Meredith held Jamie's hand to leave the school grounds and go home. Charlotte was on the other side of Jamie and the rest of their friends had already left.

"I think we are safe to walk with the cheers" they heard behind them.

"Maybe you should wait a couple of blocks, Mark" Charlotte replied.

"Why he has to wait?" Jamie asked looking at Charlotte, but instead hearing a man's voice.

"We don't want other boys thinking we have cooties" Derek whispered to him like they were sharing a secret.

"My sister doesn't have cooties" Jamie frowned.

"She has" Derek whispered, winning a glare from Meredith "She can't pass to you, because you are probably a super hero"

"Really?" Jamie ask with his eyes shining.

"Would I lie to you?" Derek teased the boy.

"Maybe" he said "I don't really know you"

"Oh" Derek pretended to be surprised "Derek Shepherd"

"James Grey-Webber" the little boy told him, shaking his hand.

"And the man is whipped" Mark groaned.

"Am not!" Derek argued.

"Yes, you are" Charlotte, Mark and Copper said together.

Derek glared at them, but realized Meredith was giggling, so he decided it was best just to smile at her.

"I think we should get going" Meredith said, breaking eyes contact with him.

"I guess that means we can walk with you" Mark said.

They all rolled their eyes at him.

"I'm just saying" Mark stated "And... I am going on a date later"

"What?" a lot of heads turned to them.

"With Lexie?" Meredith was the first one to ask.

"No, with Addison" Mark said with a serious tone.

"Are you crazy, empty head?" Charlotte said, slapping him on the head.

"Now, I think I am" Mark said, passing a hand on his head "And I was kidding, I am going on the date with Lexie, asked her today"

"How was it?" Meredith asked curious.

"It was like..." Mark started telling.

"Hey, Lexie" Mark called before the cheerleaders got in the gym. She had Izzie and Arizona by her side.

"Mark" she blushed a little, which made Mark grin.

"Can I talk to you?" Mark asked, his hands were sweating.

"Sure" Lexie said, giving Arizona and Izzie a look that said she wanted to be left alone with the handsome boy.

When the two of them were alone, Mark gave her a flower he was hiding "That's for you"

Lexie took the flower and made a face "It's a plastic flower"

"I didn't want it to die and I wanted to surprise you" Mark told her.

Lexie beamed "Thank you, Mark, that's very nice of you"

Mark stared at her "Do you want to, you know... Er... Go to a movie with me or something?"

"I would love to" Lexie kissed his check "Pick me up at seven"

Mark finished telling with a blush in his check, looking for Derek's and Cooper's reaction, noticing they were both holding their laughs.

"Stop you two" Mark snapped.

"Sorry" Derek said.

"It won't happen again" Copper completed.

They were still holding their laugh when they heard the girls chucking.

"You two also think that's funny?" Mark groaned.

"Sorry, Mark" Meredith told him.

"We just... Weren't expecting that from you" Charlotte completed.

"Well, I'm like that, full of surprises" Mark told them, still pouting, like he would do the rest of the walk.

"Char?" Cooper whispered in her ear. She looked at him "Do you want to go to Mark's party with me tomorrow?"

She just nodded at him as he left grinning like a fool.

"Meredith" Derek said, running to her right side, since she had James on her left "We are still on for tonight, right?"

"Oh... I don't know" Meredith said "What are you referring to?"

Derek looked at her with wide eyes "Did you forget that we are going on a date?"

Meredith laughed at his face and Derek could breath again, realizing she was playing with him.

"Don't do that again" he said "I believed you"

"Think about that, before telling my little bro that I have cooties"
