Gannicus (pronunciation)
It sounded like "Gattacus" until I saw that the spelling was "Gannicus."
This is why subtitles or captions are always needed if you want to understand all the dialog.
The positioning of the tongue in the pronunciation of "n" and "t" in English occurs at a very close spot behind the teeth. When emphatic expulsion is needed as for actors in a noisy environment like those of this story their pronunciation might alter the cause of the sounds making thus the "n" to sound more like the "t."
I'd be interested to learn if anyone else heard "Gattacus" instead of "Gannicus" during this show.
