Richard's changed his tune when it comes to advising Arizona about her custody troubles.
Even Callie knows this case is going to turn nasty, and make Sloan-Grey an uncomfortable work environment for a while. At least she plans on leaving it all behind for New York.

Will Callie and Arizona be able to get through the hearing? Will their friendly co-parenting relationship survive this battle? Will their friendships with the other surgeons?
