Calzona fans, your 'ship is back on course! At least, that's the sense we get after checking out this sneak peek photo from Grey's Anatomy Season 10, Episode 11 — "Man on the Moon," airing Thursday, December 5.

In the promotional image, Callie (Sara Ramirez) beams brightly as she cradles the head a certain woman with, oh, wavy chin length blonde hair. How many Grey's Anatomy characters have that particular haircut?

Oh yeah, just one: Arizona Tiny-Human-Curing Robbins (Jessica Capshaw).

The road to recovery has been a rocky one for this erstwhile-power couple. Arizona cheats, Callie finds out about it, Callie kicks her out, Callie's dad inspires her to forgive, Callie invites Arizona to the couch, Callie finds out about Arizona's separation fling with Leah (Tessa Ferrer), Callie lets said separation fling be bygones.

And now, something must happen in Thursday night's episode that brings these two back to smiling, face-hugging territory — and we can't wait to find out what it is!

So this is very good news if you were totally prepared to go down with this 'ship. Lifeboat ho!

What has Callie smiling so sweetly? Speculate away in the comment section below.

Grey's Anatomy airs Thursdays at 9 p.m. ET on ABC.
