The day that John returned to Hell, Sherlock spent the rest of that day in John's bed, taking him in every way that he could, showing him physically how much that he had missed man. He wasn't able to say what he wanted to in words, he showed in with his body- enough that it even left a demi god walking funny for a few days afterwards.

Sherlock watched over the next month as the war flared ever harder, then, as quickly as it had started, one side let loose a couple of bombs, and it was over.

Sherlock was already a third of the way through his time with John, but this meant that barring another war, he would have at least a little time with John before he went to Melbourne, his Southern Hemisphere base of operations. It was ideal because they spoke English, and since John had been English, and Austrailia had been an English colony (albeit hundreds of years before) it wasn't that different than London, his Northern Hemisphere base of operations.

"When you go back to Australia, I will set up my company in the Overworld, back in London. We can communicate with phones or those computer things. I know there s a time difference, but I don't need to sleep, so late night isn't a problem for me."
