Although I saw that someone in the feed had already translated them, too late, who cares, still -
The translation of the prison slang that Igor speaks when he starts giving the interview to Yulia was challenging, I used roadman slang as a basis, and in the end I put all the slang I could find into it. So if anyone knows English street slang and can offer their edits - go ahead, I'll be only too happy to educate myself.
