Mayhew, Dixon (panther): Dixon takes after the other side of the Hotshot panthers, with lighter hair and a stocky build.

The siblings are hired by Victor Madden to watch over him during the day at his mansion situated between Musgrave and Toniton. (DAAD; mentioned DR)

Merlotte, Bernadette “Bernie” (pure shifter): The mother of Mindy, Craig, and Sam, Bernie remarries about two years after the death of Sam’s father and keeps her shifter status a secret, making excuses to explain her absence on full-moon nights. As they watch the Great Reveal on television, Bernie finally tells her husband, Don, her secret and shifts in front of him, but Don does not react as she hopes: He shoots her. He is charged and taken into custody, and they divorce while he remains incarcerated awaiting his trial, unable to make bail.
Bernie is working as a receptionist/secretary at an elementary school when she is shot. They hire a replacement for her while she heals, but she’s not at all certain she’ll still have a job when the new school year starts. Longtime friends become strangers, but she remains determined to see her son Craig safely married even as her town struggles with the presence of shifters in their midst. (STW; mentioned FDTW, DAG, DITF)
Merlotte, Craig: Craig, Sam’s brother, has plans to get married when the shifters reveal themselves, but his engagement is put on hold while his fiancée’s family adjusts to the fact that his brother and mother are shifters. Like his older brother, Craig proudly served his time in the military and now does tech support for a large accounting firm in Houston after graduating from UT Dallas. (STW; mentioned FDTW, DAG, DITF)
Merlotte, Deidra Lisle: Pretty Deidra is married to Craig, Sam’s brother. Although her parents are uncertain about the shifters in their new son-in-law’s family, Deidra is not worried about the effects on her future children. She’s currently training to become an EMT but may have to put her career on hold for a bit as she and Craig start their new life together by preparing for the baby that’s already on the way. (STW; mentioned FDTW, DAG, DITF)
Merlotte, Sam (pure shifter): Sam Merlotte did his duty for his country, serving in the army for four years before buying his bar with money left after the death of his father, a former military man and pure shifter himself, and settling in Bon Temps. A rare pure shifter, Sam can become anything he wants but prefers the form of a collie, and it is in this form that Sookie takes him home from the bar, thinking he is really a dog. Sam fully intends to wake first and leave, but he oversleeps and surprises Sookie in her bed. Sam tells her about himself and also informs her that vampires are really dead.
When Callisto arrives, he spends time with the maenad, offering his companionship as tribute, and they enjoy their romps in the woods around Bon Temps together.
Sam watches over Sookie as she goes deeper and deeper into the supernatural world. He’s especially worried about her involvement with vampires. Although he normally remains neutral in supernatural goings-on, he accompanies Sookie to the parley between Alcide and Furnan and changes into a lion to protect her when they are attacked by Priscilla Hebert and her Weres. He is then drawn into vampire affairs when he is captured by Sigebert, who, seeking revenge on Eric and Felipe, finds them in Merlotte’s parking lot. Freed by Sookie, Sam is saddened by the fact that he was attacked walking the short distance from his bar to his trailer and worries what more will come.
When the shifters announce the Great Reveal on TV, Sam and Tray Dawson shift at the same time in Merlotte’s. Across the world shifters are revealing themselves, including Sam’s mother, who is shot by her second husband when she shifts in front of him. Sam rushes to her side, leaving Sookie to manage the bar in his absence. While he is gone, Crystal is found crucified in the parking lot. Like many people, Sam wonders whether she was killed because she was a shifter or because of her actions. He returns as quickly as possible to take over from Sookie and finds out that she has unwittingly married Eric. He reacts badly. His overall concern for her grows as her new involvement with the fae leads to her kidnapping and torture.
The wedding of Sam’s brother, Craig, has been postponed as Craig’s fiancée’s family struggles with the shifter aspect of their future son-in-law’s family, and Sam continues to hope for a new date to be set. Having asked Sookie if she would accompany him months before, he confirms that she will attend with him even after he begins dating Jannalynn Hopper. Sam fears that Were Jannalynn is too intense for his family. When the wedding finally takes place, the families are faced with protests but wind up surrounded by shifters who have come from all around to offer support and protection. Jannalynn shows up unannounced, hurt and angry that Sam didn’t think she was appropriate to bring to a family function, and the two agree to discuss their relationship when they both get home. They do and decide to continue dating.
Sam is already worried about the future of his bar when a firebomb is thrown through the front window. Damages and injuries are minimal, and he is quickly able to reopen, but business continues to slide as customers are drawn to Vic’s Redneck Roadhouse, a new bar that Victor Madden has opened nearby. Sam’s problems increase when four thugs high on vampire blood enter Merlotte’s, intent on causing trouble and taking Sookie. Sam, Jannalynn, an off-duty Andy Bellefleur, and the suspiciously well-placed and well-timed private detectives Jack and Lily Leeds subdue the men. The motive behind both attacks is eventually revealed when a wild-eyed Sandra Pelt shows up at Merlotte’s, publicly admitting that she has been attempting to kill Sookie. With Sam’s help, Terry Bellefleur manages to disable Sandra, and she is taken first to the hospital and then to jail, but she manages to escape. Struggling with the bar’s mounting costs and lack of business, Sam reluctantly accepts a sizable loan from Sookie to tide the bar over. He and Jannalynn are spending the afternoon together at his trailer when they are accosted by Sandra and held at gunpoint. She forces Sam to call Sookie to lure her to his trailer, but sensing something is wrong, Sookie has Sam drive out to her house instead. When the trio arrives, Jannalynn takes advantage of a distraction and viciously attacks Sandra while Sam and Sookie stay on the fringes, trying to help. Sam’s nose is broken when he grabs Sandra’s hair and she punches him, but Jannalynn ultimately gets the upper hand and breaks Sandra’s neck, then crushes her skull to finish the job. Worried about the ramifications of reporting the death, Sam and Sookie decide to dispose of the body instead and, followed by a wounded Jannalynn, carry Sandra into the woods to the fairy portal and shove her through. After returning to the house, Jannalynn sets Sam’s broken nose before the pair leave for his trailer, disposing of Sandra’s rifle along the way.
