It is impossible in any aircraft, regardless of type, for all crew members to know at all times everything which is going on. There will inevitably be some occasions when the pilot is unable to communicate to those not on the flight deck due to work level - whether physical or mental.
I am not an 'ex-shiny' bod; far from it. And I do accept that you lot in the muddy world do more than make the tea. But there is no need to assume that only your closed little world has any inkling of your activities.
Anway, enough of this. No-one still alive knows exactly what happened, beyond any reasonable doubt whatsoever. And that is the end of it.
