"…Igsitu da…" Red switches languages.
"…" The Ahdem and Havvah are not sure if they heard it right, and it takes them a second or two to process that the language only them in the world, speak, or even remember, is spoken to them by Red.
"… bwun…" Havvah nods, just to clarify.
"… ymbhat…" Red smiles.
"D-dyisutna?..." Ahdem and Havvah are wide-eyed.
"Fumio. Please, deactivate the thingy in your cave and give it to me." Red switches back to Japanese and asks Fumio.
"Y-yes boss." Fumio immediately follows orders, knowing that he cannot understand the language that Red and the couple are using anyway.
"Well, just like Rezonad…" Red switches languages again to continue the conversation.
