A young (ten to fourteen year old) character has serious separation anxiety and/or abandonment issues. But it's never said if this is due to her parents.
There is a scene of characters chasing another character down stairs, who stumbles and falls slightly. The scene is framed as comedic and no one is injured.
Episode 4 has a scene that can be interpreted as rape. It has two people tied up and a girl with a bag. Episode 6 has a girl discover she was photographed undressing by her father. It will be a scene with a computer.
It's not exactly possession, but there is an episode focused on a character who has DID; it explores the lack of healthy communication between alters and how one alter's interests/job actively interfere and cause stress for another
On one hand, it shows a cop being corrupt in episode 4 and treats it negatively. On the other hand though, the episodes tend to follow two investigators who at one point get physical with a suspect whose a kid and treats it as normal. This is what I vaguely remember so feel free to correct me.
Episode 8 follows three people (including 1 child) who are trying to kill themselves. They go through multiple ways but always seem to fail. This episode might be quite triggering, but can be skipped, because characters and events don't come up later in the show.
Episode 1 shows a porn image, episode 3 and 4 involve a lot of sex with the 3rd one having audible moans, and episode 6 involves a girl who discovers she had been photographed undressing without consent.
