Something Big About Mycroft
Those who have discussed with show with me will know that the whole Mycroft-Moriarty connection never sat well with me. Having him imprisoned and letting him go only to destroy Sherlock’s life - not really. (Plus - if we include TFP - he had allowed his sister unsupervised contact with this madman.) But this is what they made us believe, right? And then I realised something. Look at this dialogue from TRF:
MYCROFT: But James Moriarty … the most dangerous criminal mind the world has ever seen, and in his pocket the ultimate weapon: a keycode. A few lines of computer code that could unlock any door.
JOHN: And you abducted him to try and find the keycode?
MYCROFT: Interrogated him for weeks.
This fascinating screenshot from TRF shows that the imprisonment we see in THoB and which is referred to in TRF is indeed the same:
The arrangement is quite similar but in TRF we do get one, but two Mycrofts which may be taken as a hint that he is playing a double game. The technique of superimposing or mirroring characters is used very often in the show but I cannot remember this constellation. This is the only time one character is not mirrored but shown in two different situations while being paired with a second character. To me this means that THoB Mycroft is different from TRF Mycroft, that he is not what is appeared to be in the earlier episode. And there is more.
