It’s been a long, exhausting, and dramatic season for Grey’s Anatomy golden couple Callie and Arizona, but on tonight’s episode, Season 9, Episode 18: “Idle Hands,” things are going to take a turn for the better — and the sexy.

As seen in the sneak peek clip, Arizona propositions Callie about having “sexy time,” and though we unfortunately don’t get to see them talk much about it before Bailey interrupts, portrayers Sara Ramirez and Jessica Capshaw promise that it will be unforgettable.

"It's very tender and it's very collaborative," Jessica told TV Guide. "Shonda has always been really lovely and really caring about creating an elegant, honest, and earned relationship between these two. It's never been gratuitous. Their intimacy has always been really playful and fun and passionate and exciting. Their rekindling is in that same vein. I have to wear lingerie, so I'm a little nervous about that."

But according to Sara, Jessica has nothing to worry about — she teases that Arizona is seriously sexy in this episode.

"Watch out, because Arizona is about to give us all some serious hotness," she teased with a laugh. "Some serious hotness from Jessica Capshaw. I think the fans will appreciate it."

And this sexy side of Arizona comes out because of a big change in her life: a new pair of feet!

“Arizona's had a prosthetic with a flat foot this whole time and she's really insecure about that, but now she has a prosthetic that can wear heels and that, in turn, makes her feel more confident and more sexy,” Sara spilled.

Ultimately, creator Shonda Rhimes wanted them to go through a long journey to get to this place in their relationship in which they’re finally feeling normal and comfortable again.

“We've been having a good time bringing them back together and really getting them past all their milestones because it's important,” she dished, adding that it’s about “finding their way back to feeling like themselves again and finding their way to feeling romantic and sexy again, to feeling like the person they were with their spouse again.”
