There is absolutley no need to translate this. It has nothing to do with the accident and the information value of the discussion is zero. They are just casually talking. Which is not uncommon during a flight of 12 hrs or more. What professionalism? Do you expect a crew to sit on their mouth for all this time? Obviously you have never visited a cockpit on a long haul flight.
I agree that the hand over briefing is somewhat minimal but in reality you don't need to talk a lot (except a CRM question: "Did you sleep?" - "mediocrly" he replies, which means not really). Specially if it is the captain who has to be briefed, and nothing has happened, there isn't anything to be briefed except "everything is normal". You see with one glance the point you are flying to, the state of the Satcom and of course also the technical condition of the aircraft.
This is again a useless discussion to find answer in areas where they aren't, for the reason that they don't understand the real ones.
