Hehe, I have great plans for that ring! But they are both married to their work, and Sherlock is also married to the Watsons, so... ;)

I actually think that the computer Mycroft brought wasn't his work computer. I'm pretty sure he would keep better track of something like that then having it at his mother's kitchen table. But it feels good that Sherlock would think about the same, doesn't it?

Thank you so much for taking the time to write such a lovely comment :)
