Unsatisfactory season finale approaching -- please step back from the platform edge
Where was I?
Obvious (to me at least) in the season opener that Missy was The Master, and that what appeared to be the afterlife wasn't. The first person to show up was the chief rubbish robot; robots don't have souls and either don't have an afterlife, or have a different afterlife to living things. [Mmm. We may yet get to discover in what sort of afterlife, if any, Time Lords believe.]
And the swearing thing with the psychic paper. That smacks to me of a hasty script rewrite, of a scene originally between Seb and The Doctor (Addison/Capaldi; Ollie/Malcolm Tucker), and that line was too good to lose.
To get collected by Missy ... well, humans from Robot Of Sherwood don't show up, nor from Flatline, but humans from Into The Dalek do, as does that copper in The Caretaker that we see get blown to carbonised bits by the Skovox Blitzer. Missy is collecting people an instant before they are to be killed, and killed in ways that either destroy or mangle a body in such a way that anybody finding the body, if there is one, will not bother looking at it too closely and then discover it's a replica. A replica which has probably arrived via the same transmat beam that Missy is using to kidnap people.
Danny Pink doesn't quite count. But 'PE' is connected to Clara, whom Missy is exploiting to get to The Doctor. I think we're going to find that Danny Pink is alive and well.
Why did the writers go for the cliché of having Danny kill a child, and not something more nuanced and subtle? I think, precisely because it was unsubtle -- "let's throw in this idea that carries the smallest possible requirements for exposition ***splat***, now, get on with the story". I was expecting Danny Pink to be doing the same job as Jack Harkness in Series 1; the writers then put somebody in position in the Tardis to be a soldier in the series finale, able to run around killing things in a way that The Doctor was not. We might be seeing that again now.
What's with the Matrix Data Slice then? Missy is doing The Matrix with the kidnapped, scanning their memories to inform a holographic environment so that she can manipulate them. The reason why the child that Danny shot doesn't speak could be that Danny never heard him speak, so there's no data from which to synthesise a voice for the hologram of the child.
Or, bearing in mind that Who can be excessively sentimental, it's perhaps more likely that the child isn't dead, and Danny Pink is going to be able to return him alive to the wider world, and free himself from his sense of guilt.
Sooooo why did Missy collect the chief rubbish robot then in Deep Breath? Not a candidate for Cyberconversion. What would a Rubbish Robot make of a Cyberman, or a Cyberman make of a Rubbish Robot?
