For a while they just sort of...looked at each other. Sherlock searched his mind for something appropriate, quickly discarding several sarcastic possibilities. John was clearly in shock...in fact he looked quite ill...
It seemed as though an eternity had passed although in reality Sherlock knew it was only a matter of seconds but finally he found the words he knew he had to say to John and he just hoped....hoped so much...that they would make everything just go back to normal...go back to how things were...he'd said the words before but never meant them...now he did, now he really felt he did...
"I'm...sorry."
