When “Return To Murder House” airs on FX, Madison (Emma Roberts) and Behold (Billy Porter) will arrive at the home where Langdon (Cody Fern) was conceived to learn all about his past.

Check out the 4 things you can expect to see on “American Horror Story” Season 8, episode 6.

1. Murder House Crossover

In the “Return To Murder House” promo video, Behold tells Madison the spirits in the home don’t want to talk to them and they will have to use magic to force them out of hiding. Will Madison and Behold find the answers they are looking for? Or will they be forced to extend their stay in order to gain enough evidence against Langdon?

2. Langdon’s Back Story

In the “American Horror Story: Apocalypse,” episode 6 promo video, someone is seen creeping into the bedroom of a sleeping man with a knife. Later on, Langdon appears to be horrified as tears stream down his face. Will viewers witness Langdon commit murder? In the previous episode, Ms. Mead (Kathy Bates) revealed Grand Chancellor Ariel (Jon Jon Briones) wanted to help them dethrone Cordelia (Sarah Paulson) as Supreme, but she warned the teen not to speak about his father, Tate (Evan Peters). What other secrets could Langdon be hiding?

3. What Really Happened To Constance Langdon

Elsewhere in the FX promo video, Constance (Jessica Lange) begins to descend the staircase while asking Madison and Behold to identify themselves.
