**Warning: This article contains spoilers for episode 6 of ‘American Horror Story: Apocalypse’**

‘The Haunting of Hill House’ may be getting all the plaudits at the moment – and rightly so (even Stephen King is loving it) – but anthology series ‘American Horror Story’ has long reigned ‘Supreme’ when it comes to horror on the small screen.

The hit FX show is currently halfway through its eighth season, but episode 6 of Apocalypse – which aired on Wednesday night – featuring a crossover between series 1, Murder House and series 3, Coven, is the one that most fans have been waiting for.

And h-o-l-y smokes did it deliver; the 78 minute episode, literally called “Return to Murder House,” was directed by show star Sarah Paulson and saw the return of fan favourite Constance Langdon.

I won’t ruin it completely but the episode sees Madison and Behold Chablis return to Murder House to search for answers about their new Supreme Michael Langdon.

Constance and Billie Dean Howard confront them, where a voice croons: “Who do you think you are, coming in here, swanning around, spewing vulgarities?”

It’s at that point the blonde bombshell – who we’ve not seen since Freak Show – booms:

“I’m Constance Langdon, and this is my f**king house.”

It’s an iconic moment from a character we haven’t seen for the best part of four years.

As the episode unfolds we get the backstory of Michael’s troubled upbringing plus a number of ‘Murder House’ stars reprising their roles.

As you’d expect, Twitter pretty much went into meltdown:

As mentioned, the episode also marked the directorial debut for Sarah Paulson, which says a lot about her given it was such a success.

Ahead of the episode, show creator Ryan Murphy took to Twitter to announce that the cast would be live tweeting throughout the episode to celebrate Paulson’s achievement.

Speaking on her directorial debut, Sarah recently told The Hollywood Reporter:

“It’s always exciting and also terrifying when there’s a dynamic shift.

“I’ve been an actor on that show for many years and then all of a sudden, and I’m now in a position where these people who I work with are now going to have to, for lack of an articulate way of saying it, help execute my vision.”

American Horror Story: Apocalypse continues Wednesdays at 10/9c on FX.
