No worries. English version + Italian cut subtitled, two separate discs. Now it's clear.

Msycamore, I sent you back the file with some explanation attached.

Leo, please open the film in Italian and check at 56.25. The lines "Lo sai cosa sono questi? / Sono morti", can you tell me who the heck is speaking there? The first line is definitely delivered by THX because I can see his jaw moving. The second line "sono morti", is it still THX speaking (that's what I first thought) or is it the hologram replying? Thanks for your help. Msycamore was puzzled at that but so am I
