Nick

"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: ...Then yes."

- Nick and Lucifer

Nick is a solemn and lugubrious widower from Delaware who became Lucifer's primary vessel until he possessed Sam Winchester instead. Several years later, Nick was resurrected and his body was restored and improved by Crowley to act as Lucifer's vessel once more, but a permanent one. This lasted until Lucifer's death at the hands of Dean Winchester which restored Nick back to himself.

Following the weeks of Lucifer's demise, Nick struggle with trying to be a normal person again as he was tended to by the Winchesters and friends. Recalling his grief, Nick would try to solve his family's murder but get nowhere and soon confronted his old neighbor Arty who seemed to know more than he let on. Nick ended up killing Arty, which showed the damage to his psyche by Lucifer had remained.

Early Life
Nick was married to a woman named Sarah, and together they had a son named Teddy. One night, a criminal crept into their house and murdered Sarah and the baby in their beds. Though Nick's neighbor Arty Nielson claimed to have seen someone running from the house, the murders were never solved as Arty changed his story. After the home invasion, Nick still resided in the house, and kept some objects that were connected to Sarah and the baby.

Season 5
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 The Song Remains the Same, when Anna Milton suggested that killing Sam would be a way of stopping Lucifer since it would deprive Lucifer of a vessel, Castiel pointed out that Lucifer already had a vessel. Anna's response was to ask if Castiel meant "that guy Nick" and pointed out that Nick was "burning away as we speak." As a result, Anna stated that Sam was the only vessel of Lucifer's that mattered.

In Hammer of the Gods, Nick's body had deteriorated further under the effort of containing Lucifer and massacring the pagan gods.

In Two Minutes to Midnight, Castiel told Sam and Bobby Singer that Lucifer would have to have been drinking gallons of demon blood in order to help maintain the integrity of Nick's body.

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.

Season 7
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.

Season 11
In O Brother, Where Art Thou?, Lucifer manifests inside a cage in Limbo in the form of Nick despite having no vessel.

In Hell's Angel, Lucifer takes on Nick's form again when confronting Crowley inside Castiel's head.

In We Happy Few, while Amara extracts Lucifer from Castiel, Lucifer takes on the form of a transparent Nick overlapping Jimmy's body.

Season 12
In Stuck in the Middle (With You), while trapped within a small cage in Crowley's throne room, Lucifer manifests in the form of Nick.

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 Who We Are, moments before being killed by Jody Mills, Doctor Hess presents Sam with a file containing surveillance photos of Lucifer in Nick's body outside of Crowley's lair and informs him of Lucifer's escape.

In All Along the Watchtower, Sam shows Dean and Mary the pictures of Lucifer outside Crowley's lair. Sam notes that its definitely Lucifer as he recognizes Nick as Lucifer's old vessel. While confused as to how its possible that Lucifer is using Nick as a vessel again, Sam correctly surmises that Crowley is somehow responsible.

Season 13
In Let the Good Times Roll, Lucifer battles Dean who is now the vessel of the Apocalypse World Michael. At the end of the fight, Dean kills Lucifer with an archangel blade to the side, leaving Nick's body lying on the floor of a church surrounded by the burned imprints of Lucifer's wings.

Season 14
In Stranger in a Strange Land, three weeks after Lucifer's death, Sam visits Nick in the Men of Letters bunker dungeon which has been turned into a makeshift bedroom for him. For the first time, Nick has woken up without screaming from a nightmare and his wound from the archangel blade is healing. Sam speculates that because the blade is designed to kill the archangel inside of the vessel, it didn't harm Nick. Nick recognizes how weird the situation is for Sam and admits that he's glad Lucifer is dead. Though Nick experiences some flashes of his possession by Lucifer, he doesn't know much about Michael or his plans aside from the fact that Michael wants to "do it right this time."

In Gods and Monsters, Nick is visited by Castiel as he flashbacks of several of the things Lucifer did while possessing him, including killing Mercury and supposedly killing Gabriel at the Elysian Fields Hotel. Nick is unable to understand why he would let Lucifer in and Castiel explains that it was because of the murder of Nick's family. Nick recalls Lucifer's psychological torture to get him to say "yes" and is horrified by what it.

Later, Nick arrives in the bunker's main room, having researched the murder of his family and having discovered that the case is still unsolved despite there being a witness who subsequently recanted. Nick's behavior alarms Castiel, particularly when he snaps his fingers at Castiel in a Lucifer-like manner after being enraged. Castiel examines Nick and determines that while Lucifer is gone, he may have done more damage to Nick's psyche than they realized. Castiel admits to sympathizing with Nick, explaining his own history with his vessel Jimmy Novak. However, Nick sees Castiel as no better than Lucifer for what he did to Jimmy, leading Castiel to tell Nick that what happened to Jimmy and his family is the biggest regret of his long life.

In an attempt to solve the murders of his family and get revenge, Nick visits his old neighbor Arty Nielson who was the witness the night Nick's family died. Though Arty claims to know nothing, his nervous behavior causes Nick to suspect that someone got to Arty and he strangles him up against a wall, demanding answers. Nick subsequently beats Arty to death with a hammer, the same manner that his family was murdered in. After Arty's death, Nick stares at his blood splattered clothes in the mirror, lays down the bloody hammer and leaves in horror of his act.

In The Scar, Castiel tells the Winchesters that Nick left the bunker saying he had something personal to deal with and that he hasn't returned Castiel's phone calls since.

Personality
Due to the loss of his family, Nick has become a bitter and grief-ridden man. Lucifer was able to exploit this by showing Nick several hallucinations resembling his family's death, causing him to break down. Eventually, although Nick at first coldly told the Devil to stop bothering him, he quickly began to be convinced by Lucifer's condemnation of God and eventually agreed to be his vessel after Lucifer promised he could get him justice.

After being resurrected and freed from Lucifer's control, Nick feels a great deal of remorse for what his body was used by Lucifer for, looking tormented as visions of Lucifer's kills haunt him. He is initially confused by how Lucifer could get him to say "yes," but after realizing what happened, Nick is ashamed of how easily he was manipulated by Lucifer. Upon interacting with Castiel, Nick seemed distraught at how awkward Castiel was to him but after learning of how Castiel used Jimmy Novak, he was disgusted by what Castiel did, scornfully replying he is no better than Lucifer, although he genuinely reconsidered it after Castiel told him what happened to the Novaks was his greatest regret.

However, his long-time hosting of Lucifer has negatively affected Nick. He becomes more determined than ever to find justice for his family, even going as far as to brutally kill his neighbor who turned out to be the killer but did express horror at his act. He was frustrated at how his family's murder was never considered important enough to be solved by the police. He also showed some of Lucifer's tendencies when angered, angrily snapping his fingers in a heated moment with Castiel as if trying to kill him in the same way that Lucifer killed those who angered him, though Nick didn't remember doing it.

Physical Appearance
Nick has messy, short blond hair and light blue eyes. He is six feet and one inch 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.

Nick's wedding ring is also worn by Lucifer.

After breaking free of Crowley's control, Lucifer dons a brown leather jacket over a white shirt.

While trying to become a new God, Lucifer changes Nick's attire to a suit and tie and briefly, sunglasses which he quickly discards. Lucifer wears this outfit while exorcising Anthony, but later changes his clothes back to normal.

Over the course of his possession of Nick, Lucifer sports varying lengths of hair and scruff from short hair to slightly longer and little to no facial hair to significant scruff at the time of his death.

After Lucifer's death, Nick wears a white button-down shirt and jeans along with his wedding band. He also has some scruff.

Trivia
Nick
 * The name 'Nick' is possibly a reference to 'Old Nick', which is a nickname for the Devil.
 * When Lucifer is yanked from Castiel by the Darkness, his true form appears as Nick for a moment before he disappears.
 * Nick is the second vessel whose body is restored specifically for an angel to possess as his vessel. The other vessel is Jimmy Novak whose body was restored by God for Castiel's use. As revealed in Stranger in a Strange Land, Nick was actually resurrected to act as Lucifer's vessel unlike Jimmy who remains in Heaven.
 * The method Lucifer uses to approach Nick is later used on Vince Vincente. Both are subjected to blood that horrifies them, and meet with Lucifer who takes on the guise of their deceased lover or wife.
 * Given the alternate reality version of Michael's inability to recognize the main reality Lucifer along with several other angels, Nick was presumably not the vessel of the deceased alternate reality Lucifer. It is unknown who he used as Sam never existed in that world.
 * Nick is the first vessel to survive the destruction of the angel possessing them. Sam speculates that as the archangel blade was designed to kill archangels, it left Nick unharmed aside from the wound in his side where Dean fatally stabbed Lucifer.
 * Before Season 14's Stranger in a Strange Land it appeared that only Nick's body was restored to act as Lucifer's vessel. In Stranger in a Strange Land Nick himself is revealed to have been resurrected contrary to prior belief.
