Oh, yes, I do not share every opinion on there but some of the metas are amazing and very convincing.

For you, Solar.

I find this cene to be slightly sad and nostalgic.
Sherlock already knows that his dealings with Moriarty will hurt John in a near future....
 

It's a perfect shot and the word 'nostalgic' absolutely nails it. The mirror, the lamp, the lighting, the atmosphere - and those two men, preparing for Moriarty, probably both knowing that this might be the last time that they're together in 221B like this...

And there is the very short moment in the hallway. "Ready?" "Yes." So full of meaning. Always takes my breath. 

Girls, please stop it.

But it's so true, nakahara... everything that happens in TRF after that is breathless, unstable, uncertain and so different from the other episodes. They are basically on the run, even if they are not literally running all the time. Sherlock and John as we knew them are no more.

Yes, it was this hardship that made them realise what they mean for each other, how closely they are bound together.

That is the price they both pay. This is the true burning out the heart.

Of course. And I do not resent his being together with Mary. But in the light of series 3 Moriarty's threat gets a new dimension. 

Still, I find it symphatetic that even being with Mary, John never forgot about Sherlock.
