Lana worries that Mary Eunice hasn't done anything about Dr. Thredson, but she discovers Kit has returned to the asylum. She explains to him that Thredson is the killer and she will prove Kit's innocence. He wants to help her, but can't yet as he's been drugged.

"Unholy Night" is written by co-executive producer James Wong and directed by Michael Lehmann.

In a December 2012 interview with Entertainment Weekly, series creator Ryan Murphy spoke about writing this episode with guest star Ian McShane in mind, "Christmas and American Horror Story do not go together and so we were trying to figure out 'What's our version of Christmas?' And the answer of course is a homicidal Santa. There's a whole subgenre in horror dedicated to these psycho Santas. It's a thing. So we decided let's write somebody who's so crazy they end up in Briarcliff. I had heard Ian McShane really loved American Horror Story. So we wrote it and we were like, 'Let's send it to him and ask for a quick pass.' To my delight, he said yes."^[2]

The critical consensus reads, ""Unholy Night" makes up for its transitional storyline and unanswered questions with a welcome return to the grotesque and a standout scary performance from new cast member Ian McShane."^[4] Chris Harnick of The Huffington Post stated he "was a little bit disappointed with this episode." He added, "[Ian] McShane's acting was exceptional, but I wanted a little more progression to the 3,000 plots that are currently going on."^[5] Matt Fowler of IGN called "Unholy Night" "just good, sick fun," adding, "It seems a bit slight to call this episode a fun romp, seeing as how bloody and unhinged it was, but watching McShane chew up the set and slash at people with glass tree-toppers was just gruesome enough to make me giddy."^[6]
