In the AU, Cristin was there and Owen and Callie happened. The only difference there was that Ellis Grey never got Alzheimer's and Richard left Adele when Meredith was a toddler. Callie's coming out had nothing to do with Cristina. If anything, Mark was the biggest catalyst there. Addison put the idea in Callie's head when she came back to visit and Mark encouraged her to go for it.
