This is only part 1, but he clearly spells out that Zelensky is an agent of MI6.
I haven’t watched it yet but Patrick Henningsen suggested that Elensky’s family had been kept in a gilded prison on at least one occasion to ensure that the marionette followed the choreography correctly. I can’t pretend I felt sorry for him but I did get somewhere close to it. (As if Elena Zelenskaya would be loyal to anyone other than herself lol. She’s a screenwriter by profession, and he an actor, it’s not exactly subtle.)
