Title: Make Believe
Summary: She wasn't Addison, and he sure as hell wasn't Derek Shepherd, but in the moment it didn't matter, they were both okay with settling for pretend.
Pairings: Alex/Mer, Mer/Der, Alex/Addison, and mentions of oneside George/Izzie

Authors Note: Alright so my original vision of what would come in the finale was Derek cheating with the mystery woman. Now I'm pretty sure it doesn't happen, but let's just say he does cheat. And Addison leaves for LA, so that's pretty much all you need to know. This is my first Grey's Anatomy fic, so be kind.

Make Believe

Alex Karev was sitting on the couch watching Almost Famous. Ever since Addison left for Los Angeles, he had been keeping to himself and Ava. Ava was his closest thing he had to a confidant, she always talked to him about his life, and he let her. He didn't know why he confided in her so much, he just trusted her. When he wasn't at the hospital he kept to himself at home which was rather easy considering, Meredith had Shepherd, and Izzie…well he really couldn't keep track of Izzie's life right now. The last time Alex heard she was chasing after O'Malley, which he found ridiculous.

No one really noticed Izzie's chase after George, except Alex and Callie. Cristina and Meredith were too wrapped up in everything in the hospital to truly notice. Alex had noticed the morning after when Izzie had come downstairs awkward, and hung-over. He had noticed when she asked him about someone forgetting something, he had told her the usual reason for forgetting a drunken night, you just didn't want to remember. He had watched Izzie's face fall, and that's when it came full circle, Izzie and O'Malley had had sex. He hadn't felt jealousy so much as feeling sorry for her. Izzie could have anyone in the world, and yet she was about to chase after someone who was married, the woman in all honesty confused the hell out of him.

Well really all of the women he had feelings for confused the hell out of him. Maybe that's what he likes about them; maybe he likes the challenge of trying to understand someone. That's what pulled him in with Addison, he's sure about it. After they kissed, she ignored him. That confused him more than he can possibly put into words. He'd never had that reaction before. When Izzie and he had kissed, she had come right up to him to discuss it. But Addison had wanted to ignore it, and pretend it never happened, and she even somewhat punished Alex for it, by not letting him scrub in. He had confronted her, in his typical manner, and she had surprised him yet again by listening to him. He would have expected Dr. Montgomery to give him more punishment for his jerk like manner, but she had allowed him to scrub in. From that moment Alex was hooked, and it wasn't long before unraveling the mystery that is Addison Montgomery had made him smitten. After what seemed like months, he had won her, and then in a moment of weakness royally screwed up. Now she was in Los Angeles, not leaving him anything but a note.

He groaned, he hated to admit it, but he missed Addison. He hated not working alongside her. He hated not being able to tell her that he had chosen his field to be neonatal care. He hated not discussing all Ava's accomplishments with her. He hated not seeing her smirk. But the thing he hated most was not seeing her tiny half smile.

Suddenly the door slammed open, and he heard drunken giggling. He paused the movie, and saw Meredith trying to maintain balance; he waited to see if Cristina, Derek, Izzie, or even O'Malley would be there to support her. When no one came, he walked over to the door laughing slightly to himself. When he reached her, Alex wrapped an arm around her awkwardly to keep her from losing her balance. She continued giggling, as he maneuvered her to the couch, closing the door behind him.

"I'm assuming you didn't drive home." Alex said.

Meredith rolled her eyes, "I'm drunk, not stupid."

"Some would say those two words went together." Alex deadpanned, "So why is your life sucky tonight?"

Meredith shook her head very fast, "You don't want to know."

"I wouldn't waste my breath asking if I didn't want to know." Alex replied, taking a seat towards the end of the couch to allow her to spread out. He noticed a bottle sticking out slightly from her bag, "Give me the bottle."

"No." She answered, and then added, "Besides its empty."

"Meredith." He deadpanned again.

"Noooo it's empty. I drank it all." She said holding her purse close to her chest.

Alex could tell she was a lying. Meredith wasn't a good liar, drunk or sober. He seriously said, "Meredith."

She groaned, and unzipped her purse, taking out a bottle of vodka, "Fine, but for the record I think you are very mean."

He took the bottle, found an old shot glass and took a sip, "For the record I've been told that before."

She glared at him, "How come you get to drink and I don't?"

"Because I need to catch up to you in your drunkenness." Alex explained.

Meredith nodded as if she had full understanding,"Oh."

Alex knew she wouldn't question it. It didn't take much skill to logic things to drunks, and by now Alex was a master of understanding the mind of a drunk, and he wasn't afraid to admit it.

"So you never answered my question." He told her simply.

"About?" She asked.

"About why you're drinking." He replied in a bored tone.

"Guess." She commanded him.

He rolled his eyes, and took another shot, "I don't like games."

"I thought you were a player, if you're a player you've got to like games, it's like in the player requirement book." Meredith explained.

He laughed at her drunken logic, "Says the drunk."

She ignored him, and asked, "You really wannna know?"

He simply nodded, and took another shot.

"Well Derek kissed another girl." She said, "But I'm totally over it now."

It took Alex a minute to understand this revelation. The last he checked Derek was completely in love with Meredith, he was the last one anyone thought would hurt her. Then again Shepherd didn't have the best track record. When he was finally able to respond, he said, "You're not totally over it, you're totally drunk."

She shook her head, "It's over. I slapped him, and broke up with him."

Alex replied back, "After how many shots of tequila?"

"Five." Meredith said easily.

He rolled his eyes, "Nice, let me guess it only kind of looked like Shepherd was kissing another girl."

"No, I was sober when I saw them kissing." She said, "I just took five shots before I did anything."

Alex nodded, "So where's the inappropriate man tonight?"

She looked confused, "Huh?"

"When your life is sucky, you get drunk and sleep with inappropriate men." He repeated, and then added, "Where's the inappropriate man?"

"I must have forgotten him." She replied, as he took another shot. He wasn't so sober himself anymore.

"Good choice." He said, he didn't need some random guy drinking his coffee in the morning. Alex Karev wasn't good at sharing in general, especially in the morning.

"So why are you all alone?" Meredith asked.

Alex rolled his eyes, "I'm not all alone; I've got Kate Hudson."

"And me." She said quietly.

"And you." He agreed.

"How do you feel?" She asked him in seriousness.

He shrugged, "Drunk."

"No how do you feel about Addison leaving?" Meredith asked concerned.

He ignored the question even though he knew the answer. He felt sad, upset, heartbroken, angry, lonely, and so many other feelings, but he wasn't about to tell Meredith that. So he ignored the question.

"Did she at least tell you?" Meredith asked, not noticing him ignoring the subject.

Alex shrugged, "Yeah not face to face though."

"It would probably be too hard. I mean she obviously had feelings for you, if she'd told you face to face, you would have made her stay." She said seriously.

"And that would be bad…" Alex confusedly stated waiting for her to elaborate.

"Because she had her reasons for leaving." Meredith explained.

"Yeah, me. I was the reason she was leaving." Alex said sadly.

Meredith rolled her eyes, "Don't be conceited Karev. It doesn't suit you. There were other reasons. I know it."

"Why did she confide in you?" He asked taking another shot.

Meredith snorted, "Addison confide in me, the adulterous bitch who stole her husband? You're more drunk than I am."

Alex laughed, she had a point. Addison confiding in Meredith was as likely as Alex confiding in Denny.

"So they tore us apart." Meredith said simply.

Alex questioned, "Who?"

"Those recently divorced doctors." Meredith explained bitterly.

"The chief and Adele? I'm sorry, but they have no power over me to tear me apart." He said sarcastically.

"No, you idiot! Derek and Addison." She snapped.

"Maybe Shepherd tore you apart, but it's going to take more than some girl to tear the great Alex Karev apart." He said seriously.

"She wasn't just some girl Alex." Meredith told him, "Any idiot with eyes could see that."

No she wasn't just some girl, Alex thought, he didn't say anything fearing his voice might betray him. He just shrugged.

"And Derek wasn't some guy." She said honestly.

"What makes you think I care?" Alex asked.

Meredith smiled, "Because you haven't left yet."

"I like the vodka shots." He said easily.

"Sure," She laughed, and then continued talking about Derek, "I thought he was the one. I know that sounds stupid, but I did. I never thought I'd think that way about a guy, or hell even give a guy that much power, but I did. I gave him the power to destroy me, but I never thought he would."

"Why are you telling me this?" Alex inquired.

Meredith shrugged, "Because I'm wasted."

"Any moron with ears could see that." He said simply.

"So what do you think?" She asked.

"Of what?" Alex asked.

"Of my little sad love story." Meredith answered.

Alex shrugged, "I think Shepherd's an ass for cheating on you."

"You do?" She inquired.

"Yeah, I mean he's already lied to you once. I can understand one time, but if you care enough about a girl to get a second chance you don't screw it up again." He explained.

Suddenly she leaned in and kissed him. Her breath stinked of tequila, and yet the taste pulled him in like a fly. He explored her mouth with his tongue, and she his, because apparently the taste of vodka was intoxicating to her as well. She wasn't Addison, and he sure as hell wasn't Derek Shepherd, but in the moment it didn't matter. He kissed her neck, and she let out a small moan. She stood up suddenly, and he stood up in sequence. She maneuvered them to her room, and as they reached her bed she threw herself on the bed, he followed. She turned to him pulling off his shirt, and he unbuttoned her top, leaving a kiss at every place the shirt revealed, she continued moaning. It wasn't long before the two of them were wearing nothing, and then it happened, they touched, and for the moment Addison and Derek were forgotten and that was most important.

AN: So tell me what you think, continue or leave it as a oneshot?
