Last week, Kristin found out Brody's been playing the field -- now, she says she's ready to do the same. On a puppy playdate with Stacie, Kristin admits she's open to the possibility of meeting someone else, even if she IS still stressing out over Brody. Stacie warns Kristin that friends-with-benefits relationships can be tricky -- and suggests they hit the bars (and scope out some new guys!) that night.Elsewhere, Lo and Brody's friend, McKaela meet up for lunch at Della Terra in L.A. Turns out, they're both members of the same sorority (and, as Lo explains, Kappas are "sisters for life!") When Lo hears McKaela has an interest in cosmetics, she offers to help her get an internship at Smashbox. Before lunch is over, McKaela asks Lo about Brody's relationship with Kristin, and Lo warns her to be careful, telling her to "have fun" with him -- and stay on Kristin's good side.Across town in Venice, Kristin and Stacie begin Operation: Manhunt at a bar called Nikki's. Sick of seeing the same people every night, Kristin tells Stacie she's ready for some new boys. Maybe tonight's the night she'll meet Mr. Right! Or ... not. After brushing off some jerks at the bar, Kristin realizes a good man is hard to find.Around the same time, McKaela meets Brody at Amalfi to thank him for getting her in touch with Lo -- and find out what's really going on between him and his ex. Brody insists there's nothing to be uncomfortable about, but McKaela is wary of starting drama, telling him she's not looking to make any enemies.The next day, Stephanie and Audrina meet at the Anya Hindmarch handbag boutique for a little retail therapy. When Steph asks how things are going with Ryan, Audrina admits to feeling a little bit smothered -- and says she's looking forward to some time apart. First up on her girls' only agenda? Checking out some new bands at the Viper Room. Audrina invites Stephanie to come along, and she immediately says yes.Over at Smashbox studios, Lo shows McKaela around her office -- and sets her up with an interview for an internship. Fortunately, McKaela says all the right things -- and gets invited to assist on a photo shoot the very next day.At the same time, Kristin's finishing up her personal training session -- and complaining about how hard it is to meet a decent guy. She admits to missing Brody, but says she's still upset about the way he ambushed her with McKaela. "It just sucks now," she tells Stacie, mournfully. "Brody and I aren't even friends."That night, Audrina, Lo and Stephanie go to Viper Room to hear a band called Purple Melon -- and run into Justin Bobby! Turns out, he's playing a set with his band, Ed Stanley, and the girls are surprised to learn he's actually a talented drummer. Although Audrina (briefly) considers fleeing the scene, she decides to stick around to say hi to Justin and his bandmates instead. After a friendly hug, Justin tells Audrina he'd love to catch up sometime. Hmm, wonder what Ryan would have to say about that!So where IS Audrina's better half? Moving into his new L.A. abode and getting ready to go on tour. When he reminds her he'll be out of town for the next few days, Audrina tells him she's looking forward to spending time with old friends. She then tells him about her night at Viper Room -- conveniently leaving out any mention of running into her ex.Meanwhile, over at Smashbox Studios, Lo asks McKaela how things are going with her and Brody. When McKaela expresses concerns about Kristin, Lo warns her that Brody's "dated other girls" recently. "Be observant," she tells McKaela. "If something doesn't feel right, it's probably not.That night, Stacie and Kristin (still on their manhunt!) meet Audrina at West Hollywood nightclub, Voyeur. While Audrina fills them in on Ryan's tour schedule, Brody clears the air with Kristin, reminding her that he'll always love her. When Justin Bobby shows up moments later, everyone (except Audrina) seems surprised to see him. While the two of them cozy up together on the couch, Brody tells Kristin things aren't really working out with McKaela -- and leaves the club with Kristin. Looks like the friends-with-benefits are officially back on!
