Dexter extends a mysterious gathering as Harrison struggles at work in a new episode of "Dexter: Resurrection" available to stream now.

Dexter: Resurrection is doing something we didn’t quite expect. The show has leaned hard into its post-New Blood vibe. It's getting darker, moodier, more psychological.

Dexter: Resurrection episode 4 is a major trip down memory lane for both Dexter and fans as major items from the original show return.
