Episode 3: I skipped from 08:25 to 08:30 (on amazon prime). There was still a little bit visible on the floor but hard to tell. To be extra careful skip to 08:45 when the next scene begins.
Episode 4 is safe! Skip the recap though.
Episode 5: Charlie v* when he starts running apparently. Won't lie... I just skipped the whole scene which for me was like 13 mins to 16 mins.
Episode 6 and 7 are safe!
Episode 8 is safe! There is mention of feeling sick and someone says they are p*king in the bathroom but nothing can be seen or heard.
