I was watching JoJo`s Bizarre Adventure and during Polnareff's speech to J.Giel(link here: https://youtu.be/y-Ov19GvGo0?t=22s) he says 22 seconds in: この場合そうゆう and then he says what i hear as: "せるふゆうんじゃね" but i looked せるふ up and it's only definition is self, so i was wondering is that what he really said or am i hearing it incorrectly?
Thanks in advance!
