Big kahuna

The McKays are back! The family that feuded with the Ewings during the original “Dallas’s” later years is slowly creeping back into TNT’s sequel series: Hunter, a McKay grandson, was introduced earlier this year, while this week’s episode, “Victims of Love,” will bring back Tracey, who’s now played by Melinda Clarke. Need a refresher on the McKays and where they fit into the Ewing-verse? Read on.

Devil next door

Carter, the meanest McKay. When Dreadful Jenna Wade™ forced our beloved Ray Krebbs to move with her to “Europe,” he sold his Southfork-adjacent ranch to Carter McKay (George Kennedy), who turned out to be the crummiest neighbor a Ewing could ask for. Carter constantly threw loud parties and borrowed Miss Ellie’s tools without returning them. Kidding! The real reason Carter sucked was because he started a range war with the Ewings in a convoluted scheme to seize control of Section 40, the oil-drenched Southfork parcel that everyone on “Dallas” tries to seize at one point or another. Although the Ewings won the war and kept their land, Carter had the last laugh: In “Dallas’s” final episodes, he sold his ranch and saddled the Ewings with an even worse next-door neighbor — Michelle Stevens.

Big fish, little fish

… And also the sharpest. When Carter wasn’t bringing down the Braddock County property values, he was shaking up the oil biz. Carter was revealed as the brains behind Westar, Ewing Oil’s biggest rival, and the puppeteer who had been pulling Jeremy Wendell’s strings for years. (All together, “Dallas” diehards: Yeah, right!) Actually, Carter really did display solid business acumen. For example, when J.R. and Bobby (Larry Hagman, Patrick Duffy) backed out of a deal to supply the Soviets with Texas crude — citing patriotism! — Carter stole the deal and schooled the brothers on how the world really worked, delivering a prophetic, Chayefskian speech (“Whatever America used to be, it isn’t anymore. …”). Carter’s biggest coup: Tricking J.R. into giving up control of Ewing Oil in “Dallas’s” penultimate episode!

Do the hustle

Tracey, the sexiest McKay. Bobby and Cliff were chillin’ at a pool hall one night in ’88 — because that’s how the Barneses and the Ewings rolled that year — when jean-skirted Tracey Lawton caught the eye of the recently divorced Bob. Back then, Tracey was played by Beth Toussaint, who looked a lot like “Terminator” heroine Linda Hamilton, but with poutier lips and punier biceps. Tracey turned out to be a pool shark, but that wasn’t her only secret: She was also a recent divorcee (hence the “Lawton”) and Carter’s estranged daughter. Once again, Bobby found himself playing Romeo, but his romance with this Juliet dimmed pretty quickly and Tracey soon departed Dallas. She didn’t leave in bandages like Bobby’s first Juliet, although somewhere along the way, Tracey — like Pam — did pick up a new face.

Tommyknocker

Tommy, the nuttiest McKay. Oh, this guy was a total whack job. Tommy, Carter’s drug-dealing son, arrived at the McKay ranch after serving a jail sentence in “South America,” and when Tommy wasn’t making a quick buck by spying for J.R. or screaming in the rain, he was hitting on every woman on the show. In April’s case, Tommy hit on her literally, which prompted Bobby to beat the j. eddie peck out of him. Tommy tried to get revenge by blowing up Bobby, and when that failed, the gun-wielding loon was accidentally shot and killed during a struggle with dear old dad. Tracey told Bobby she didn’t blame him for Tommy’s death, but warned him about Carter: “Stay out of his way, Bobby. I don’t want to come to your funeral.” (Silly Tracey. The show already did that storyline!)

Desk job

Rose, the awesomest McKay. Although Carter was sweet on Sue Ellen, he married Rose Daniels (Jeri Gaile), an Iowa farm-girl-turned-beautician with a penchant for bold print dresses and shoulder-brushing earrings. Rose loved “Mac” and did almost anything he asked, including sleeping with Cliff Barnes so Carter could videotape the encounter and use it to derail Cliff’s resurgent political career. Poor judgment aside, Rose was a hoot because she spent most of her time sashaying around the house in heels and lingerie with a drink in her hand, and Gaile brought a lot of heart to the role, making Rose one of the brighter lights during “Dallas’s” later years. Best of all, when Rose finally got fed up with Carter, she knew how to teach him a lesson: by having sex with J.R. on her husband’s desk! Good going, darlin’.

Aiding the enemy

Ellington, the adopted McKay. When Carter wasn’t siring nutjobs like Tommy, he was putting them on his payroll. First there was snarlin’ Fred Hughes, Carter’s right-hand man during the range war, whose solution to every problem was to shoot a Ewing. Miss Ellie once referred to Hughes as Carter’s “pet dog,” which tells you everything you need to know about what a jerk he was. Then there was Peter Ellington (Philip Anglim), McKay’s sidekick during the “War of the Ewings” reunion movie. Ellington was super enthused about pushing through his boss’s latest deal with the Ewings — to the point of trying to blow up J.R. and taking Sue Ellen (Linda Gray) hostage. Is it me, or was Ellington a little too — what’s the expression I’m looking for here? — into Carter McKay? Did Rose know about this?

Splitting heirs

Hunter, the mystery McKay. John Ross (Josh Henderson) mentioned playing basketball with “the McKay brothers” during TNT’s first season of “Dallas,” but we didn’t meet one of them until this year, when Hunter showed up and told John Ross how he made a killing by taking his video game company public. Later, we learned Hunter has revenge on his mind and is secretly helping Nicolas and the drug cartel take over Ewing Global. If Hunter is Carter’s grandson, does that make him Tommy’s son? If so, does he hold a grudge against the Ewings because he blames them for his father’s death? Most importantly: Now that Hunter’s here and Tracey’s back, will more McKays show up? No matter how it all turns out, just remember: Whatever trouble the McKays cause next, their arrival in Dallas can be traced back to one person — that awful Jenna Wade. Everything is always her fault, isn’t it?
