Summary: Post-Season 6. Arizona and Callie are at a good place finally but a visitor catches them both off guard. I don't own anything.

Callie and Arizona were having a relaxing night finally. They both had worked 48 hour shifts with multiple surgeries and were looking forward to having a quiet, uneventful night at home alone.

"Ugh…. I'm exhausted." Arizona said as she plopped down on the couch.

"Really?" Callie said a little pout forming on her face.

Arizona looked at her with a sheepish grin knowing exactly what her girlfriend was looking forward to on their quiet night.

"Calliope, you know I am never too tired for that". Arizona said leaning in and kissing Callie on the lips. She pulled her in closer to deepen the kiss. Callie moaned into the kiss taking Arizona around the waist.

Suddenly, Ring! Ring! Arizona's cell shrieked.

"Seriously?" Callie groaned.

"Hello?" Arizona answered.

"Uh… Arizona?" the voice on the other end questioned.

"This is she. Can I ask who's speaking?" Arizona said. She gave Callie a confused look. Callie just looked annoyed at the interruption.

"It's uh…. Kate." The voice said nervously.

"KATE? Where are you? Are you ok? What's wrong?" Arizona asked panicked.

"Yeah, yeah Ari, I'm fine. I'm actually in Seattle… I was hoping I could see you? I kinda need a place to stay just for a little bit until I figure out some stuff and I know we haven't talked in a while and I know I've fallen off the face of the earth for a little while but I need someone now. I didn't know where else to go or who to turn to and you said…."

"Kate, Kate. Calm down. I'll give you the address to where I live and just call me when you get here and I'll let you in. " Arizona told the girl. "Kate, listen, we'll work everything out once you get here ok?"

"Ok." Kate replied. "Hey Ari?"

"Yeah?"

"Thanks." And with that Kate hung up the phone.

Arizona just looked at the phone once the other end went dead. She knew she had a lot of explaining to do for Callie. She had wanted to tell her about Kate, but never could. She always thought that the topic of Kate would never arise. Kate had been gone for so many years and Arizona always thought that she had plenty of time to tell Calliope about this part of Arizona's life that she never rushed with telling her girlfriend anything about the girl that she had just gotten off of the phone with.

Callie just stared at Arizona waiting for an answer.

"Do you care to explain?" Callie asked looking at her girlfriend with a very annoyed look.

"Uh… well… uh… Callie… Kateismysister." Arizona rushed out.

"What? Arizona slow down. Whatever you have to tell me it can not be that bad… seriously."

"Ugh… ok Calliope, ok. The person on the phone just now was Kate. Kate… is… my… sister. And she is in Seattle and I haven't seen her since Daniel died… she just sort of lost it and ran away and my family looked for her for a really long time but we couldn't find her… she took Daniel's death really hard… she is the baby and she and Daniel were insanely close. And I know, yes I should have told you but I didn't think she'd ever show back up…" Arizona rambled hoping it would take the wrath of Callie that she knew was about to blow up.

"When will she be here?" was all that came out of Callie's mouth as she stood up to start picking up around the apartment.

"What?"Arizona asked, surprised that Callie was being this calm.

"When will Kate be here, as in here at our apartment? I mean really Arizona it's not that hard of a question." Callie stated as she got up off the couch and began cleaning up for their visitor.

"You aren't mad? I expected yelling and you being angry and there isn't any of that"

"Arizona, you didn't think the situation would ever come up… yeah I'm mad because you never told me you had a sister but… you didn't think it would be an issue… you didn't think there would be anything to tell so I'm letting it go. I also am not going to get mad because I like where we are and I'm not going to get angry over something this petty." Callie said taking her girlfriends hands. "I love you and just next time tell me please."

"I love you too… Calliope you are awesome. Absolutely… awesome"
