Haha so I've noticed that the timeline for this story is all out of wack. So ... I apologize. :P Basically, Callie and George are married, Izzie is back at work and doing surgeries ... and you'll learn about all the other stuff in the coming chapters. :D Thank you for continuing to read and review, you guys rock.

Chapter Ten

"Who are you sleeping with?" George demanded in a whisper as he leaned over towards Izzie. That morning Izzie had returned about a half an hour before they had to go to work; which only meant that she had actually slept at the house of whom she was sleeping with. From what George could remember about Izzie, it was that she liked bringing people over, not sleeping over at someone's house. Something was definitely up, and George was determined to get to the bottom of it.

From her side of the table in the cafeteria, Izzie asked, "Why so interested?"

George looked down at his plate of food for a moment and then back up. "Cause … you're my friend, and friends tell their friends who they sleep with."

Izzie flashed him a strange look. "Sometimes they don't." She reasoned. It wasn't that she was ashamed of who she was sleeping with, because she actually wasn't. George merely didn't deserve to know. Plus, it was way more fun this way.

George looked up at her with a heartbreaking frown, and a few days ago Izzie would have crumbled under such a look, now however, she went into defensive-mode. "Don't you dare give me that look George. You got married to Callie without confiding in your so-called friends."

George opened his mouth before shutting it again, looking very much like a fish. Izzie straightened up in her chair a little, knowing full well that she had won that battle.

George then pulled out a ten dollar bill and handed it to Cristina. Cristina took the bill with a triumphant grin. "Hey, at least you tried 007."

Izzie's mouth dropped a little. They had a bet going on about her sex life. The nerve. Izzie couldn't help but wonder though, what their reactions would be if they actually did find out who she was sleeping with. Thinking about it now, Izzie was almost tempted to get in on that bet. They'd never in a million years guess, so it'd be an easy way to make a few extra bucks.

It was then that Izzie noticed Callie a few feet away take a seat next to the woman in question. Meredith followed Izzie's eyes, and noticed the same thing she did. She took that as a sign that maybe she should steer the conversation away from Izzie's sex life. After all, with the way that Izzie was looking at Addison right then, Cristina or George would probably see that something was up with the two.

Izzie was suddenly incredibly thankful when Meredith started talking about a surgery. She wanted to be able to watch Addison without being the center of the conversation. Cristina and George were so immersed with what Meredith was saying that Izzie doubted her presence was even known anymore. Way to go Meredith.

Izzie grew a little frustrated when she realized that she couldn't tell what Addison and Callie were talking about. Time to read lips.

"You seem more chipper than usual." Callie said as she plopped in a chair next to Addison, who was busy reading the paper. To Addison, it sounded as if her friend was almost bitter about her happiness. Addison had to remind herself later to have a heart-to-heart with Callie. You know, when they weren't in front of everyone they worked with.

Addison looked up from her paper and smirked. "Yeah?" She asked nonchalantly.

Callie nodded and started to prepare the sandwich in front of her.

Addison shrugged. "Hm", was her response and then went back to reading her paper.

Callie looked up from her sandwich and studied her friend. Something was definitely different. "You had sex!" She yelled suddenly, causing many heads to turn their way.

--

From a little ways down, Izzie caught that statement. She couldn't help but laugh inwardly. Was the red-head that obvious?

"Montgomery got laid, big whoop. It was probably with McSteamy." Cristina said as she turned back around towards her friends. "Anyways, this surgery…"

Cristina went back into explaining, in detail, her incredible surgery that afternoon. Meredith on the other hand, sent a playful smirk Izzie's way.

Izzie rolled her eyes at Meredith although she was strangely grateful to have Meredith in the loop.

Now more than ever though, Izzie wondered what Addison and Callie were saying. She was interested in knowing whether or not Addison would tell her friend who she was sleeping with. Addison was a horrible liar after all.

--

Addison's head shot up. "What? And keep your voice down. This hospital already sees me as Satan's spawn, no need to gloat about me having sex." She looked around quickly, taking note of who was in the room. She spotted Derek at the food stand, but was oddly okay that he had heard. He simply laughed and shook his head. Maybe she was going to be okay after all…

"So you admit it?" Callie asked with a devilish smirk and then took a huge bite into her sandwich.

"Yeah, so?" Addison asked, trying to be nonchalant again. It was actually a very hard thing to do. You don't have sex with Izzie Stevens and act nonchalant, it just doesn't work. Addison couldn't help but wonder if it would it be so bad if Callie knew about her and Izzie.

Okay, so bad would be an understatement. After all, the two hated each other.

"Oh don't 'yeah, so?' me Addison. This isn't Sloane-sex, this is 'I just had some really hot sex-sex'." Callie reasoned as she took another bite of her sandwich.

Addison made a face, and then it dawned on her. Did having sex with Izzie really change her that much? She certainly felt a lot happier, but she in no way thought that other people would notice a change. Hm … very interesting.

Callie saw Addison working something out in her head, and so she nodded victoriously. "See? I knew it. So, spill. Who, when, how, and how good?"

Addison quickly halted all thoughts and looked at Callie with wide eyes. "Um … I can give you the 'when' and the 'how good', but none of the rest. Believe me, you don't want to know."

Callie huffed. "But the who is the best part."

Addison gave her a look that clearly said she wouldn't be saying anything about who the mysterious person was, although she couldn't help but agree; the who definitely was the best part. Callie nodded. "Okay, okay, I give. So?"

Addison took a deep breath. And as she did, her eyes caught the blonde in question. Their eyes met and Izzie flashed a smile her way. Releasing the air in her lungs, Addison smiled. "Last night, and it was a-mazing."

She returned her gaze back to Callie only to see a disappointed look grace her friend's features. "Well that doesn't give me anything. C'mon, I'm looking for details here. How hot of a body did he have? Was he an all night kind of guy?"

Addison suddenly started to laugh. She couldn't help it. She felt so … scandalous, talking to her friend about something that was, unbeknownst to Callie, taboo. At least, it was up until that point of her life. For all Callie knew, she just had some great sex with a great guy. Life certainly was wacky sometimes. Addison continued to laugh as she thought of all this.

"You've officially lost your damn mind Montgomery." Callie said as she raised an eyebrow.

Addison looked at Izzie again and sighed. "Maybe I have." She whispered, although she couldn't help the smile that played on her lips as she looked back at Izzie again. "Maybe I have."
