While Whitney and Frankie were largely left out of any drama and Wahler has yet to appear, keep reading to see where the new cast members fit into the bigger picture and who they and the returning stars already have beef with.
Barton is most known for her work on "The O.C.," which she said brought her to a level of fame she "wasn't prepared" for at the time. During her intro on "The Hills" last night, she glossed over some of her spotted past in L.A., simply saying she's "had a couple of really bad things happen to me here." While she went into detail about being the victim of revenge porn, she didn't talk about her DUI or mental breakdown.
After calling the revenge porn case "pretty traumatizing," she also opened up about another person who we'll see her confront later this season: Perez Hilton. Of the blogger, she said, "He just loved coming after me. Perez was a total bully back in the day, he was awful to me and lots of women."
The episode ended with everyone going to a party for Stephanie Pratt, with Spencer inviting Perez. Expect a showdown between the two next week.
"I'm excited to be reconnecting with this group of friends I used to run around with," she said, explaining her loose connection to the other stars, "but now that I'm back I'm definitely cautious."
Brody Jenner is one of the many who returned to the show with a better half, though he may not call wife Kaitlynn that. In the premiere, he talked to Spencer and Frankie about the couple's constant "bickering" and their opposing stances on having children right away.
"She wants kids. I want kids, but I'm not in a hurry to have kids," he told his friends. "There's absolutely nothing wrong with my life ... I wanna have kids, just not right this second.'"
Viewers witnessed one of his fights with Kaitlynn during the premiere, after he returned from a DJing gig much later than she was expecting him. After he called Kaitlynn both a "psychopath" and a "nightmare," she explained the anxiety she feels waiting up for him to come home. He didn't seem to care.
He also reiterated his stance on kids in a confessional. "While I don't have kids, I'm gonna pretty much do what I wanna do and live for myself, as opposed to live for another human being," he explained. "I think that's why she wants kids, she wants me to change in that way."
Brody also has a little drama with Spencer, who was "shook" he didn't get an invite to the couple's wedding. "I don't hold grudges," Pratt said in a confessional, "JK, I definitely do. So this is going to be fun."
Explaining the snub, Brody said, "Spencer went off the grid for a while. I had a lot of friends in my life where we spoke every day and Spencer wasn't one of those people." Frankie was also "butt hurt" about not getting an invite either.
It wouldn't be "The Hills" without some drama involving these two and it seems like their storyline will definitely deliver. The biggest issue for Spencer is sister Stephanie Pratt's return, as the siblings have been on the outs for years.
"We haven't had a relationship for a long time," explained Stephanie, who only found out her brother was having a baby from reading about it online. She returned to L.A. hoping to "reconnect with my brother and get to know my little nephew." He called her constant bad-mouthing him in the press, however, "frustrating." We'll see how this one pans out.
Heidi's also been dealing with "severe anxiety" after the two welcomed son Gunner, who she's just not ready to leave at home with someone else yet.
The episode actually began with Audrina moving into a brand new house, after a nasty divorce form Corey Bohan and some time living with her parents. "I've had a baby, I got married and then I got divorced. So, it's been a crazy couple years," she explained at the top of the show, "I feel like I'm waking up from a bad dream."
She, too, was dealing with anxiety, after a custody battle with Bohan over their daughter Kirra.
"I cut off a lot of friendships and I cut off a lot of opportunities all for this guy that treated me like shit," she later explained to Stephanie. "I was so numb and isolated and so depressed I lost over 20 pounds."
She later broke down in tears as she said she "never thought" she would be a single mother at 33.
Viewers also saw a long-awaited reunion between Patridge and ex-boyfriend Justin Bobby, who, yes, still looks really good. Their dinner was filled with the awkward pauses and overlong stares "The Hills" has always been known for -- and may or may not have ended with them hooking up again. Neither would say what happened when the cameras stopped rolling.
Last, but not least, was Brandon Thomas Lee's introduction. At 23, he's much younger than the rest of the cast, though said he's friends with Brody Jenner.
He had just moved into his first home, with mom Pamela Anderson swinging by for her very first visit. After doing motherly things like checking his cabinets for nutritious food and saging the house, the two also talked about Brandon's strained relationship with his father.
"We're not really on speaking terms yet," said Brandon, who got into a physical altercation with Tommy Lee last year. "You're both 16 years old," Anderson exclaimed.
In a confessional, Brandon added, "Me and my dad have had our ups and downs for sure. This guy got famous at 18 years old and most people know when you get famous at a certain age, and very famous, you end up staying that age."
"I'm a lot like him, but it doesn't mean I have to be like him," he also said.
Summing up the dynamic perfectly, Pam added, "Our family is a little dramatic and crazy."
