OK BUT I JUST REALIZED SOMETHINH AND I DONT KNOW IF SOMEONE ELSE HAS POINTED IT OUT YET BUT...I'LL SAY IT ANYWAY. John's hands. One on Sherlock's nek and the other on Sherlock's arm. Doesn't it remind u something? It's exactly the same way Sherlock hugged John in TLD. Coincidence? Nope. In this show coincidences don't exist. It means, if you think about it, that Sherlock not only remember how John hugged him, but also that Sherlock thinks that it is the way John want to be hugged, I think. It is the way John makes feel someone loved and safe and it is probably the way Sherlock felt and so Sherlock did the same when John needed, he hugged him with one hand on John's nek and the other on John's arm. Bacause in that moment John needed love and to feel safe. I...I don't know if it makes sense but this hug, John's hug, hit me and reminded me of Sherlock's hug. I don't know what to think now, I need a blanket. Also, I feel really stupid cause probably someone just noticed it ages ago soooooooo now it's time for me to go. And hide. Bye.
