Midori no chikyû wa makasetoke - S1-E2
Audio problem: In the hangar scene at the beginning, Goat is talking to Akito. Seiya Uribatake in the background is arguing with his fellow mechanical worker about the reparations to the Aestivalis. The conversation happens in the back of the hangar and it is meant to be strong background noise, annoying enough to prompt Goat's reaction, but in the English dub it is so strong that quite literally most of the main dialogue is nearly inaudible because of it. The dubber also adds a surprised/scared "waah" at the end when Goat cuts him off, but that is incredibly delayed compared to the reaction of the character on screen. (00:02:35)
