American Horror Story: Apocalypse - 6 Ups & 1 Down From 'Boy Wonder'

2. Stevie Nicks & Gypsy

The last time Stevie Nicks was seen in the American Horror Story shared universe, she was serenading her fellow witches with Fleetwood Mac hit 'Seven Wonders' as they prepared to go and perform the Seven Wonders.

She makes a surprise return in Boy Wonder, which makes the spectacular episode even more, well, spectacular. Misty and Stevie reunite, and to make up for lost time, the singer serenades the swamp-witch with Fleetwood Mac tune 'Gypsy. It was odd that the show missed out on including the track in Coven considering how the lyrics couldn't be more relevant to the Misty character, so you could say that this special moment is literally 5 years in the making.

Nicks' initial appearance in AHS has gone down in TV history, and it wouldn't have felt right to re-visit Coven without the chanteuse.
