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: How do I know you're telling the truth?
Lucifer: Because, contrary to popular belief, I don't lie. I don't need to. What I need... is you. Nick, I need you to say yes.
Nick is a solemn widower living in Delaware. He 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. After the home invasion, Nick still resides in the house, and has kept some objects that were connected to Sarah and the baby. Nick is used as a "Plan B" vessel for Lucifer. However, because he isn't the "true" vessel, over time Nick’s body slowly becomes more and more degraded. The longer he continues to be occupied by Lucifer the more his body suffers, due to the inability of Nick's body to handle Lucifer's essence. Castiel tells Sam that Nick would be drinking gallons of demon blood in order to be able to host Lucifer. Nick is dispossessed in 5.22 Swan Song, at which point he dies from being burned out by the possession. Despite no longer using Nick as a vessel, Nick appears to be Lucifer's favored form to manifest visually in as seen in 11.09 O Brother, Where Art Thou?, 11.10 The Devil in the Details and 11.18 Hell's Angel. Years after Nick's death, his body was found by Crowley's demons and it was repaired and improved so that Nick's body could be a suitable permanent vessel for Lucifer. Following Lucifer's defeat in 12.08 LOTUS, he was returned to Nick's body by a spell, causing Nick to once more become Lucifer's vessel.
Nick's wife and child have been murdered during a home invasion. As he grieves, he starts hallucinating. Lucifer appears as his wife Sarah and tells him that he is a vessel, and that Lucifer wants his consent to possess him. Lucifer says he is misunderstood, that he was punished for "loving God too much." He says that he will help Nick get justice for his family. Nick assents to possession.
While talking to Sam about him being his true vessel, Lucifer old him that Nick was an improvisation or a "Plan B."
Castiel told Sam that he would have to drink an enormous amount of demon blood before he could let Lucifer inside him when they were discussing Sam's plan on imprisoning him along with himself. All the while, mentioning that Nick is drinking gallons as they speak to continue to contain him as it can strengthen the vessel.
Dean and Sam meet up with Lucifer at an abandoned apartment. Nick's body looks even more run-down and degraded than it did in 5.19 Hammer of the Gods. Sam agrees to be Lucifer's vessel. Nick's body is seen motionless on the ground after the dispossession, burned out from Lucifer's possession.
A few years after Nick's apparent death, Crowley and his demons find his body and Crowley has it repaired and improved to act as a suitable permanent vessel for Lucifer. After Crowley corrupts Rowena's spell to send Lucifer back to the Cage, he is instead sent into Nick's body where Lucifer is restrained with chains made from the same material that was used to create the Cage which was discovered after a team of Crowley's twelve most trusted demons studied it. Due to Crowley's improvements upon Nick's body, he shows no signs of degrading from the possession like he did previously and like Lucifer's other vessels aside from Castiel and President Jefferson Rooney.
Crowley revealed that he not only improved Nick's body to act as a permanent vessel for Lucifer, he also had the runes and spell-work from the Cage carved into every molecule in order for Crowley to effectively torture him as well as rendering him powerless and preventing him from vacating his vessel.
A demon named Drexel was inspecting Nick's body to make certain that it and the security system are both completely intact. He was attempting to help Lucifer by shutting down the security system in Nick's body. Drexel told him that a demon named Spivak designed everything planted in Nick's body, however Crowley had him and the other eleven demons in the Cage Project killed to safeguard its secrets.
Drexel told Lucifer that the security system in Nick's body was beginning to power up in the opposite direction, giving Lucifer control over Crowley rather than vice versa. After showing off his newfound puppet-like abilities over Crowley's meatsuit, Lucifer powers himself up, possibly destroying the security system in Nick's body.
- The name "Nick" is possibly a reference to "Old Nick" which is a nickname for the Devil.
