Mark and Derek were walking into Derek's living room.

Derek was planning to maybe show him a few things, hopefully to jog his memories. He didn't want to push him though. If he pushed him, Mark was most likely going to get pissed off. He didn't really want that to happen.

Mark glanced at Derek. He couldn't get her out of his head. Ever since the hospital, she seemed to be invading his mind. The kiss was even making an appearance in his mind. He hadn't focused on it before, but there was something sweet about that kiss, the way her lips felt on his. He didn't think about it much until now.

Derek sat on one end of the couch. He didn't know how to approach talking to him about reminding him of the past five years. He didn't know if Mark wanted to know right now, but Mark was getting married in a month. As soon as he could try to remind him, he would have to take that chance, and that would be now.

Mark wanted, no needed to ask about her again. He couldn't just have a woman plastered on his mind without knowing who she is. He saw that Derek might want to say something, but right now, before his friend said anything, he had to ask about that blonde haired woman again.. "Who was that woman? At the hospital." He asked again for the second time that day, hoping to get an answer, sitting down at the other end of the couch.

Derek looked at him surprised. He didn't think he would ask about Izzie again. Though she did kiss him, but he wasn't really expecting that. He couldn't tell him right away about her, if he did, then he might not know what to say. He thinks it'll be to much for him to handle if he finds out right now. It took him a few moments to think of a reply. "I want to tell you, but I can't. That is something you'll have to remember on your own." He told him.

Mark sighed. He knew Derek was right. There were things he was to be told and reminded of, and others that he needed to remember on his own. He knew that, but it didn't stop him from wanting to know. He nodded. "I understand." He said glancing down at the floor.

Derek looked at Mark. He had to think of something to get him to agree to look at something to try to get his memory back, or at least part of it. Anything would be good, no matter what is was that he remembered. "I don't know if you want to do this right now, but do you think you're up to trying to get your memory back?" He asked a little nervous about it.

Mark stared at the ground for a moment before starting to nod. "Yeah, I'm up for it." He didn't know why he wanted to know so bad. All he wanted to know what her name was. He just wanted to put a name to that beautiful face that that woman had.

"Great. I'll be right back." Derek said standing up and walking towards his room. He thought of something simple that he might remember, it was from a year ago though, and he wasn't sure Mark would, but it was a picture that he thought was an easy one to explain to him.

XXXXXXX

Izzie held a mug of coffee in her hands. It was warm beneath her fingers. It made her feel warm, but that kind of warmth she wanted was from the one man that didn't even know her name. She didn't know how he was at this very moment. She didn't know if he remembered anything, whether it be a flashback from a conversation they've had. She wanted to know. She wanted him around her. He couldn't be, not right now. She closed her eyes. She wondered how much of this she could take.

"Do you want to talk?" Addison asked her gently. She was sympathetic towards her friend. She couldn't even imagine what she was going through at the moment.

Meredith looked over at Izzie. "We're hear to listen if you need to." She told her, reassuring her that they were there. If she needed to cry or talk, they would be there, they were friends, together till the end. Of course that's what Mark and Izzie were suppose to be, but now, who knows.

Izzie nodded, showing that she had heard them, but she didn't speak. She didn't feel like talking. All of her emotions felt so strong within her that it blocked off her path from speaking. It blocked off moving, and she didn't even drink any of her coffee. She felt as if her world came tumbling down. Without him there, she didn't know if she would be able to even live.

Derek walked back into the living room where Mark was sitting. He held a picture in his hand. He hoped that it jogged something, though he knew it wasn't a big thing, and something like this wouldn't jog it as much as other things would, but right now, this was all he could really think of. He sat down on the spot of the couch that he was sitting at before.

Mark glanced over at him and saw the picture in his hands. He raised an eyebrow. "A picture?" He wasn't sure why, but a plain picture he just couldn't think of as a memory starter. He knew that it must have been recent at least figuring that he never was a big fan of posing for pictures.

Derek nodded and handed it to him.

Mark looked down at it. It was him sitting on a stoop near some lake in the woods, somewhere outdoors, looking down at his phone with a small smile on his face. He guessed that he was texting in this, but to who? When was this? Why was he even in the freaking outdoors?

Derek watched as Mark took the picture and scanned through it. "You, Finn, Addison's boyfriend, and me went camping around a year ago. We basically forced you to come. You didn't want to be away from-" He cut himself off. He couldn't say who it was, then he would ask who that was, and then he would have to tell him that it was the blonde woman at the hospital, but he couldn't do that. He knew he couldn't.

Once those words left Derek's mouth, Mark's head shot up. In him, something just jumped, like it was the most important thing in his life, but when Derek didn't finish his sentence, he wished he would. He wanted to know what, no, who he was going to say.

Derek cleared his throat, ignoring the last thing he had just said, hoping Mark would too. "It's just a picture of that." He said trying to clear what he said before up. "I took that because you were texting and talking to-" He cleared his throat again. "Someone, instead of fishing most of the time." He explained to him.

Mark closed his eyes once Derek cleared his throat for the second time. He knew he wasn't going to say who, it might have been her. Maybe that's why he didn't say who, it was her. It wasn't long before his eyes looked back onto the picture and he felt as if time froze in place. It wasn't the first time he felt that happen that day as something flashed into his brain.

FLASHBACK

Mark read the text that was on his phone. He was thankful that they got service out there, or else he wouldn't be able to talk to her, and he wasn't willing to do that.

What's it like out there?

Mark glanced up at the woods. There was nothing interesting about the outdoors, and he wasn't going to call it great, that was what Derek would call it, and Derek would mean it honestly. Very woodsy, even found a frog. He replied back to her, might as well bring in some humor seeing as how he wasn't enjoying this experience filled with nature.

I see. The ribbit animal.

A small smile formed on his face. She had such a childish quality sometimes, like when she looks at the stars. Her eyes look as if they had all the answers, and he loved that about her.

Derek looked at Finn. He wasn't that surprised Mark was texting her, but this was a guys weekend, though he should of guessed this would happen seeing as how he didn't want to leave her, even for a day or two. "Where's the camera?" He asked Finn with a smirk on his face. If Mark was going to do this the whole trip, mine as well have blackmail, or maybe just tease him about it when he starts talking about his hair. He couldn't help that it looked perfect, it was natural, and he absolutely didn't use mousse of any kind.

Finn looked at him confused, but he wasn't going to question it. He looked in back of them where the case for the digital camera was. "Right…" He bent down and picked it up. "Here." He stood up and handed the case to Derek, curious to see what he was going to do.

"Thanks." Derek said opening the case and taking out the digital camera. He held it up so he could get a good view of Mark on the stoop with his cell phone in his hands. When he thought he got the right shot, he smirked and clicked it to take the picture.

Mark looked up to see Derek with a digital camera in his hands. He raised an eyebrow at him. All he saw was a flash from the corner of his eye, and now he saw Derek with a digital camera in his hands. "Did you just take my picture?" He asked, glancing down at his phone to see if she had texted him back yet, when he saw she didn't, he looked back up at Derek, curious to know what he was going to say.

Derek shrugged with a smirk on his face. "Blackmail." He said simply. He didn't think anything else needs to be said about it.

Mark furrowed his eyebrows in confusion. He didn't understand Derek's mind sometimes, and this was one of those times. How the hell was that blackmail? He really didn't understand it. "How's that blackmail?" He asked genuinely confused.

Derek's smirk started to fade. He glanced at Finn, then looked back at him. "I don't know…" He said trying to think of a reason.

END FLASHBACK

Mark snapped out of his thoughts when Derek shook his shoulder a little bit. He looked at him, he wasn't sure what to make of what he just remembered. He was wondering who he was texting, he was thinking it was a woman, but he wasn't exactly sure about that, it was just a feeling. He also wondered why Derek would think that'd be blackmail.

"You okay?" Derek asked concerned. It wasn't the first time Mark had stared and frozen in thought. He thought that maybe he remembered something, and he wasn't above asking.

Mark nodded, staring at the picture, thinking. "Yeah, I'm fine." He said knowing he wasn't being completely truthful. He was just stuck on the questions popping into his mind, ones from before, and ones that are just popping in now.

"Did you remember something?" Derek asked curiously. He was hoping that this wasn't pushing, but he didn't think it was, it was just a question. One question like this wouldn't hurt, at least he thought so.

Mark glanced at him. He didn't want to say he remembered something. It wasn't significant, if it was he would say something, but it wasn't, so why even bother, right? He didn't feel like staying and being brought more pictures or anything right now. "It doesn't matter." He stood up. "I'm going to go for a walk."

XXXXXXX

Izzie stared at the wall in front of her. She kept the mug in her hands, it was slowly cooling down. She could feel it as she held it. She closed her eyes, trying to remember this morning, the way he kissed her with a smile on his face as she woke up, the way he told her he loved her from the time he woke up to the time he had to go. If only he hadn't of left this morning, she wouldn't be feeling like she.

She could feel them watching her. She felt as if she was being closed in, like they were suffocating her as they stared at her. She wanted to be alone. She just wanted to get away from this. She put the mug of now cool coffee on the coffee table. She stood up slowly. "I'm going to take a walk." Izzie said quietly.

"Do you want us to come with you?" Meredith asked. She was worried about her friend, and would be there for her when she needed it.

Izzie shook her head and started to walk out of the living room.
