There had been so many mistakes made by both Callie and Arizona, and no one was more aware of their errors than themselves. From to the dissolution of their marriage to the present, so many things had gone wrong. But there was no way to change the past. Luckily for them, it seemed that they were always drawn back to one another, no matter what, time after time. Post 12x24

Rachel Berry didn't particularly consider herself a storyteller, but who was she to turn down a request? Luckily, she had some inspiration to draw from, including - as all stories in her humble opinion should - both a musical and romance. And, like every great tale, it all began with once upon a time...

Callie Torres and Arizona Robbins didn't exactly have the best friendship. In fact, despite being neighbors, there wasn't really a friendship between the two of them at all. But it was kind of difficult to dislike someone you were stuck driving across the country with. Two girls. Two weeks. Eleven states. One road trip. A lot can happen when you're along for the ride.

For Callie, it was being forced to spend the last three dollars in her pocket on a random book in a used bookshop. A book with notes written all over the margins by A. Robbins.

Of all of the gin joints, in all of the towns, in all of the world... Callie Torres walked into Arizona's. And it just might be the best thing that ever happened to either one of them. AU

Not in med school anymore, Callie and Arizona are still learning that life and love both come with some twisting, turning surprises. Just as some plans go awry, certain expectations weren't meant to be, and that just might work out for the best. AU

When bones fracture, they have to go through three stages before they really heal. They need to react, repair, and remodel, and it takes time. Not taking the time for these steps means that the fracture will never really go away. Arizona didn't take the time to properly heal; she skipped steps. In order to fix her life, she had to re-break it and heal correctly. Post 9x24

They didn't plan to meet each other. Arizona didn't plan on Callie being more than one night; Callie didn't plan on Arizona being so resistant. But maybe the best outcomes arrive from the unplanned. AU
