Dexter Season 8 just got a little bit of NBC's Hannibal on its latest episode, S8X3: "What's Eating Dexter Morgan?" The Brain Surgeon case has led Dexter to one of Dr Vogel's former psychopath patients. But is the Hannibal guy the Brain Surgeon himself? And when will viewers see Hannah McKay again?

Spoiler Alert: This feature contains spoilers for those who have not seen Dexter Season 8, Episode 3: "What's Eating Dexter Morgan?"

Meanwhile, Debra continues to spiral out of control due to bouts of PTSD. Dr Vogel asks Dexter why he hasn't killed Debra after she's found his dark secret. But Dexter establishes he loves Debra. Dr Vogel tells him he just values Debra for what she's done for him, i.e. loved him unconditionally. It seems it is only a matter of time before Dexter's patience for Dr Vogel run out.

Dexter Season 8: When will Hannah McKay return?

Hannah McKay will return to Dexter Season 8 on or before Episode 6: "A Little Reflection." Yvonne Strahovski will soon reprise her role as the fugitive poison connoisseur. The TV.com episode guide for this episode reads:

"Dexter monitors a young sociopath. Dexter and Deb get back to normal, but are surprised from a visit from Hannah."

Interestingly, the quick guide reveals Debra will soon get over killing LaGuerta. This should figure in speculators' predictions as to how Dexter will wind up toward the end of the series. The series finale of Dexter will air on Sept. 15 via Showtime.

The Brain Surgeon Case Closed at Miami Police

The Miami Police has declared the Brain Surgeon case is closed, following a suspected killer's suicide. However, Dexter and Dr Vogel know better. They do know the killer is on to them. He even sent them a neatly boxed little package containing someone's Occipital lobe (connected to the eyes). The Brain Surgeon is probably someone Dexter and Dr Vogel both know, someone who has read her book on psychopaths. At this point, however, the only person who has admitted to having read Dr Vogel's book is Masuka. Could it be him?

Later on in the series, Dexter will take on a protégé and teach him about Harry's Code.
