TLT TV show but it’s a sitcom called Gideon’s Island and it’s about their wacky misadventures as they’re stranded in Canaan House.
Cytherea’s still there posing as “Dulcinea” and still trying to kill them all, but it’s played for laughs. Every episode ends with her dastardly plans getting foiled by chance.
The scene with Gideon laying facedown on the floor and moaning about being a homewrecker is, of course, basically unchanged.
