Hey-o. So, I got a great response to the last chapter. A few of you had already guessed that Sawyer was with Alex, so kudos to you guys. Those of you who were taken by surprise, I got a mixed bag of happy and not so happy with the pairing. But I'll be honest in telling you that after Callie and Arizona, Alex is my next favourite character on Grey's. So if you're not a fan… well, hopefully you will be when I'm done writing about him.

Arizona was fuming. Angry didn't even begin to cover it. She was having the worst day. Literally. People said that all the time but they rarely meant it. But yeah, today was going to rank in her top ten. No question.

Somewhere, deep down, she was aware of the fact that what she was most upset about was this situation with Timothy. But that was just so huge that her brain was having trouble processing it. So instead, her brain was fixated on the image of her little sister, lying half naked, underneath her protégé. Her little sister, who had lied to her about seeing anyone, was sleeping with her man-whore of a student.

It was so much easier to just fixate on that.

It also meant that Arizona's urge to yell at someone had doubled, and she still had no outlet. She was still in that place of white-hot anger that meant she wasn't ready to sit down with Callie and have a rational conversation. Which was what Callie would want. And simply barking at interns for the rest of the day wasn't going to give her that cathartic release. So as she stormed through her PEDS wing, Arizona had an idea. Callie vented to him all the time, so why couldn't she? They were friends – mostly. And he wasn't exactly a stranger to occasionally being yelled at by her. So with her mind made up, Arizona set off in search of Mark Sloan.

She found him in the first place she looked. The attending's lounge.

"Mark," she barked, waking him from his reverie of coffee, danish and trashy tabloid.

He looked up. "Are you okay? I heard you passed out."

"I'm fine," Arizona replied automatically.

"You don't look fine," Mark countered, raising an eyebrow. "You look pissed."

"I am," Arizona agreed flatly.

"Is Cal in surgery?" Mark asked.

"What? No. Or… I don't know. I don't know where she is," Arizona answered, momentarily confused by the question.

"So Cal's in the doghouse," Mark inferred. "If you're venting to me it means Callie's in trouble."

"What? No," Arizona shot back, her irritation climbing at his attempts to analyze her. If she were actually upset with Callie, she'd go to Sawyer. Not Mark. "I walked in on Sawyer and Karev," she burst, deflecting Mark's attempts at reading her by jumping straight in to the root of her problem. One of her problems.

"What?" Mark asked flatly. "Karev slept with Sawyer?"

"I knew she was seeing someone," Arizona bit back. "I knew it and she lied to me. Lied to my face. God. It's like I don't even know her. How could she hide something like this?"

But Mark wasn't listening. He was grinding his teeth and cracking his knuckles. "I am going to break his stupid little face," Mark swore. He brushed past Arizona and roughly pushed open the door without so much as a backwards glance.

Arizona watched him go in disbelief.

That had not been helpful. Not even remotely. How Callie managed to use that man as a best friend was beyond her. Drinking buddy, sure. That she got. But as a sounding board – he was next to useless.

Now, more frustrated than ever, Arizona marched back to her office, accepting that she really only had one option left. She paged her wife.

Callie's response to her wife's page was almost instant. She'd accomplished very little in the hour since she'd left Arizona other than staring at the device and hoping that Arizona was ready to talk. She honestly hadn't expected it to happen this quickly. Usually, Arizona liked to vent, and to get everything sorted out in her head before having these kinds of serious conversations. But Callie wasn't about to look a gift horse in the mouth.

Callie knocked before entering Arizona's office. Normally she didn't, but right now, it felt necessary; a little sign of respect for the fact that this was Arizona's space and that Callie had been invited into it.

"Come in," Arizona called.

Pushing open the door, Callie took in her wife's appearance. She did not look like someone who had spent the last hour organizing her thoughts. She looked like she was about to rip someone's head off.

"I need you to know that I - " Callie started, but Arizona put up a hand to silence her.

"No," she said flatly. "We're not talking about that."

"We're… what?" Callie asked.

"We're not talking about that right now," Arizona repeated. "Because right now, I need to yell. And I need you for that."

"Okay," Callie nodded, resigned to her fate. They would talk. Eventually. She knew that. And if Arizona needed to get some yelling out of her system first, she could handle that.

"I walked in on Sawyer and Alex," Arizona shouted. "Naked. And having sex," she added redundantly.

"You what?" Callie asked, completely thrown. She thought Arizona wanted to yell about Timothy. Shit. This day had just gotten a whole lot more complicated.

"I mean, not naked naked, their pants were still on, but that's not the point, Callie," Arizona rambled as though Callie had insisted that it was in fact, the point. "If I'd walked in a few minutes later they'd have been completely naked. So we should just be happy I interrupted them before they could get to the good part."

"Um, right, yeah, okay," Callie nodded quickly, eager to agree.

"Karev, Callie. Alex Karev," Arizona continued. "Sawyer is sleeping with Alex Karev. That's almost as bad as sleeping with Mark. The man is a rude, aggressive, inconsiderate man-whore jerk-face!"

Arizona took a deep breath. "And she lied to me, Callie. She lied. I asked her if she was seeing anyone and she lied."

"She lied to me too," Callie confirmed, quick to make sure Arizona didn't think she had been party to keeping another secret from her.

"I feel like I don't even know her," Arizona confessed, and Callie noted that she was losing steam. That had sounded less angry and more defeated. "And she clearly doesn't trust me enough to share anything important. We told her about the baby!" Arizona shouted, as tears started to course down her cheeks. "Just her, she's the only one we told. I thought we had that kind of relationship. But obviously she doesn't feel that way. She lied to me. About her relationship. About my," she bit back a sob. "About our brother."

At this, Callie rushed forward and gently grabbed her wife's forearm. "Arizona," she tried softly.

"You lied to me too," Arizona whispered.

"I never lie to you," Callie swore gently.

"But you knew," Arizona argued.

Callie guided Arizona back to the couch against the wall. As they sat, she pulled a folded up piece of paper from her lab coat pocket. "I got this about a minute before Meredith came to tell me you'd fainted," Callie explained.

Arizona unfolded the page and stared at it for a minute, taking in the DNA profiles.

"You ran a DNA test on Tim and Sawyer?" she asked.

Callie nodded. "Sawyer figured out who he was a few weeks ago, but she didn't say anything. I think she wanted to though because when I came late to our trial appointment last week I overheard them arguing. That's how I found out. And I was never going to keep it from you. But it just seemed so insane that I didn't really believe it could be true. So I ran the DNA test, and got it back today."

"So you never lied to me?" Arizona asked, still staring at the DNA report.

"Never," Callie repeated. "I just wanted to be sure. Because if I told you Tim was alive when he really wasn't, that would have been awful. And if that DNA test had come back negative I would have told you that my trial patient was impersonating your brother. I just wanted to know what we were dealing with."

Arizona slumped back against the couch as relief flooded through her. "You didn't lie to me," she whispered.

Callie grasped her hand.

"Sawyer lied to me though," Arizona continued.

"I think she wanted to tell you," Callie replied. "But Tim told her not to. He told her, told both of us that you'd be better off not knowing. That it would be dangerous if you found out. The fact that he's alive is classified information. He said we could be considered a threat to national security. I think Sawyer was trying to protect you."

"Whose side are you on?" Arizona asked, incredulously.

"Yours," Callie swore quickly, giving Arizona's hand a squeeze. "I love you," she promised.

Arizona sighed and closed her eyes. "I love you too."

When her eyes didn't open immediately Callie laid a soft hand on her wife's cheek. Arizona leaned into the touch.

"Hey," Callie said gently. "You've had a rough day. A long day. And when Hunt heard you fainted he said to send you home. I just have to round and then I'm done too."

Arizona opened her eyes. Callie kept her hand in place.

"Do you want to wait for me here? Or do you want me to meet you at home?"

Arizona blinked. "I want to go home."

Callie nodded. " 'kay, Sofia?"

"I'll take her," Arizona replied.

Callie nodded again. That sounded like a good idea. Arizona's day had been filled with deceit and lies. Some cuddles with the most innocent and pure thing in their life probably wouldn't hurt.

Callie leaned in and pressed her lips to Arizona's in a soft kiss. "World's fastest rounds," she promised, pulling back slightly.

Arizona finally managed a little smile. "Thank you," she breathed.

Sawyer leaned against the sink in scrub room. She was scrubbing out, having just assisted on an absolutely textbook craniotomy with Lexie. They were the only people left in the scrub room. Taking a minute to survey her best friend, Sawyer let out a sigh. She could at least do this right with Lexie.

"Yes?" Lexie asked with a chuckle, hearing Sawyer's sighs.

Sawyer bit her lip. "I'm seeing Alex," she said slowly.

Lexie turned to face her. "Karev?" she asked.

Sawyer nodded.

"Tonight?" Lexie asked, misunderstanding.

"Um, well, yes," Sawyer consented.

"When did he ask you out? Where are you going?" Lexie asked.

"No, Lex, I've been seeing him," Sawyer clarified.

"Oh," Lexie paused. "For how long?"

"Um…" Sawyer bit her lip. "Three months," she mumbled.

"What?" Lexie cried, staring at Sawyer. "Three months?"

Sawyer thought a moment. "Closer to four actually."

"Four… How is that even possible?" Lexie cried again. "No. You could not have had a boyfriend for the past four months that I didn't know about. We live together."

Sawyer shrugged. "You stay at Mark's a lot. Sometimes you're at the hospital. Or Alex and I stay at the hospital. Or his place if April and Jackson aren't home. And sometimes we're just… quiet."

Lexie gaped at her.

"And he hasn't been my boyfriend for four months," Sawyer was quick to continue. "When it started… He always flirted with me because I'm Arizona's sister, so he knew he could never do anything. So it was just fun. But then… we rocked this surgery together so we got a drink, or, a lot of drinks to celebrate and we ended up sleeping together. At first, it was just sex. But then we would talk after, or get dinner after. And I wasn't seeing anyone else. And I realized I didn't want to see anyone else."

"You realized you were dating," Lexie clarified.

Sawyer nodded. "And that we wanted to be dating," she added.

"Why didn't you say anything?" Lexie asked.

"We didn't want to say anything before we knew what… we were," Sawyer tried to explain. "I was worried about what Arizona would say. He was even more worried about what Arizona would say. So it wasn't like we were going to tell her that we were having casual sex. And then when we started to realize that it was becoming something more… I don't know. I think we didn't want to jinx it."

"I guess I get that," Lexie nodded. "Mark and I kept our relationship a secret when we first started dating so that Meredith and Derek wouldn't find out."

Sawyer smiled, grateful for the understanding.

"So what caused this little round of truth telling?" Lexie asked.

Sawyer wiped at her face. "Arizona walked in on us in an on-call room today."

Lexie bit out a laugh. "Excellent way to tell her, Sawyer."

"I know," Sawyer sighed.

"You're gonna be in so much trouble," Lexie laughed, throwing an arm over Sawyer shoulders.

A loud bang sounded against the door to the scrub room.

"What the hell was that?" Lexie asked.

Callie was doing her best to make good on her promise to Arizona to finish her rounds with lightning speed. And she had managed to finish in under an hour. She was hurrying to grab her things from the attending's lounge when she was momentarily side tracked. Mark was pacing outside of OR 2. Exactly the same way he had been when she'd passed him half an hour ago.

Knowing that she'd probably regret this later, Callie stopped. "What are you doing?" she asked.

"Waiting for this stupid surgery to finish," Mark huffed.

Callie glanced at the board. "Why are you waiting on a pediatric parathyroidectomy?"

But she received her answer in the form of Alex Karev, pushing open the door to the scrub room.

"You," Mark spat, grabbing Alex by the front of his scrubs and pining him against the door to the scrub room opposite the one he had just exited.

"Mark!" Callie shouted.

"Get off me!" Alex shouted.

"I told you… I was very clear," Mark said, lifting Alex off his feet and shoving him back into the door. "Not to touch her."

"Mark, what the hell are you doing?" Callie demanded.

"Back off man," Alex replied harshly. "She's a big girl. She can make her own decisions. Seriously. Get off me," Alex repeated, grabbing Mark's arm and freeing himself with the practiced ease of a wrestler.

"He slept with Sawyer," Mark accused, and as Alex freed himself from the door, it burst open to expel Lexie and Sawyer.

"Mark!" Lexie scolded.

"He slept with her!" Mark repeated.

"They're together," Lexie clarified.

"What?" Mark replied indignantly. "No. He's not good enough for her."

"Don't you think I know that?" Alex spat back.

"Shut up. Both of you," Sawyer snapped. "Alex, don't talk like that. And Mark. This is my life. And Alex makes me happy. So back the hell off." She took Alex's hand. "C'mon," she said, tugging him along with her.

Callie finally laughed. "Wow," she chuckled as she shook her head. She pushed past the gaggle of nurses and interns that had stopped to watch the show. At least she could return home with a story that was bound to make Arizona smile.

I was a very good author this week and got a lot written for this. So yay for that. But I have 2 papers and a presentation in the next two weeks; so unfortunately, the update pace will most likely slow a little over that period of time. As always, I will do everything in my power to keep this updated as regularly as possible. So until next time, leave me a review my friends!
