For the next three days, Mark and Izzie haven't exactly hung out, or made a time when they would. They had exchanged small conversation at the hospital when Izzie was there to hang out with Meredith, along with Lexie most of those times. She hadn't exactly told them about her and Mark and their discussion about being 'friends,' so she got curious looks from Lexie when they both seemed to be getting along. Though, Izzie knew, Lexie brushed off any suspicion when Mark would make a comment about her and his bed, and with a roll of her eyes, Lexie didn't have a clue. Sad part about that is, Mark was probably being serious with those comments. That thought made her roll her eyes, and shiver, in a way she didn't want to find out.

Now, as she sits down drinking her beer with her two friends at that familiar bar, she sees him walk in with his friend, who is also Meredith's boyfriend.

"Hello ladies." Derek says with a smile as he kisses his girlfriend and takes a seat next to her. "Did we miss anything?"

"Hopefully nothing dirty, because I'd want to see that." Mark said winking at Izzie as he sat between Derek and her.

Izzie just rolled her eyes in response to him, but then looked at Derek. "Nothing but Lexie admitting she can burp the alphabet." She smiled over at her friend.

"It's a talent!" Lexie defended as she slapped Izzie lightly on her arm.

"It's kind of gross, Lex." Meredith admitted with a smile.

"Oh, whatever." Lexie said picking up her beer and taking a drink out of it.

Derek chuckled and watched as Joe came over to the table.

"Would anyone like refills? And what would you two like to drink?" Joe asked Derek and Mark.

"We're good Joe." Meredith said with a light smile, as Izzie and Lexie nodded in agreement.

"I'll take a single malt scotch on the rocks." Mark told him.

"Same here." Derek said.

"Alright, I'll be back in a few minutes." Joe smiled and headed back to the bar.

"Thanks Joe." Derek and Mark said as Joe walked away.

Lexie looked up and saw a sign hanging near the bar door. Her eyes brightened. "Next Friday. Clear your schedules."

"For what?" Izzie asked curiously.

A smile spread across Lexie's face. "Karaoke night."

"I'm not singing." Meredith said holding up her hands a bit.

"Me either." Derek told her.

"Fine." Lexie looked at Izzie. "You are though."

"No, I'm not." Izzie said uneasily. She sang in the shower sometimes, but that was it. And she wasn't planning to sing in front of others anytime soon.

"Yes, you are. You have to be a little more wild Iz." Lexie informed her.

"Yeah, Iz. Be a little more wild." Mark said to her with his signature smile.

Izzie just glared at him in response, causing Mark to chuckle.

"Here are your drinks." Joe said as he placed Derek and Mark's drinks in front of them.

Mark and Derek thanked him.

"Joe!" Lexie said suddenly.

"Yes, Lexie?" Joe asked with an amused smile.

"Izzie wants to sign up early for karaoke night next Friday." Lexie smiled at her friend.

"Really?" Joe asked surprised, looking at Izzie.

"No!" Izzie objected.

"Come on Izzie. Take a walk on the wild side." Mark teased.

Izzie looked at him. "Do you want to do karaoke?"

"No." Mark frowned.

"That's what I thought." She said before looking at Joe. "Lexie wants to sign up early too." She smiled innocently at her.

"Anyone else want to volunteer someone to do karaoke?" Joe asked the rest of them. When he saw them shake their heads, he spoke, "Okay. Have a good night you guys." He told them before walking away.

"I can't believe you signed me up for karaoke!" Izzie said in disbelief to Lexie.

"I can't believe you signed me up for karaoke!" Lexie said with wide eyes.

"I'm just glad I'm not doing karaoke." Derek told them, before picking up his drink a taking a sip.

"I think we're all glad you're not doing karaoke." Mark said with a chuckle.

When the bell above the door of the bar chimed, Izzie subtly looked over her shoulder, not taking a breath, before quickly turning back to the others. Mark noticed, but he brushed it off and didn't say anything. It wasn't his business, whoever or whatever she turned to look at.

"Lexie, you're having eye sex." Meredith said matter of factly with a smile.

"Not anymore." Lexie stood up. "I'll see you all later."

"Go get 'em sis!" Meredith laughed as Lexie lightly hit her shoulder and walked away to the man she was having eye sex with just moments before.

Once Lexie left, Derek leaned over to Meredith and kissed her. "I love you."

Meredith smile. "I love you too." She kissed him.

"At least he's not groping her in public." Mark muttered to Izzie.

Izzie laughed and nodded.

Mark watched her laugh, his own face breaking out into a smile. Her smile was beautiful, one of those smiles that make the room brighten. It was so genuine that it didn't even make you think twice that she was happy, along with that twinkle in her eyes that just enhanced you knowing she was happy.

Izzie looked over at Mark, that same smile on her face, but now, a bit of confusion showed. "What?"

Her voice, brought him out of his thoughts. "What?"

"You were staring." Izzie told him, still confused.

"No, he wasn't." Mark disagreed. He was, he just hadn't of realized it.

"Really?" She raised an eyebrow. "So you were looking behind me with your x-ray vision?"

Mark rolled his eyes. "Don't be ridiculous. And maybe I was staring, but you can't blame me, you are very attractive." He gave her his known McSteamy smile.

"Thanks." She said dryly. "Are you drunk?"

"No, I'm not drunk." He once again rolled his eyes. "Can't I just admire the way you look?"

"You can, but I have to admit, it can get a bit creepy." Izzie said with a hint of a smile on her face.

"It's not like I'm a stalker or anything." Mark made a face.

It was her turn to roll her eyes. "I didn't say you were."

Mark was about to respond when he glanced over at the other pair. "My god. Get a room." He said purposely loud.

Izzie looked over at Meredith and Derek, his hands where they aren't suppose to be while people are around.

"That's a good idea." Meredith said as she and Derek stood up. She grabbed her purse. "We'll see you later." She waved with a smile as her and Derek proceeded to leave the bar.

"I'm glad Lexie was my ride." Izzie said with relief.

"Isn't that your ride leaving now?" Mark asked rhetorically as he pointed to Lexie and the guy she was talking to before leave the bar.

Izzie gave out a small groan. "Now, how am I suppose to get home?"

"Why didn't you take your car?" Mark asked.

"I don't like to drive in the dark." Izzie shrugged.

"Afraid you're going to hit something?" Mark asked with a raised eyebrow.

"No. I just usually forget my glasses when I drive, and I prefer to where them, more so in the dark." Izzie told him.

"Are you far sighted or near sighted?" He asked curiously.

"Far sighted." Izzie replied.

"You know, I could drive you home." He offered.

"Really? That'd be great." Izzie said, grateful.

"Just tell me when you want to leave, and we'll go." Mark told her as he picked up his drink and took a sip.

"Can we leave now? I'm a bit tired." She asked him.

He nodded. "Sure." He took out his wallet to pay for the drinks.

"No, let me pay." Izzie insisted.

"No." Mark said as he put some bills on the table.

"Then at least let me pay for half." She watched as he stood up and put his wallet in his pocket.

"No." Mark said simply.

"Why not?" Izzie frowned and stood up. She picked up her purse and put her jacket on.

"Because I'm not letting you pay." Mark told her before turning around and walking towards the exit.

Izzie rolled her eyes and followed him out.
