Dean Redding

Dean Redding is a part of the Naturals Program. He's a profiler and Cassie Hobbes' boyfriend. His dad, Daniel Redding, was an infamous murderer. He's afraid that he is similar to his father and that he will hurt someone.

Dean, when profiling an UNSUB, says "I" instead of "you."

Books
Killer Instinct After an Unsub murders a college student and places her on the university president's lawn- without being seen the Naturals investigate. After investigating a video of the body from the news channel, Dean immediately realizes that the girl, Emerson, was murdered in the exact same way his father killed his victims- bind them, brand them, cut them, hang them. He tells the rest of the Naturals, then calls Briggs to tell him his father has a copycat. ⚠️SPOILER⚠️ Eventually, they figure out Dean's father actually has an assistant- and not just one, but three of them.

Twelve In Twelve Dean is studying with Sloane and Michael, at the FBI Academy. They're training to become a team with Lia and Cassie, who are civilian consultants. As a requirement to join the academy, he started to see a psychologist because of his father and to make sure that he's psychologically intact.

Relationships
Cassie Hobbes

At first, it seemed like he didn't like Cassie. Since Cassie and Dean are both profilers they had to study together and he was always uncomfortable. During a game of truth or dare they share a kiss. In Killer Instinct Dean is more familiar with having her around and trusts her. At the end of the book, they reunite and share a kiss. After that, they are pretty much inseparable and are in love. In All In they share kisses and are often teased by Lia.

In Twelve It's hard for them to be apart but they make it work. At the end of Twelve, he encourages her to get the help that she needs through therapy.

Lia

They have a brother-sister relationship. They are very close but fight/fought often, because Dean is very protective of her even though she believes she can take care of herself. She is (a lot of the time) jealous or too overprotective of Dean's relationship with Cassie. At first, Lia has a hard time accepting that he is relying more on Cassie instead of her.

Michael

For reasons oftentimes unclear, Dean and Michael have a rocky friendship. Part of this is due to that when Cassie first joined the program, they were both incredibly jealous over her. Cassie was also unsure which guy she loved. As Dean and Cassie's relationship grew deeper, Michael had a hard time accepting it because of his feelings for her. Through time and blood, their friendship grew strong.

"Michael: 'Do. You. Like. Me.'" "Dean: 'You've had your moments.'""Michael: 'What?'""Dean: 'I don't have to like you. We're family.'"Daniel Redding

Dean lived in a house with his father unaware that just a few meters away was a shed where his father murdered women. Daniel's Method was Brand them, bind them, cut them, hang them. As a young boy Dean helped the FBI to take his father down by helping Agent Sterling escape. In Killer Instinct, Daniel had three assistants kill people in the same way he had before he was caught. This was a way to get to Dean. Dean is afraid of becoming like his father, especially because he can see so well into UNSUBs (Unknown subjects, or the killer) minds. Dean understands a killers mind so well, especially after living with one.

Judd

Judd was hired by Agent Briggs to be Dean's caregiver after the FBI arrested his father Daniel.
