In Twin Peaks, season 1, pilot episode. Leland Palmer is called away from a presentation to a phone call from his wife when they learn their daughter is dead.
Shortly before he is called away, a group of old people are given a presentation, the main speaker speaks English and a translator translates it to a German-ish language.
Twin Peaks, a fictional town, is located in the state of Washington, which is on the border with Canada. I am wondering what language they speak and why?
