A few minutes later they heard a door open at the end of the hallway and they both looked over and saw a tall, thin girl with dark red hair walking out of Mark's room wearing a guy's button up dress shirt and nothing else. Mark was chasing after her. "Addison, seriously." She looked back at him, smirked, and continued walking.
Derek got a look of disgust on his face when she walked into the room, while Meredith just sat there looking confused. "Well, isn't this cozy," Addison said as she looked at Derek who still had his arm around Meredith.
"Addison, what are you doing here?"
She walked over behind the couch, rested her elbows on the back between Meredith and Derek, and leaned over. "What's it to you? It looks like you've been making yourself quite busy."
"Addison, please," Mark said from the side of the room.
"Addison, seriously. Go walk your whore of a self back to Mark's room and spread your legs—that is what you do best, isn't it?"
"Ooo, ouch," she said, sarcastically as she looked over at Meredith. "Derek, aren't you going to introduce us?"
"You're not worthy of an introduction, Addison," he said coldly to her as he turned his focus back to the TV and tightened his grip on Meredith's shoulder.
"Fine, then. Hi, I'm Addison Montgomery," she said extending her hand out to Meredith from behind the couch.
"Uh, hi. I'm Meredith Grey."
"Oh, Ellis Grey's daughter. I remember Derek saying her daughter was his organic chemistry lab section. I'm a TA in that class as well, for a different group of students, but I'm sure you're too busy lusting after Derek to notice."
"Addison, that's enough out of you," Derek said as he looked at her with a warning glare.
"So Meredith, do you make a habit of sleeping with your TA's? Or is Derek just an exception."
Before Meredith could say anything Derek took Meredith's hand and walked out of the room and back down the hall toward Derek's bedroom. "Addison, go back to Hell where you belong."
Derek and Meredith walked back into his room and he closed the door behind him as he let out a sigh. "Meredith, I'm so sorry." Meredith just stood there, kind of staring out into space, looking confused, hurt, and embarrassed. "Meredith?"
"What the…who is she? Where does she get off calling me a whore?" A tear rolled down Meredith's face as she took a seat on Derek's bed.
He walked over to her and kneeled down on the ground as he wiped the tears from her cheek. "Meredith, what she said to you was totally uncalled for. She's a horrible, horrible person. She's just jealous and angry with me, and so she's taking it out on you."
"What? Why though?"
Derek got up off the floor, took a seat next to Meredith, and took her hand in his. "Addison and I used to date—we were engaged actually, up until a month ago." Meredith's jaw dropped. "We met in college and started dating our senior year, and then we both came here for med school. A year ago I proposed to her—it seemed like the next logical step. We never really got very far with wedding plans, because we were planning on having a really long engagement—we figured we'd get married between med school graduation and starting our internships." Meredith started to silently cry, afraid that Derek was using her as a rebound girl. He saw her tears and wiped them away. "Anyway, about a month ago I was supposed to go spend a weekend in Manhattan with my family since it was the last time I'd be able to get away before fall semester started. My mom called me the afternoon I was supposed to leave and said that my dad was called to a business meeting out of state and she was really sick, so I shouldn't bother coming. So instead of going to the airport after work I came back home. When I came back to my apartment I could tell something was different—nothing was different, everything was the same, but I still felt that something had changed. I walked through the apartment, dropped my suitcase off in my bedroom, and went to go into the bathroom. I heard the shower running so I knew Mark was in there, but I went in anyway. I walked in and realized why I felt something different when I came home that day—inside the bathroom, in the shower, Addison, my fiancée, was cheating on me with Mark. They saw me, I saw them, and I turned around and walked out of the apartment. It was just so common and dirty. From that moment on she meant nothing to me. It's unforgivable what she did."
Meredith could see the tears forming in Derek's eyes as he recounted the story that had probably been the biggest heartbreak he'd ever experienced. "Wow."
"Yeah. And now I see that they haven't stopped sleeping together since that day."
"How can you forgive him?"
"I can't. That's why he is no longer my best friend—he's just the guy I happen to live with. He's just my roommate. Both of our names are on the lease, so unless I want to take a major financial hit I can't get out of it until the end of this year."
"Oh." She stood up and looked at him. "So what am I to you? The girl you screwed to get over being screwed?"
"No, Meredith, not at all. You're like a breath of fresh air. It's like I was drowning and you saved me." She continued to stand there and look at him. "Meredith," he said as he stood up and lightly reached for her arms, "You are not some random girl I found to sleep with as revenge. You're not a rebound. I care about you—more than I actually believed was possible. After only two weeks I feel so much more connected to you than I did with Addison after two months or even after two years with her." He leaned in and gave her a gentle kiss to reassure her.
She looked up into his eyes and could tell he was telling the truth. "And you're sure you're over her?"
"Completely. From that moment she didn't exist to me anymore. The weird thing is, I wasn't even angry that she slept with Mark—I was more hurt that he would sleep with her. I wasn't jealous, or mad—I was just numb. Our whole relationship was based on medicine, and we were just together out of convenience. It never would have worked out with her and me. And as you saw this morning, she can be a heartless bitch when she wants to."
"Is she over you?"
"I think so. I think she was just trying to get under my skin this morning by attacking you. She and Mark are clearly together—it actually makes sense because he's been sneaking around quite a bit recently. Maybe she's mad since I didn't give her the reaction she thought I would when I caught them. But I don't care about them, I care about you. You have nothing to worry about."
Meredith let out a small smile and he wrapped his arms around her and hugged her tightly. "Oh my God!"
"What?" Derek asked her concerned as she pulled away.
"She's a TA in the class, and she knows about us now. This can't be good."
"Don't worry about Addison. I don't think she'd do anything, and even if she did, it wouldn't matter. First of all, everyone knows she and I broke up so I don't think people would believe her, and secondly, what we're doing isn't against any rules, so it doesn't matter."
"Are you sure you're willing to risk your reputation as a TA though for this? What if it turns out to be against the rules?"
"I don't care. All I know is that I want to be with you, so I don't care who finds out, or what people say about us."
She looked up at his face, and nervously bit her bottom lip as she thought about it. "Okay then!" She pushed him back on the bed and started kissing him. He couldn't help but laugh at the way she literally pounced on him, which made her start to giggle as well. She rolled off of him and looked over at him, both laughing almost uncontrollably.
"What a random morning, right?" He said as he tried to catch his breath. They both composed themselves as he sat up and pulled her up as well. "So we're okay? You're willing to see where this goes?"
"Definitely." She leaned in and softly kissed him, resting one hand on his thigh and wrapping the other around his waist.
A/N: So there was a bit of drama for you, and there will be more intense drama on the way. And I really do love Addison, she's my favorite character and my total girl-crush, but I really needed her to be a bitch in the story, so she is. Sorry Addie lovers. She's nice in my other fics tho!
