"It is really questionable whether The Assassin needed to come back for a second series."
watch all six episodes of season 2 then do a Search for:
the assassin season 2 ending review
and you will get lots of break down / recaps, explanations, ideas, interpretations and theories
I think that by the time they broadcast season 427 we will have no idea about anything at all
¯\_(ツ)_/¯
