Dynasty, 9 PM on Ch. 26:

Culhane (Robert C. Riley) makes some surprising choices when production on Liam’s (Adam Huber) movie doesn’t quite go as expected in the new episode “Mind Your Own Business.” Elsewhere, Blake (Grant Show) offers to help when Sam (Rafael de la Fuente) wants to celebrate some good news, and Jeff (Sam Adegoke) looks to an unexpected source for assistance. Fallon (Elizabeth Gillies) seeks business help from Alexis and Dominique (Elaine Hendrix, Michael Michele), which goes about as well as you’d expect.
