Dexter Season 8 continues with Dr Evelyn Vogel laying her cards as the Psychopath Whisperer. Debra Morgan kills another person, but Hannah McKay is still MIA. Now, what is up with Masuka's perky overdrive?

Dr Evelyn Vogel is set to make Dexter Season 8 even more interesting. This 'new mum' character tells Dexter he's perfect. She later asks him why he didn't kill Debra when she learned the truth about his Dark Passenger. There is more to discover about this psychopath whisperer.

Hannay McKay is still missing in action, but viewers already saw her in a post-episode teaser a week ago. The show runners are probably taking their time, setting the stage for Hannah's return. Meanwhile, Debra Morgan kills again! She shoots a guy a couple of times without realizing what she's done and how she pulled it off. Could she also be having a swollen brain, much like Will Graham in Hannibal?

The "Brain Surgeon" breaks into Dr Vogel's house to send a message. Dexter and Dr Vogel speculate he may be someone who knows Dr Vogel from her books. Viewers know of at least one character who has read Dr Vogel's works: Masuka.

Masuka laughs an awkward, over-eager laugh when Quinn calls the criminal a "brain surgeon." If there were no spoilers on Masuka's future into the show, Dexter fans would not pay much attention to how he smiles and what he does. But spoilers said Masuka's past will be revealed in this series farewell. Could he be another Dexter, too?

Things get interesting when Masuka walks in on Dr Vogel and Dexter as the two are "brainstorming" on a suspect. "Oh, two good minds at work here," Masuka says, chipper, thrilled, and seemingly overly excited. Did he mean to say "two good brains?"

As for the other characters, Jamie Batista is getting more jealous of the attention Quinn is giving Debra Morgan. Quinn invites Debra for questioning about the man he doesn't know she killed. It seems Dexter's sister is going to be more damaged in the next episodes. Everything is driving her crazy. What about Jamie's publicized bigger role this season -- will she confront Deb over Quinn? And how will Deb pick up her war with Hannah McKay when she returns?
