Meredith was working in the pit when a trauma came in. A car accident victim, appeared to have internal bleeding and and a broken clavicle. Meredith had them page ortho. The patient went to X-ray and had a CT scan, Meredith was scrubbing in when Callie walked into the scrub room. Callie mumbled "Just Great" when she saw she was going to be in surgery for hours with Meredith.

"Dr Torres." Meredith greeted the other woman. They spent the next three hours in surgery together in silence. When they finished and were scrubbing out. Meredith looked at her old friend and said "We need to talk." Callie looked at Meredith and said "Yes we do." They walked out and found an empty on call room.

Meredith said "Do you want to start or do you want me to?" Callie said "Oh no, I'll begin. What are you doing? I thought you were my friend. The second I leave you jump my wife's bones? And since when are you interested in women?"

"First of all, Arizona is your EX-wife. And you are right, you left. Plus you have a girlfriend." Meredith was saying when Callie interrupted "Had. Had a girlfriend. We broke up."

Meredith shook her head "Unbelievable. Did you think that because you and Blake are no longer together, that you can just come back here and be with Arizona? After all you put her through? She is not some object that you can pull out when it's convenient for you."

Callie replied "Its not like that. Arizona and I have a complicated relationship. You don't understand."

"I understand that you hurt her. I won't let you hurt her more. It has to stop.I love her, it wasn't planned. It just happened. I won't apologize for that. We need to work all this out like adults because there are children involved. But Callie do you honestly think it's fair for you to expect Arizona to drop everything because you have all of a sudden decided that you want to be with her?" Meredith started pacing, she was furious "She made her decision, she's with me. We are a family. The sooner you come to terms with that, the better off we all will be." With that, Meredith walked out and left Callie looking bewildered.

She found her girlfriend in the attendings lounge. Arizona was changing out of scrubs. Meredith came up behind her and put her arms around the blonde and placed a kiss on her shoulder. "Hey you." Arizona said as she turned around to give her girlfriend a proper kiss. Meredith placed her hands on her girlfriend's bare back and Arizona said "I need to finish getting dressed before this gets out of hand." She pulled her shirt over her head. "Are you finished? I am so ready to go home. I talked to Bailey today and I have so much to tell you."

Meredith replied that she had some paperwork to finish and would be about another hour. She told Arizona to go ahead and feed the kids she would be home shortly.

Arizona kissed her girlfriend goodbye and headed down to daycare to pick up the he kids.

Arizona was getting ready to walk out of daycare with the kids when she ran into Callie. "Oh hey, I was going to call you. We need to figure out a visitation schedule"

Callie grabbed the diaper bag off of Arizona's shoulder and walked with her to the car. After they had the kids all buckled in, Sofia kissed her Mommy goodbye. Arizona and Callie stood outside the car to talk, Callie asked "Would it be okay for me to pick her up on Saturday? I'm working with a realtor and she has a few places lined up. As soon as I find a place and get settled we can discuss a schedule."

Arizona replied "Thats fine. You can see her anytime. I would never keep you from seeing her." She turned to open the drivers door and Callie grabbed her wrists to stop her. Arizona looked up into the eyes of her ex wife. "Callie?"

Brown eyes stared into blue ones "Thank you Arizona." She turned and went back into the hospital.

Arizona called for pizza before she left the parking lot so it would be delivered when they got home. She pulled up and got everyone in and settled. She was holding Ellis and helping the girls with their homework while Bailey was coloring. He didn't like feeling left out so this was his homework. The doorbell rang and Arizona went and retrieved the pizza. They were eating and laughing and being silly when Meredith walked in. Zola and Bailey both greeted her with "Hi Mommy." Ellis looked up and said "Me" Everyone became really excited and Sofia looked at Arizona and said "Momma, did you hear that?" Ellis looked at Arizona and said "Ma" Meredith laughed at that and said "Looks like you're Momma and I'm Mommy."

Arizona looked a little worried "Are you okay with that?" Meredith studied her girlfriend and said "Are you kidding? That child already thinks she came out of your vagina."

She wrapped her arms around her girlfriend and said "let's get these kids to bed so we can go to bed."

Ellis was down and they tucked in the girls and were saying goodnight to Bailey when he asked "Zona? Sofia has two Moms, are you my mom too?" Arizona's eyes were as big as saucers. She looked and shrugged at Meredith who told Bailey "Is that something you want?" He nodded and Meredith said "Okay then, we can talk about that. But now, you need to go to sleep okay?"

Arizona and Meredith sat in bed discussing the kids and the whole 2 Moms situation. Arizona said she didn't want to replace Derek and Meredith told her "Arizona, you have been a Mother to my kids for months. Unless this is something that you don't want?"

Arizona replied "Oh no no no, I do, I just didn't want to overstep. I would love to be your kids second mom." She kissed her girlfriend and then proceeded to tell her the good news she learned from the chief. Meredith kissed her and said "Let's celebrate."
