A/N: Hello there! I in no way own Sherlock, BBC or Come on Eileen by Dexy's midnight runners

This will be a chaptered fic I think, going from here to different points of their lives. Anywho hope you like it!

It had been a lovely wedding, the vows had been sweet and now John and Mary were officially married. Molly could see them dancing in the middle of the dance floor, surrounded by other happy couples, all in their own little worlds.

She wished that she could have something like that, even after she broke it off with Tom, Sherlock still hadn't made any moves towards her. Perhaps she had been wrong for breaking it off with Tom. He really had loved her.

But at the same time, that day they had spent together after he came back to the land of the living, a friend would never look at her like that, like they loved her. Not the love like friends shared, like her and Mary but like the love between lovers.

She grabbed her glass of champagne and took a large sip.

Seeing as obviously no one was going to ask her to dance she went up to the ladies rest room to freshen up.

Molly looked at her reflection in the mirror. She was dressed in a pretty yellow dress with white polka dots that she had picked out when she went shopping with Mary, her hair was in a French braid, going down her back and she was wearing a pair of black flats that went nicely with her dress.

She opened up her clutch and re-applied her lip stick and eye shadow. Deciding that she looked nice, she exited the bathroom and ran straight into a tall man.

"Oh sorry." She said, moving to go past the man. But as the words came out of her mouth she looked up and saw that it was Sherlock that she had run into.

"Oh Sherlock! How are you? Wasn't the wedding wonderful?" She asked him, smiling brightly.

"Yes, it was quite nice, thank you." He said, smiling.

"Well I'll just get back to my table then." Molly said, moving as to go past him.

"Wait, Molly." He said stopping her.

"Yes?"

"Would you care to dance?" He asked her.

She brightened up instantly. Someone wanted to dance with her! And not that, it was Sherlock bloody Holmes!

"Oh course." She said, grabbing the hand he offered to her. They walked hand in hand to the dance floor.

A new song was starting to play as they went onto the dance floor.

A violin began to play and she put one hand on Sherlock's shoulder as he put one on her waist, their hands remained clasped, a bit higher up.

The music started to play and they started to dance. Sherlock was quite a good dancer, Molly felt a bit embarrassed as she attempted to follow her lead.

They picked up their speed as the song got faster and the lyric started.

Come on Eileen!

"Oh I know this song! I used to love it when I was in high school!" Molly exclaimed. "Come on."

She took her hand off his shoulder and Sherlock removed his from her waist, not sure exactly what she was planning on doing. She grabbed his hand and started to sway them in time to the music, the distance between them now much greater as their arms were stretched out.

Come on Eileen!

She pulled on one of his arms and started to move them their bodies in time to the music, clearly enjoying herself.

Molly started to do a sort of skip walk from side to side, which Sherlock attempted to imitate, failing miserably, Molly laughed.

Too-ra-loo-ra, too-ra-loo-rye, aye

And we can sing just like our fathers

Come on Eileen

Oh, I swear what he means (what he means)

At this moment you mean everything

You in that dress

My thoughts I confess

Verge on dirty

Oh, come on Eileen

Sherlock pulled her closer and spun her around, letting her drift away, before pulling her back in.

She grinned and grabbed his hand again, starting to spin and pulling him along with her.

Sherlock smiled, he seemed out of his comfort zone but he seemed to be enjoying it. They started doing a galloping thing side to side again as the second verse started, although this time they were a little closer together.

Too-ra-loo-ra, too-ra-loo-rye, aye

And you'll hum this tune forever

Come on Eileen

Aah, come on let's

Take off everything

That pretty red dress

Eileen (tell him yes)

Aah, come on let's

Aah, come on Eileen

They moved closer together and he dipped her, laughing. She was glad that he was having fun, she knew that weddings weren't really his thing.

He pulled her up and they spun around in circles, before he spun her again.

Come on Eileen, too-rye-aye

Come on Eileen, too-rye-aye

Now you're full grown

Now you have shown

Oh, Eileen

They we're quite close together now, she was staring into his stormy grey eyes, it was easy to get lost in eyes like those.

Before she knew what was happening, he lowered her head down to hers and kissed her, she started to kiss back and felt his tongue snake its way into her mouth, she granted him entrance. They stopped dancing and were now standing still, arms wrapped around each other in the middle of the dance floor, oblivious to those looking at them and John and Mary's faces of glee.

They broke apart, smiling at each other and laughed.

"Well come on then!" Molly exclaimed, grabbing Sherlock's hands and dancing once again.

They grasped hands and Molly started to spin them around in a circle.

The music started to fade and they stopped dancing, looking into each other's eyes once again. This time it was Molly who initiated the kiss, it was short and sweet and they broke apart to the sound of John and Mary laughing, they turned towards them as Lestrade handed them a ten dollar bill.

"You win." He said, laughing.

Sherlock and Molly grabbed each other's hands and they walked over to the table where she had been sitting before.

"Molly..." Sherlock started. "Yes?"

"Would you like to have dinner at 221B on Friday?" He asked cautiously.

"I'd love to." She replied, kissing him on the cheek.
