American Horror Story: NYC finally reveals Big Daddy's identity in devastating finale

When it became clear in episode 7 that the Mai Tai killer (played by Jeff Hiller) was only responsible for a small portion of the deaths and disappearances being investigated, all eyes turned to Big Daddy.

At it, Sam (Zachary Quinto) faints, and he's forced to reckon with all the people he's hurt and those who have hurt him in a very A Christmas Carol-esque sequence that ultimately ends with him running from Big Daddy on a beach, as Denis O'Hare's Henry tells him that his efforts are futile, and he needs to surrender.

He's also not the actor who has played Big Daddy all season, Matthew William Bishop.

Regardless, the Big Daddy we've all come to know and dread returns for the rest of the finale's run time, as he watches over Patrick's (Russell Tovey) death in 1987, and appears in Hannah's (Billie Lourd) apartment after Adam (Charlie Carver) learns that his friend and mother of his child has succumbed to the virus as well.
