ABC's "Grey's Anatomy" - Season TenIf you're ready to board the "Larizona" 'ship now that Tessa Ferrer is returning as Leah, Arizona's former love interest, you may be disappointed.

"Grey's Anatomy" star Jessica Capshaw revealed more information about her character's Season 13 romantic future, and it doesn't sound like Arizona is necessarily on the brink of a great love. While show creator Shonda Rhimes did promise new romance, it probably won't arrive overnight and may not involve Leah.

"A love interest certainly doesn't mean necessarily a huge relationship," Capshaw told "It kind of just means exactly that. I think there's an opportunity for there to be some really fun, flirty, exciting, sexy stuff that comes up for [Arizona]."

Her relationship with Leah will be interesting, whether or not it takes a romantic turn again. The two previously ended on awkward terms because Leah -- unsurprisingly -- didn't take too kindly to Arizona dumping her for Callie (Sara Ramirez). Capshaw says Leah's return will be "dramatic," but also described it as "very cool."

Other than Leah, it's not clear what other love interests could crop up, or even what exactly Arizona wants.

"I'm not really sure if it's just going to be that Arizona is the kind of person who has a bunch of little relationships, or if she's interested in being in a big relationship again," Capshaw said.

We'll find out more as the season progresses and when Leah returns in Season 13, Episode 6.

"Grey's Anatomy" airs Thursdays at 8 p.m. ET on ABC.
