HOW could THIS happen…let’s rewind..you, Sherlock, and John along with Mary had went on a small trip to Las Vegas for a small vacation and you all went to a bar after being leaving your things in your hotel, well with bars it’s undoubtedly that one or more of you will get drunk..well you and Sherlock got very very drunk..

here you both are now, naked in bed together your lipstick smeared on his mouth and other places and you with hickeys and what not. But now you both had rings on your fingers

Sherlock,”…We didn’t …how could I be so bloody careless ..” he grumbled laying back ..no doubt both of you feeling awful headaches from alcohol but also now feeling worse seeing the rings and eachother in the same bed.
