Once they got off the plane, they returned to their respectable homes. After each person unpacked, they met back at Izzie and Meredith's place to eat something, seeing as it was around six at the time.

After they ate, they found themselves sitting in the living room. It was silent, no one seemed to find a topic of discussion. That silence was broken when Derek began to speak.

"Do you remember high school?" Derek asked looking at Mark and Izzie.

Mark smiled and nodded. "Yeah, we had some good times."

"We haven't heard about any of it though." Addison said with a smirk on her face.

Alex smirked with her. "She's right, I think it's time for some stories."

Addison raised an eyebrow at Alex. "Like story time, Alex?"

Alex rolled his eyes at her.

"Well, what kind of a story do you want to hear?" Izzie asked them, her eyebrow slightly risen.

Alex shrugged. "How about when Mark and Izzie first met each other?" He started to smirk.

Derek looked at the others, avoiding Meredith's gaze. "I introduced them a few months before freshman year ended…"

FLASHBACK

It was a Saturday afternoon. Isobel Stevens was sitting on a bench. Her friend Derek had told her that he has been friends with this guy for awhile, and thought it'd be a good idea if they met. She was a little nervous. She usually gets that way with knowing she'd be meeting someone new.

"Izzie!"

Izzie looked over to where her name had been called. She gave Derek a small smile. There was a guy next to him, he seemed a little attractive, but she didn't think that would matter much. She stood up. "Hey."

Derek smiled. "Izzie, this is my friend Mark. Mark, this is Izzie."

Mark and Izzie shake each other's hands. It was always something people do once they meet each other. Both gave each other a small smile.

Derek awkwardly stood there. Mark and Izzie's hands hadn't released each other's in close to a minute. He cleared his throat.

Immediately they took their hands apart from each other's. Izzie had a light color of pink on her cheeks.

"I'm surprised I haven't seen you around." Mark told her.

Izzie nodded agreeing. "I'm surprised I haven't seen you around either." She told him truthfully.

"Mark and I are going to hang out, so I'll see you later?" Derek asked her.

Mark piped in. "Or she could hang out with us?"

Izzie suppressed her surprise when he said that.

Derek looked at Mark curiously. "Or that." He looked at Izzie. "Do you want to?"

Izzie nodded. "Sure." She gave Mark a small smile.

Derek knew that they had a small thing for each other, but he knew that would pass. It was high school after all.

END FLASHBACK

Meredith looked at Mark and Izzie with a smile. "You two had a thing for each other in high school?"

Mark shook his head with a smile. "No, I mean, she was beautiful, still is, but I didn't really have a 'thing' for her." Meredith, Alex, and Addison looked at him. "Fine, a little, but it wasn't anything big."

"Then." Alex muttered.

Addison looked at Izzie with a knowing smile. "Izzie."

Izzie looked at Addison, then glanced at Mark. After a moment of silence. "Fine! I had a small crush on him in high school, but it wasn't that big of one." She blurted out as she leaned back against the couch.

"Aww, Iz…" Mark said playfully as he put his arm around her shoulders.

Izzie rolled her eyes with a smile.

Derek raised an eyebrow. "When was this?"

"Just freshmen year." Mark and Izzie replied in unison. They looked at each other and both let out a small laugh.

Alex smirked. "Go figure that."

Izzie started laughing as she thought of another memory. "Remember Derek's girlfriend junior year?"

Mark started to laugh along with her. "She was so crazy, I swear."

Derek cracked a smile. "She wasn't that bad."

Mark and Izzie looked at each other as they continued laughing.

Meredith shifted uncomfortably from where she was sitting. She didn't want to hear about Derek's past girlfriend's.

Addison sat up more with a smile. "Do tell."

Izzie smiled. "The first time we met her, we were outside of a café…"

FLASHBACK

Izzie and Mark were waiting for Derek outside of Café Loco, a local café.

"I wonder where Derek is, he usually isn't late." Izzie said.

Mark nodded. "Yeah, but that just means that it gives us alone time Ms. Stevens." He said jokingly as he put his hands on her waist.

Izzie started to laugh as she playfully shoved him away. "Shut up Mark."

"Hey guys!" Derek said. A brunette woman who looked their age was walking with him. "Sorry I'm late, I had to pick up my girlfriend, Celine. You guys don't mind do you?"

Mark and Izzie shook their heads.

Celine smiled brightly at them both. "Hi! You must be Mark, and you must be Izzie!" She shook both of their hands quickly. "It is so great to meet you! Oh my gosh! You two so cute together! Derek tells me you two are really close, that is so great to hear!" She looks at Izzie. "You have a tomboy look, you wear it so well! I never was interested in that style, but maybe I should now!" She thought for a moment.

Izzie's eyes were a little wide. She looked at Mark who was stifling a laugh.

"I'm like, really thirsty! Come on Derek, lets go get our coffees! We'll see you both inside!" Celine grabbed Derek's hand and they quickly went in, mostly because Celine almost started to jog.

Once they went in, Izzie looked at Mark again. "I'm sort of scared to go in now." Izzie said to Mark a little seriously, and a little jokingly.

Mark chuckled. "Come on." He put his arm around her shoulders and they both began to walk into the café.

END FLASHBACK

The whole room was filled with laughter, even Derek was laughing.

"What were you thinking?" Alex asked him.

Derek looked at him with a smile. "She was nice." He looked at Izzie and Mark. "Right?"

Mark smiled. "She was, but sometimes she talked so fast that you couldn't even understand her."

Izzie started to laugh. "I almost missed when she told me that my shoe needed dusting. That was a little strange." She remembering the time when Celine told her that.

"Wow." Meredith said as she looked at Izzie. It was good to hear that this girl wasn't one to be remembered because of his feelings for her. Why did she care though? They weren't dating, besides, it would be bad if they did… Right?

"Any really crazy things happen in high school?" Alex asked curiously.

Mark smiled. "There was this one time senior year when they actually had a water balloon fight after school."

Derek started to laugh. "We all got so drenched that day."

Izzie shook her head with a smile. "Nobody even knows where they got the water balloons."

"How was it?" Alex asked interested. He never usually I this interested, but seeing as how it was about there past, you could sort of understand why.

Mark began. "See, we were just coming out of the school…"

FLASHBACK

Derek, Izzie, and Mark were walking out the front doors of the school when they saw many seniors, and a few juniors throwing water balloons at each other, there were piles of water balloons everywhere. They had no idea who had put them there.

Mark put an arm around Izzie and moved her quickly so a water balloons hit the school and not her.

"Thanks." Izzie said as she looked at the chaos.

Mark looked around them. "No problem."

Derek smirked and put his book bag down. "Let the fun begin." He started to walk away towards a pile of water balloons.

Mark and Izzie looked at each other. Mark shrugged and put his book bag on the ground. Izzie did the same.

Izzie gasped as she felt a water balloon hit her butt. She put her hands on her butt and felt the cold wetness.

Mark looked over at Derek who was now laughing. "Oh, it's on now!" He ran over to a pile of water balloons.

Izzie started to laugh as she saw Mark throw a water balloon at Derek, then Derek to Mark. She stopped laughing when she felt water hit her waist. She looked over at Mark who was smirking at her. "Okay, now that's it!" She ran over to another pile of water balloons.

Now they were in an all out water balloon fight.

END FLASHBACK

Again, the room was filled with laughter.

"I wish my high school had something like that." Addison said with a sigh.

Alex nodded. "Same here."

"You know what I want to hear?" Meredith said. "The day Mark left for college."

Derek glanced at Izzie and chuckled.

Mark rubbed Izzie's forearm with the hand that was around her.

"What?" Izzie looked at Mark and Derek.

Mark and Derek glanced at each other.

Derek started. "See, my mom and my sisters were also at the airport…"

FLASHBACK

Derek's mom, Lydia, pulled Mark into a hug. "We're going to miss you."

"I'm going to miss you all too." Mark said as he released from the hug. He proceeded to hug three of Derek's older sisters. Then he hugged the fourth oldest.

"Bye Markie." The fourth oldest said.

Mark chuckled. "Bye Nancy pants." He released from her hug before giving Derek a manly hug.

When Mark and Derek pulled apart, Izzie grabbed him by the arm and turned him and wrapped him in a hug. "I'm going to miss you." She said muffled into his shoulder.

The hug caught Mark a little off guard but he immediately relaxed into it. He smiled as he closed his eyes and took in her scent without realizing what he was doing. "I'm going to miss you too, Iz."

Nancy and Lydia shared a knowing look.

Izzie raised her head up from his shoulder to look at him. "Call me right when you get off the plane, got it?" She said seriously.

Mark smiled at her. "I got it."

"Promise? Promise me Mark." Izzie asked with a small smile.

Mark smiled at her once again. "I promise."

Izzie pulled him into another tight hug. "I'm going to miss you so much." She whispered into his shoulder.

Mark smiled softly and tightened his grip around her. "I'm going to miss you too." He whispered into her hair.

Flight 1320 was called on the intercom.

"That's me." Mark said as he slowly released from Izzie.

Izzie looked at him, you could se a little sadness in her eyes. "Remember."

Mark kissed her on her cheek. "I'll remember." He released his hands from hers slowly before making his way to the terminal. When he was almost there to walk to get to the plane, he waved to them, more so on Izzie.

Izzie gave him a sad smile and waved goodbye to him.

Mark gave them one last wave before walking to get on the plane.

END FLASHBACK

"Aww." Addison and Meredith said at the same time as they looked at Izzie and Mark.

Mark brought Izzie a little closer to him and kissed the side of her head.

Izzie rolled her eyes and looked at Mark with a smile. After a second, she stood up. "I'm going to get something to drink, anyone want anything?" She asked as she looked at everyone.

"Water." Addison said as she sat back.

"I'll take a beer." Alex said.

Derek nodded. "Me too."

Meredith looked at Izzie. "I'll take a water too."

Mark stood up. "I'll help you with them."

Izzie smiled at Mark and they both walked to the kitchen.

When they got in the kitchen, Addison looked at Derek. "Even in high school they basically were in love with each other."

"I would have never guessed." Alex said sarcastically.

Derek shook his head. "I never even released it."

Addison shook her head at Derek. "That's sad."

Derek rolled his eyes at Addison.

When Izzie and Mark walked in the kitchen, they both looked at each other and smiled.

Izzie walked to Mark and put her arms around his neck with a smile and leaned up and kissed him softly.

Mark put his arms around her waist and kissed back.

Izzie smiled as they pulled apart. She nuzzled their noses. "I never realized how mushy we were in high school."

Mark raised an eyebrow at her. "Mushy?"

Izzie nodded. "Mushy. I just couldn't stand to be away from you." She said as she played with the hairs on the back of his neck with her fingers.

"And you still can't. Am I right?" Mark asked with a smile.

"You're very right." Izzie said when she leaned up to kiss him again, but she stopped midway when she heard a scream.

Mark and Izzie looked at each before taking their arms off each other and walked to the threshold of the kitchen and turned themselves to the left to look into the living room.

Meredith and Addison jumped on the couch as they looked at the spider that was crawling on the coffee table.

Izzie's eyes widened when she spotted it, she then clutched onto Mark's arm.

Mark looked at Izzie amused. "You really need to get over your fear of spiders."

Izzie gave Mark a small glare. "Shut up."

Mark chuckled.

Addison glared at Alex who was looking at her amused. "Just kill the damn thing!" She practically screamed.

"Quiet, you'll disturb the neighbors." Alex said smirking as he took off one of his shoes.

Mark chuckled again. "Alex, we are the neighbors."

Derek nodded. "You are."

Alex rolled his eyes as he got on his knees and went to the coffee table. He raised his shoe up and smashed the shoe onto the spider on the coffee table, killing the spider.

Addison and Meredith sighed with relief as they started to sit back on the couch.

Izzie also sighed with relief. She rested her head on Mark's shoulder and looked up at him. "You're staying the night, right?" She asked him softly so no one would hear.

Mark looked down at her, he ran his finger tips over her cheek. "I don't know what I'd do if I didn't." He told her softly.

Izzie smiled at him.

Alex stood up and put his shoe back on and moved to sit back down where he was sitting before. "Now, anyone up for strip Twister?" He smirked.

Addison took a pillow off the couch and gestured to Meredith to do the same. They then threw them at Alex.

Alex dodged the pillows and looked at the two women on the couch. "Is that a no?"
