Coming Home - S1-E13
Plot hole: The logistics of the episode don't really make sense; Amuro's home village is held by (literally) a handful of Earth soldiers cut from their main force and that spend their time getting drunk and acting as occupation force, but Zeon has a full base (again, literally, almost) next door that sends reconnaissance troops and even aircraft to check for any activity at the refugee camp. There's no reason why the undisciplined and free soldiers would stay in such a dangerous position where they could be wiped out by overwhelming forces anytime, nor why Zeon would keep a pocket of the enemy forces that they can crush with ridiculous ease.
