Callie and Arizona get married May 5 on Calzona's Grey's Anatomy. This we know.

Here are details you may not know, but now do, via Sara Ramirez and TV Line:

Not only does Bailey officiate Calizona’s nuptials, but she serves as the couple’s spiritual guide after Callie's mom fails to approve of the same-sex union.

“Bailey says to her, ‘God is everywhere. God is in you and me,'" Ramirez says. 

"'Between us here in this room. And you don’t have to be in a church in order to marry someone and have a meaningful ceremony, union, marriage, wedding.’”

“So at the end of the day, Callie starts to embrace and understand that the person she needs to look to for self-assurance, love and acceptance, is inside of her.”

As for the other big event that day, pertaining to Meredith and Derek?

The episode synopsis we revealed earlier this week includes this telltale line: “Meredith and Derek make a decision that will change their lives forever.”
