Should I have posted this somewhere else on the forum? But it's so TAB-related. And, I realize that Jim possibly being alive is an irritating topic, but tell me where I'm wrong if you have the patience.
... because, for example, of this line: "Of course he’s dead. He blew his own brains out. No-one survives that. I just went to the trouble of an overdose to prove it." (in response to MARY'S "So he's dead".
Of course they can all hear him. But the whole line is a lie for Mary's benefit, because he DIDN'T just overdose IN ORDER TO prove it, he got high before he knew England was hacked (I believe Mycroft about it), either to end it all (scary), or to make it easier (slightly less scary but still terrifying).
(Sorry for the shouting, but bold is almost indistinguishable from normal here).
Also, the blood flowing from under Jim's head in TRF is scant when you compare it with the spectacular hole in the back of Moriarty's (and Emelia's) head in TAB, which are supposed to look realistic; also, the frantic dig at the cemetery (which was a mind palace scene after all) and the mind palace Holmes saying that Moriarty's "body was never recovered" AND Anderson's theory about the latex mask in TEH (whih means that Anderson at least knows nothing of a corpse on the roof, and probably Lestrade doesn't either) all seem to mean that Sherlock doesnt know EITHER where Jim's body might be; also a theory about a second shot fired simultaneously (in this case, by a sniper from another roof, perhaps through a blood bag attached to Jim's back) has been around for years as an explanation for TRF (on The Final Problem I think). Also, Moffat said that TAB should settle all doubts about Jim possibly being alive, and I don't trust the man.
