A/N: So yet again, I'm being really slow on updating this. I'm super sorry, guys! I just started college classes for the summer, and they're really demanding, so I tend to forget about this until the weekends. But it would make me really happy if you guys could give me reviews! They're what really motivate me to keep on writing, so please REVIEW!

Storyline Note: This chapter is kind of heart-breaking, sorry in advance! We see Alex going back to his old habits. I know it seems like Alex is really harsh, but trust me, it'll get better!

When he looked at his watch, he couldn't believe that it was 5:30 P.M. already. It made sense that time went by quickly when you were completely immersed in something. Ever since he'd found Ava in the kitchen holding the knife that she'd ran across her wrist, he had become someone different. He had regained a certain set of responsibilities that he hadn't had since he was a nervous little kid, taking care of his mom and his brother and sister. And when Ava was admitted into the psychiatric center, he had tried to forget about her. He tried to forget about her by sleeping around, hoping that he'd wake up one morning and not wish that it was her in the bed next to him. He tried to not imagine what it would be like if they could have had an actual relationship. And he was unsuccessful in all of this, he knew he would be. So he drowned himself in his work. From 7:00 A.M. to 6:30 P.M. he wasn't Alex; he was Dr. Alex Karev. Aside from a few moments in the on-call room with a couple of nurses, he didn't let anything distract him. Bailey had commented on how well he'd been picking up surgical techniques. The Chief had mentioned that he was becoming a stronger resident each day. After work, he'd find himself in Joe's bar, trying to hook up with any girl that had a pulse. It had become routine, and as much as he tried to break out of it, he couldn't let himself go home alone each night.

He set down a few patient charts on the desk that Cristina was sitting behind, typing something on the nurses' computer.

"Any good cases today?" he casually asked. He knew if there was anything remotely interesting going on in that hospital, Cristina would be all over it.

"Don't talk to me." Her eyes didn't leave the computer screen.

He sensed another one of her mood swings coming up. "What's your problem, Yang?"

"My problem is people like you. You think you could do whatever you want, and nobody gets hurt. Well, you know what? People get hurt."

"I don't have time for you to go all Oprah on me right now. I have patients to see." He found it funny how their roles had changed. Cristina never wanted to talk about feelings and things like that. She never talked about them, and he never bothered to listen. He knew that the only reason she'd be telling him this was if Meredith wasn't around.

"Izzie is a good girl, Alex. She might not be my favorite person, but she's a good girl. She's hot, and smart, and to be honest, she's way more than you deserve. And she's helping you deal with whatever your issue is and you're being an asshole."

That statement caught his attention. "Whatever my issue is? What did Izzie say to you?"

"She didn't tell me anything. Stop getting so defensive."

It was clear that Izzie had told Cristina something. And the only issue he'd been dealing with was Ava. Izzie didn't know anything more than that. "Shut up, Yang. And next time, mind your own damn business." He picked up the charts he'd brought with him and walked towards the elevator.

Driving home, he wished so badly it would stop raining. Even just for one minute, so he could actually see where he was going. It usually rained the worst at night, which extremely annoyed Alex. He had taken a new hatred towards car-rides; it was one of the only times he'd spend by himself. It gave him a chance to be alone with his thoughts, and that's what scared him the most. He hadn't allowed himself to think about Ava, or how he'd apparently complicated things with Izzie. He parked his car in front of Meredith's house, and when he walked inside, he headed straight up the stairs towards her room. He knocked on her door before walking inside.

Izzie was lying down on her bed, facing the wall. She had several tissues scattered around her; a scene that looked way too familiar. "Alex, I'm really not in the mood right now" she spoke quietly, and sat up on her bed to face him. He noticed that her eyes were bright pink, and her voice was a little bit coarser than it usually was. She'd been crying.

"What the hell is your problem? Why can't you learn to mind your own damn business for once?" He said it louder than he meant for it come out. The words came out meaner than he meant for them to come out.

She narrowed her eyebrows. "What are you talking about?"

"I cry for one night, two weeks ago, and you can't even shut up about it. And you go tell Cristina, like you guys have been best friends forever."

She looked back at him before finally understanding what he was talking about. "Alex…" she sighed.

He didn't mean to hurt her, but his anger got in the way of anything else he was feeling. "No. I trusted you, or at least I thought I did. I thought you'd be cool about this. But I definitely was wrong."

"Let me explain…" she started, trying to get him to let her talk. The sincerity in her voice, almost made him feel bad for getting so mad at her.

"Just shut up and don't talk to me, Izzie. I'm done dealing with your crap." As soon he spoke those words, he regretted it. But he maintained his composure, and walked straight out of her room, without looking back.

She stood up and followed him as he walked away. "Alex, please, just wait" she pleaded.

He stopped in doorway and turned around so that he was facing her. "I shared something with you that I didn't want anyone knowing, and you go and do the exact opposite. You go and tell something that wasn't yours to tell in the first place. I really thought you were different, I thought you were someone I could trust. I guess I just learned the hard way that I can't" he told her, sternly.

He noticed that her eyes were tearing up again. "You don't mean that" she quietly replied.

His voice was loud enough that he was yelling. "I don't mean it? How do you know that? You don't know anything about me, or what I mean!"

"Alex…" she closed her eyes, which caused a few tears to stream down her cheeks.

The severity in his voice surprised him; he had never gotten this mad at her before. "And when I said don't talk to me, I meant it."

She opened her eyes and looked at him for a few seconds before speaking again. "I'm pregnant."
