The celebrations continue as Callie continues to turn to stone and when the others are ready to go, she finally yells at them to stop and to put the baby down and get her out of the carrier. She proceeds to have a full-blown panic attack about taking Sofia away from the protection of the hospital and what might happen to her out in the real world. She's especially nervous about getting into a car, given what happened the last time they rode in one. Bailey stops her as she panics and claws at the straps of Sofia's character, and calmly tells her that the world isn't safe, but that she doesn't feel that way because of the accident but rather just because she's a parent. She promises that it will pass, at least mostly. Her tone and the truth of her words finally calm Callie down. Mere says that some wounds never heal, and you have to just adjust to a new way of living.
Later that night, Meredith and Derek are in bed and Meredith is doing the guilty, wide-awake, stare-at-the-wall-while-your-partner-thinks-you're-happy-and-relaxed thing. Derek wishes that he could tell Richard the good news about Adele getting the medicine, and adds that he hates keeping it from him. And then an anvil CRASHED THROUGH THE CEILING AND KILLED THEM BOTH OMG. Okay, fine, not really, but it might have for Derek's ridiculously too-on-the-nose comment that makes Mere feel that much guiltier. Her VO continues that things might have changed too much and some people never go back to who they were before.
Lexie and Jackson are still at the hospital, and they greet the bus that arrives carrying all of the adorable, tiny African children in need or surgery. Alex holds one of the teeniest ones in his arms and seems as proud as he ever has as he calls out instructions to everyone.
Callie, Sofia and Arizona finally leave the hospital together to join Mark, who is waiting for them at the car with a huge smile on his face. The whole group of them seems to be getting along and happy, and may this hold for a while, please, please, pretty please. Mere wraps up her VO by saying that you might become a whole new person with a whole new life.
