"There is a lot going on with Derek," she said. "He's really taking up our emotional head space for a good chunk of this midseason stretch."

In fact a heavy weight has been enlisted to play Derek's father in the episode, titled Derek. TVLine recently revealed that Danny Glover will guest star as Derek's dad in an episode, titled Derek. Showrunner Erica Messer also weighed in on this starry addition for the episode. "It's an interesting role that he plays," Messer said. "The reason Derek needs to call on this protector in this moment and work through some things is really beautifully written by Breen Frazier, and directed by [cast member] Thomas Gibson."
