Callie and Arizona’s breakup resulted in Callie doing everything possible to forget about being left at the airport. She eventually rekindles her situationship with Mark and tries to move on. However, several weeks later, Arizona returns from Africa and tells Callie how much she misses her at her doorstep. Callie gives Arizona the cold shoulder, letting her ex know she broke her heart.

Arizona begs and pleads to get back into Callie’s good graces. Eventually, Callie decides to let her guard down and tell her she’s pregnant with Mark’s baby. She asks Arizona if she’s still ready to make things work. Arizona agrees to co-parent with her and Mark, though she’s not OK with them raising a baby with the hunky plastic surgeon.

However, when Callie nearly dies in a car crash on their way to a BNB, Arizona, Mark puts their differences aside in between musical numbers (did you know Calliope means music?) and cares for Callie and their newborn daughter, Sofia Robbins-Sloan.
