Perhaps there was another reason that Sherlock was so upset on the plane.
I’ve been thinking about the tarmac scene recently since I re-watched ASIB last night and I couldn’t help but get stuck on these two particular scenes:
Which made me think about this scene…
During the tarmac handshake scene, Sherlock takes off his glove to properly shake johns hand and to say goodbye to his best friend, but could it be something more?
After the first initial handshake, there is a rather large pause before one final shake and Sherlock walks away to board the plane.
Assuming that Sherlock did take his pulse during this scene, there is a chance Johns heart was beating faster than average. Sherlock, think he was going to certain death at this point, would be thinking that he had missed a very large opportunity with John.
No…He wasn’t just upset about leaving his best ‘friend’.
But what if the reason John started seeing Mary after her death is because he had already seen one of his important people dying and then coming back (Sherlock) so he just clutched on that hope that Mary wasn’t dead like Sherlock wasn’t.
Sherlock looking at John:
I am enamoured even by the way your fingers move, the way the light plays on your skin, with your hair and your smile and your laughter, with your voice, and how you get around things you love, with your humour,
