Sherlock looked at his Serena. "I think we are very overdue for a sleepover my dear. What do you think?"
Serena looked up at him and grinned. "I was just thinking the same. Do you have the floor this time, or is it my turn for it?"
John groaned. "Is this some code for saying you two are going to shag? Because if it is, I'm going to Harry's."
Serena laughed and said, "No, John. We aren't going to shag. When I had a nightmare as a kid, I would go over to Sherlock's house and we would have a sleepover. We would take turns sleeping on the floor and on the bed, and we would drink hot cocoa and be normal. Well, as normal as we could be."
Sherlock smiled and said, "The last time we had one of those was when we were in high school. Mother put a stop to us having sleepovers in my room once we started dating, but we would sleep in the living room instead." He grabbed Serena's hand. "Will you make the hot cocoa, or shall I?"
"You know how to make hot cocoa? You? The man who doesn't know that the earth goes around the sun? When did you learn how to make hot cocoa?" John was shocked.
Sherlock snickered. "Yes John. I know how to make hot cocoa. I'm not completely worthless in that regard. At least I don't think I am. Serena, am I completely useless when it comes to cooking and cleaning and such?"
Serena smirked. "Definitely. But I'm fine with that."
Sherlock gave a mock sigh of desperation and looked at Serena, a wicked gleam in his eye. "You're driving me mad woman. What can I do to stop it?"
"I can think of a few things." Serena winked and John groaned.
"That's it I'm definitely on my way to Harry's."
"Good night John! We'll see you tomorrow!" Serena waved goodbye at him and blew a kiss in his direction. There was that pang of jealousy again. Sherlock wanted all of Serena's air kisses. This was a stupid thing to be feeling, but here he was feeling it.
Serena sauntered over to him. "Let's have a sleepover."
