You get back to the flat from a crime scene and plop down in Sherlock's chair very dramatic like.

"Well, that was dramatic." Your best friend, Sherlock says.

"Wonderful deduction Sherlock." You reply sarcastically. You then chuckle to yourself before saying "I can't believe that Lestrade actually thought that we're dating."

"Well we were flirting quite a bit today." You arch an eyebrow.

"Oh so you admit that we were flirting."

"While insulting each other." You laugh. Suddenly there is the sound of your brother's Tardis.

"Don't get in trouble while I'm gone." You tell your friend as you stand up. "Apparently my brother needs my help again." You then head to where the Tardis is and go inside.

"Hey Sis!" The doctor says as he puts his foot on the consul. You arch an eyebrow.

"Do you need any help there Doctor?" You ask. Your brother sighs as he takes his foot off the consul.

"That would be helpful." You laugh as you help him out. When the Tardis lands, your brother takes your hand with a grin. "Allons-y." He says.

-Time skip-

"It's all timey-wimey wibbly wobbly... stuff." Your brother says, making you start laughing hysterically. Your brother throws you a look. "Did I miss a funny thing or something?"

"Explain later." You reply. "Lets get out of here."

When you get back to 221b Baker Street the first words out of your mouth was "What trouble did you get into while I was gone?"

"I might've shot the wall." Sherlock replies sheepishly. You start laughing (again).

"Riddle me this." Sherlock says. "Why do you find this so funny?"

"My brother made me laugh hysterically, and well apparently I wasn't done laughing when I left the Tardis." You reply in between fits of laughter. Sherlock rolls his eyes... but soon he's laughing along with you.

"What the hell is so funny?" John asks walking in.

"I have no idea." Both you and Sherlock reply at the same time. John just rolls his eyes and walks out shaking his head.
