Working backwards from what's be said so far Thursday isn't mentioned in Morse and the explanation in the fan documentary (shown after the news) is that the combination of Thursday being guilty of a crime and Sam not being identified because he is now a target of the bikers, means Endeavour as Morse must never refer to them. A bit implausible but they admitted Thursday was never mentioned in Morse so put this as the reason why.
Bright is sitting by his wife's grave. Some of the most touching scenes were Anton Lesser as Bright having to face his wife's illness and eventual death. Its funny in the fan documentary Lesser comes over (another great acting part) as being a bit giddy and light hearted, but more often than note plays parts where he has to convey horror and desperation. (Though always enjoyed the Roman detective series he did for the radio which was not like that at all.)
Still think the Joan plot line didn't really work. As Endeavour clearly was able to be quite open and frank with women, and all this nonsense of endlessly referring to her as Miss Thursday was just silly.
I think this is the only episode when on two occassions that had characters repeat the thinking behind how a crime had been worked out. Maybe it because they know that we arent always as clever as Morse, and normally in a follow up episode things are explained. But it sounded a bit odd. Sort well this happened because, and then another character says, oh you mean this happened because ...
But again as said in the fan documentary having the same writer made huge difference to the script and having bits of the past come up in later episodes.
Certainly towards the end of Lewis some of the scripts were terrible.
However, still dont think that even with 10-15 years or however long it is meant to be, the Endeavour character would become the boorish bully that Morse was.
Do you think in fact that the outcry will be so great we will have Morse the Carshalton years, with a totally different actor?
Maybe Netflix will go rogue and cobble one together - and it will be pants.
