Hello, is there a good soul familiar with the lingo used in the series that would be willing to help me clarify lots of terms in this episode please? I have to translate subtitles for this s06/ep22 but lots of the lingo is unknown to me... I usually try to research everything online but not always successful with some terms and then I need to take a blind guess, but thought if I reached out to native speaker who knows the exact meaning of some phrase/word, I`d be really lucky...
