The panic room scene was improvised. Director Kevin Alejandro just gave Tom Ellis and Lauren German some general directions, and the cameras started rolling while they did whatever felt natural to their characters while standing and holding each other.
This has a few nods to the movie "Ghost" with Patrick Swayze. First, when Dan tries and succeeds as a ghost to touch the TV volume button at the store. Secondly, when he jumps into LeMac at the same store, and also in the panic room when Lucifer and Chloe are embracing, you can hear the song "Unchained Melody" playing which played during the pottery scene with Patrick and Demi in Ghost.
The rallying cry of "Team Free Will!" is also heavily featured in Supernatural (2005), a show that has its own demons, angels, God, and Lucifer, wholly different from the comic-book character versions used in this show.
The episode title is said by Maze and Chloe, although Chloe said it as part of a sentence.
