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

Based on Ed Sheeran's "Photograph". Season 12.

The human body is simple. When you break a bone, you get it set. When your appendix bursts, you get it removed. And then you modify. You adjust. You learn to avoid the danger, so you don't get hurt again. When it comes to people, on the other hand, it's not as simple. When their hearts break, when their hearts burst, there's no clear method to repair the damage. Post S11. COMPLETE.

An affair rocked Callie's world when her girlfriend Erica cheated on her. Devastated - still with Erica - she finds comfort in a person who promised they would never see each other again. Circumstances caused Arizona to break that promise and they find themselves breaking the one rule they made that night. One night turned into just sex. And just sex... turned into something more.

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

For months she's been gone. Months in which Castle's been forced to believe that Kate Beckett was dead. Eight full months in which he's missed her, craved her, mourned her. Now she's standing on his doorstep, two coffees in slightly shaking hands and Castle's world collapses. Direct spoilers for 4x23 Always, but most probably AU from there.

Castle has a plan for Kate's birthday, but then it eventually morphs into a sub-plan to pull a fast one on Lanie and the guys. Caskett moments in this one. Total AU. *Complete*

Set after the events of 'Control', Callie and Arizona attempt to move forward and create their life together. When an unexpected tragedy befalls Callie, Arizona finds herself with nothing but tough choices.
