Rosie can also be heard saying, “Spence didn’t kill Peri, but I know who did.” Zoila is also seen as she cries to someone, “She’s this close to finding the real killer!”

The preview video also shows policemen raiding the Westmore house, while Kill Face escapes from prison and points a gun on someone. Elsewhere, Hugh is tied up by Carmen, Dani and Rosie. He wonders who they are and Carmen replies, “We’re maids, and we’re not messing around.”
