Callie (Sara Ramirez) and Arizona (Jessica Capshaw) aren't exactly a happy couple right now. In fact the Grey’s Anatomy docs can barely be called a couple at all at the moment, though they are still married. However, Grey's Anatomy Season 10, Episode 9, "Sorry Seems to be the Hardest Word" is going to take us back to a happier time for the pair — well, maybe. Kinda.

We know the episode will feature flashbacks, and according to the official synopsis, "through [these] flashbacks, we learn some surprising details about Callie and Arizona's marriage."

Surprising details, you say? While the whole point of a surprise is that you can't guess what it is, we're going to take a stab at speculating what this episode will hold, anyway. We'll see if we're anywhere near the mark tonight!

More details on the way Callie treated Arizona post-surgery. For a while Arizona seemed very, very insecure about herself as a physical/sexual being because of her leg. However, from what we saw last season, Callie rarely gave Arizona a reason to think she didn't still find her very, very sexy. While it's totally possible that Arizona's insecurities are all (understandably) in her head, is it possible that Callie actually did do or say something that made Arizona think she didn't want her anymore? It wouldn't even have to be a pointed or cruel comment — maybe it could even be something Arizona misinterpreted?

Arizona overheard Callie ranting. While Callie tried to be as supportive as possible to her wife, there were times when she cracked, such as when she ranted to Bailey about how hard marriage can be. Maybe it will turn out that Arizona overheard that little speech, or something else like it, and it caused hurt feelings.

General communication failures. It's also possible that it will be something more subtle, such as a series of scenes that just show exactly how far apart Callie and Arizona had grown over the course of the year.

This wasn't the first time one of them cheated. While another cheating incident would be more than a "surprising detail" in our mind, it's possible that the show is going to delve into a big twist like this. After all, it is Grey's Anatomy!

What do you think the surprising details will be? Let us know in the comments below.
