Anna returns working with Joelle and the CIA, focused on tracking Darius as he pursues a human trafficking ring. She is all business, initially causing tension with Callen.

The episode ends on a positive note for the couple, with Anna opening Callen's door (wearing one of his shirts), providing a rare moment of domestic happiness for him.

The episode brings back Darius (formerly Comescu), who survived a previous encounter in Cuba, forcing Callen to confront the life he never lived. While Darius was raised by Callen’s father, Nikita Reznikov, Callen feels no fraternal connection to him.
