We're still two and a half weeks away from the 2014 return of Grey's Anatomy, but now we have new details about the return episode — Season 10, Episode 13, "Take It Back," airing February 27 — and they involve Callie (Sara Ramirez) and Arizona (Jessica Capshaw).

In ABC's synopsis of the episode, the Calzona news comes midway through: "Arizona and Callie decide whether or not to move forward together."

Let's hope this doesn't cause another breakup — we want to explore uncharted territory in Callie and Arizona's relationship.

A recap of the chronology so far: They said their "I love you's" long hence, moved in with one another, broke up, moved out, made up, married, got pregnant, faced down death via a car crash, welcomed daughter Sofia, got engaged, married, faced down death (and an amputated limb) via a plane crash, had a miscarriage, suffered infidelity, separated, and got back together again.

So after such an exhaustive and tangled romantic history — and given their recovering relationship — we suspect that "moving forward together" means something else… like perhaps changing up their real estate! (We already know that new, potentially-permanent sets on the Grey's studio lot mean a change for a longtime couple.)

But what do you think? Speculate away in the comments below!
