Sherlock was finally home after his three year absence. Now there were two issues that were pressing, the impending terrorist attack and John Watson. To be perfectly honest, Mycroft worried more about the latter than the former. Sherlock was so exited to se him again that it had been difficult to get him to say in hospital long enough to stich up his back. He seemed to forget that John was still grieving. Sherlock wouldn't want to talk of anything for Mycroft until he met John. But there was a danger baby brother did not foresee, so duty called the elder.
"You know, it is just possible that you won't be welcome."
The split second of earth shattering doubt was almost physically painful to Mycroft.
Do you really think so Myc?
It is a possibility that we must consider.
What do you think will happen?
The balance of probability states that he will at least a little angry. Be careful Lock.
I will.
"No it isn't."
As Sherlock left, Mycroft tried to believe that everything would be fine. He wished John would be too happy to be mad. He knew he was right, but he wished he was wrong.
