beds. After the home invasion, Nick still resided in the house, and kept some objects that were connected to Sarah and the baby.
In Sympathy for the Devil, Nick started hallucinating Sarah and his baby, and their blood. Lucifer appeared as his wife Sarah and told him that he was a vessel, and that Lucifer wanted his consent to possess him. Nick, believing it was a dream yet doubting it was, nonchalantly refused. Lucifer told him that he was misunderstood, that he was punished for "loving God too much". He promised Nick justice for his family. Nick consented to possession.
In Abandon All Hope..., Nick's body began to develop burn-like sores from containing Lucifer's essence. When Castiel mentioned the sores appearing on his vessel's face, Lucifer admitted that Nick was "wearing a bit thin."
In Swan Song, Dean and Sam met up with Lucifer at an abandoned apartment in Detroit. Nick's body had degraded even further from the immensity of Lucifer's essence. Sam agreed to be Lucifer's vessel, and Lucifer then left Nick and entered Sam, leaving Nick dead on the floor next to the dead vessels of Lucifer's Guards.
In Meet the New Boss, Sam starts hallucinating and sees Lucifer, in the guise of his vessel Nick, without the burn marks. The hallucination retains the form of Nick throughout its appearances.
In Family Feud, Crowley reveals to Lucifer that his demons found Nick's body a few years before and repaired and improved it so it would be "a fitting final home" for Lucifer. When Rowena MacLeod had cast Lucifer back into the Cage, Crowley perverted the spell so instead Lucifer was sent into Nick's body. Lucifer thanks Crowley, but wonders how Crowley really expects it to end.
In Somewhere Between Heaven and Hell, Lucifer briefly escapes his chains only to have Crowley reveal that Nick is his true prison, Crowley having warded Nick's body based on Lucifer's Cage to restrain him while the chains were just ornamental.
In The British Invasion, Drexel examines Nick's body for Lucifer and tells him that the repairs to Nick's body are complete and he is a sound vessel for Lucifer. However, Drexel is unable to remove Crowley's "security system." On Lucifer's command, he promises to try.
In There's Something About Mary, Drexel continues his work on removing Crowley's security system from Nick's body. While he is unable to remove it, Drexel's efforts cause it to power up in reverse, giving Lucifer control over Crowley's vessel. With this, Lucifer is able to make Crowley's vessel unconsciously mimic his own movements in Nick. After apparently killing Crowley, Lucifer is free upon the Earth once more with Nick as his permanent vessel. Once Lucifer has his freedom, he changes Nick's wardrobe slightly, now donning a black leather jacket rather than his usual outfit in Nick's form.
In All Along the Watchtower, Sam shows Dean and Mary the picture of Lucifer outside Crowley's lair. Sam notes that its definitely Lucifer as he recognizes Nick as Lucifer's vessel. While confused as to how its possible, Sam correctly surmises that Crowley is responsible.
Nick has messy, short blond hair and light blue eyes. He is six feet and one inches tall, making him shorter than Lucifer's true vessel, Sam Winchester, by three inches.
His usual attire consists of a green T-shirt, a dark green shirt hanging loose, blue jeans and dark shoes. Although he was wearing a white shirt and sweatpants when he assented to possession, Lucifer changed into this attire and continued to use Nick's guise when not occupying a vessel.
When Lucifer took off his shirt, Nick was revealed to be a well-built man.
Nick's wedding ring is also worn by Lucifer.
After breaking free of Crowley's control, Lucifer dons a brown leather jacket.
