A/N: After writing 'Love Is Red, Heartache Is Blue' this little idea wouldn't leave me alone - namely that Sherlock and Molly would realise they'd swapped coffee orders (see Chapter 2) and Sherlock daydreaming about Molly. Anyways, hope you enjoy! x

Disclaimer: I own nothing.

Stuck On You

Molly was cooking again.

He smiled as the smell of the biscuits she was baking drifted to where he was lying on the couch.

His smile widened as he realised she was making her famous brown sugar, macadamia and white chocolate cookies; his favourite.

"What are you smiling about?"

Sherlock's eyes snapped open and he looked over at John in surprise; the smells and sounds of Molly baking disappearing.

"Nothing, just thinking about the case," he said dismissively, sitting up.

"O-k," John said slowly, disbelief written all over his face.

"I think we need to go to St Bart's," he said decisively, stepping over the coffee table to get passed John.

"What? Why?" John demanded, scrambling out of his seat and grabbing his jacket to follow Sherlock.

"An experiment, it will clear my head," Sherlock replied, signalling for a cab.

"I thought you had a break through?"

"Whatever gave you that idea?" Sherlock asked, opening the door and getting inside the cab.

John mimed strangling him before getting in after him.

"So, you're not going to tell me what this is all about?" John clarified breaking the silence.

"Nothing to tell," Sherlock replied in a bored tone, looking out the window and absently tapping out a tune on the armrest of the door.

"You've been acting strangely ever since you got back," John glanced at him, "well, strange for you," he amended.

Sherlock chose to ignore his comment and continued absently tapping on the armrest, he stopped when he realised the tune he was tapping was 'Stuck On You.'

He needed to see Molly.

It had been easy to dismiss the discovery that she had invaded his Mind Palace when he was 'dead,' but it was almost impossible now that he was back.

He knew that he had to face the discovery sooner or later, but the dreams – dreams that were becoming increasingly domestic and…fluffy – were forcing his hand before he was ready.

Something had to be done.

He spent the rest of the drive puzzling over what he was going to say when he saw her, imaging different scenarios and trying to decide on the outcome he wanted.

They reached St Bart's faster than he was anticipating, which was the only explanation he could come up with for the way his mind went blank as they turned the corner and came face to face with Molly.

She smiled up at him and he realised it was all very simple really: he just wanted her.
