Sherlock and Joan have been in a relationship for about a month and things seem to be going great so far...

Joan woke up and went downstairs, still in her nightwear, to find the kitchen was still a mess from last night.

'Sherlock!.'
She heard him tumble out of bed. He came downstairs to the kitchen.
'Didn't i ask you to clean this up last night?.'
'I was going to clean it up this morning when you were still in bed so it would be a nice surprise. I didn't anticipate you being up this early.' He gave her his puppy dog eyes.
'No, don't do that.'
'Do what?.' He moved closer and wrapped his arms around her waist.
'Your puppy eyes! You know i can't resist them.'
'Really?(!) I didn't know that.
'You are so annoying.' They both laughed as Sherlock leaned in and kissed her. Joan wrapped her arms around his neck and pulled him closer.After a moment, Joan pulled away gently. ' I have to go get dressed.' She tried to move but Sherlock wouldn't let go. 'Sherlock.' He chuckled as he watched her go upstairs. Suddenly the door bell rang.
'Watson! Are you expecting someone?.' He opened the door to find a tall, slim, dark haired woman standing before him.
'Irene?'
'You miss me?.'
