* Nick being alive at the time of [[12.13 Family Feud]] makes it unclear how Lucifer was able to repossess him as it has been previously established that when an angel leaves their vessel, they need permission once again to reenter. At the time Lucifer reentered Nick, he was unconscious in a chair and did not appear to have consented. However, he may have been in a vegetative state, much like how [[Donnie Finnerman]] was shown to be catatonic in [[5.03 Free to Be You and Me]]. Angels also do not require verbal consent, as [[Gadreel]] was able to possess Sam through his subconscious.
* [[Mark Pellegrino]]'s name did not appear in the opening credits for [[14.01 Stranger in a Strange Land]], presumably to maintain the surprise of Nick's return. However, during the airing of the episode and before Nick appeared in person, a promo for the movie ''Halloween'' was aired featuring Sam asking Nick about [[Michael (Apocalypse World)|Michael]], thus ruining the surprise. Mark Pellegrino returned to the opening credits for [[14.02 Gods and Monsters]] for his role as Nick. The same thing happened with Mark's surprise appearance as Lucifer at the end of [[12.12 Stuck in the Middle (With You)]] with Mark then appearing in the opening credits for the very first time as a main cast member as Lucifer in the next episode [[12.13 Family Feud]].
* Nick is the second main character portrayed by [[Mark Pellegrino]], taking over which he took on after [[Lucifer]]'s death.
