Kenna Reynolds

Kenna Reynolds is the main villainess from "Love Thy Neighbor," episode 16.02 of NCIS.

She was played by Lise Simms.

Kenna Reynolds is the wife of Dan Reynolds, but as later revealed, Kenna was also a villainess and serial killer, having killed nine victims in a six year span between 2005 and 2011. She gained the nickname, "The Dentist," due to the fact that she would remove a tooth from each of her victims as a trophy, and regarding her method of murder, Kenna had been known to shoot, stab, and strangle her victims to death. After her last kill in September 2011, Kenna settled down and married Dan, and they had children together at that same time.

One of Kenna's nine victims was revealed to be a woman named Pamela Calweiler, whose cousin was Lt. Derek Mooney, the couple's neighbor. Pamela's murder led Mooney to begin writing a book on The Dentist, and it was after the ninth and final murder that he suspected a man named Lewis Dacey of being the serial killer. However, Mooney called Dacey some time before his death to apologize, as he had broken into the Reynolds household and found a box of the victims' teeth, meaning that he was closing in on Kenna's true identity. Knowing that Mooney had taken her box and realizing that he could expose her secret, the evil Kenna stabbed Mooney to death in his hot tub, using a box cutter to commit the murder before taking back her possession.

After the box of victims' teeth were found in the Reynolds' home, Dan was suspected and subjected to Leroy Jethro Gibbs' intense interrogation. However, Kenna ended up revealed as the villainess when her purple nail polish was found on the box, and that led to Gibbs and Jackie Sloane encountering Kenna at her garage. The villainess snarled at the pair over her husband behind held at NCIS, but after the pair outed her as The Dentist and as Mooney's killer, Kenna confessed. In addition, the evil Kenna stated that Mooney was going to ruin the good life she had, while also claiming that she was past her actions as a serial killer. Gibbs handcuffed and arrested Kenna following her reveal and confession. A motive was never revealed for Kenna's actions as The Dentist, and NCIS was left wondering how Dan never knew about Kenna's heel persona.
