On Monday, Callie hesitantly stepped out of her car, and hiked her bag on her shoulder. She was not looking forward to going to school this morning. All weekend, she thought about what Mark had said, she thought about if being with him would make her happy, or if it would be a constant reminder that she couldn't trust him. She hadn't made up her mind just yet, but she knew that she was close to coming to a decision.

Her first class of the day was with Addison, so that was a plus, but the downside, Mark was also in it. Without stopping to talk to anyone, she walked through the halls of Seattle Grace High, and slipped into her class. She breathed a sigh of relief when she saw Addie sitting in her usual spot, texting away on her blackberry. Callie made her way to her seat and sat down in it. Addison finished up her text and put her blackberry down, then looked at Callie.

"Hey, what happened at the party?"

"Mark talked to me, he said he was sorry and that he didn't know that Izzie was gonna kiss him, he said that she just came in and jumped him" Addison nodded and then looked at Callie.

"This is good right? Mark didn't technically kiss her, she kissed him, is it still count as cheating?" Callie could only shrug her shoulders.

"I don't know, I want to believe him, I do, but the smallest part of me doesn't believe him."

"Why wouldn't you believe him, Callie? Has he ever lied to you?" Callie shook her head.

"I guess it's because I've dated guys like him, you know that, and I feel like this time, Mark is different, I really care about him, Addie" Addison swung a arm around her shoulders and squeezed tightly.

"If you really care about him, then you should talk, at least give him a chance"

"I guess your right, he at least deserves that, he was a really good boyfriend." After she said those words, the man of topic walked through the door. He walked in with his head hanging low, and when he brought it up to meet Callie's eyes, she graced him with a warm smile. In that moment, she believed that there was hope.

At the end of class, Callie slipped him a note that said 'Can you meet me outside at lunch? I think we need to talk. xo Callie' Mark held the note close to his chest and watched as she left the classroom.

When lunchtime rolled around, Mark was outside the entrance of the school, waiting for Callie on one of the benches. When she walked out the doors, he shot to his feet and waited until she sat down to sit back down himself. They sat in silence for a while until Callie finally cleared her throat.

"I want to believe you when you say you didn't know that the kiss was gonna happen. I do believe you, but you have to give me some time to process all of this." Mark nodded and cautiously grabbed her hand. He was shocked when she interlaced their fingers.

"I am truly sorry, Callie, you have to know that I would never do that to you"

"I know, and I know that over time, we will be back to normal, just...not yet" Mark nodded silently and rubbed the back of her hand with his thumb.

"Do you still want to go to prom with me? I, I mean, I understand if you don't want to go, but, yeah" Callie chuckled at his uneasiness and smiled at him.

"Yes, I still want to go with you, I bought a dress that demands to be shown off." Mark's grin widened as he listened to her talk.

"I can't wait to see it" Callie leaned closer to him and left a small kiss on his lips.

"I can't wait for you to see it either." she said as she leaned back in for another kiss. Before anything got out of control, Callie stood and walked away, sending him a smirk over her shoulder. Mark sat there for a few more minutes with a smile on his face. How he had managed to get his girl back was unknown to him. But whatever it was, he couldn't help but be thankful that it was there.

The next three that led up to the prom were complete happiness for Mark and Callie. Mark had taken Callie out everyday whether it was day or night. They would do all different kinds of things, go to the movies, dinners, sometimes they would just sit on the hood of Mark's car and gaze out at the night sky. But what they did didn't matter to them, it was the time spent together that brought them real happiness. They had gotten back to the point they had left off at. They were finally back to normal. There were still some kinks in their relationship, one being Izzie Stevens.

Last week, Izzie tried to hit on Mark again, but Callie was there to tell the stupid bitch to back off. To prove her point, Callie grabbed the collar of Mark's shirt and crushed her mouth to his, making sure that Izzie finally got the picture. Mark would never tell her, but seeing her all jealous and territorial was extremely hot. Another kink, was Mark's jealous track. He almost punch George O'Malley for reaching out and rubbing Callie's arm. But, a stern look from Callie told him that his green-eyed monster, wasn't as appealing as hers.

Also during this time, Teddy, Callie and Addie all became quite closer. Soon, it wasn't unusual to see the trio walking down the halls, arm in arm, or see them at the mall shopping together. Callie and Addie realized that they had a lot in common with Teddy. She was hardcore and bad ass and she was brilliant, much like themselves. They decided that they should all show up to prom together, Addie and Derek, Callie and Mark, and Teddy and Alex. Even though Mark still had a bit of a grudge against Alex for taking Callie out on a date, he had to realize that they weren't even dating yet.

Today, the girls found themselves all at Callie's house, while the boys were at Mark's. The limo would be picking them up at 8 and they all needed to be ready. The girls gossiped and did each other's hair while the boys came up with ideas to get themselves laid that night. Callie made it very clear to Mark that she wasn't ready, and he wasn't about to push her. A few hours later, the limo arrived, the boys came along with it. After taking thousands of pictures that Callie's parents insisted they take, they were off. To what they all hoped, was the best night of their lives.
