There is a character who's pretending to be Native American, and among other things wears a very culturally insensitive headpiece. The main character keeps saying that he's being an asshole.
Technically Cecil telling everyone about him going on a date with Carlos could count as outing since he probably didn't ask for his permission, but it's never really mentioned.
(Spoilers, obviously) Both Old Woman Josie and the violet head of Hiram McDaniels die in late season five, and in season eleven Sarah Sultan, Station Management, and the Glow Cloud die, though only the Glow Cloud's death is permanent.
Especially early on there's a lot of government gaslighting double think stuff going on. Its generally over the top and obvious to the audience but it is there
Not so much child abuse as there is like really, really bad parenting. Cecil's mother abandons him and his sister when they are very young, forcing Cecil's sister, Abby, to have to raise him.
There are multiple dead animals including a dinosaur coming trough a rift and dying, a giant centipede dies in the book it devours, the glow cloud drops dead animals and there is a mention of a dead animal fire implying there are many off screen animal deaths, one head of a five headed dragon is shot and killed, each head has its own personality and will and although the other 4 heads continue to live this head dies
In the episode 'glow cloud' the glow cloud drops dead animals on the town, there is also a mention of a dead animal fire implying there are enough dead animals in constant supply for an ongoing fire to be necessary
Off the top of my head, Cecil is restrained twice, both for reasons to do with possession. In 70B Review, he's handcuffed by a friend so his body can't be puppetted against his will to protect her, and in 166 Delta he has his husband cuff him so he can't be mind controlled into doing evil, and also it's implied the couple already had the handcuffs for sexual bondage reasons.
In episode 120, several characters carve smiles into their own faces with glass. It is described by other characters telling a story, and is done so in a mildly graphic fashion. There are no gruesome sound effects to accompany it.
A character dies who was viewed as a parent by other characters. There is a whole episode about her funeral and how her death affected the other people in the town.
a few instances, but the most recent one is a woman in the town who is investigating everything and kidnaps a character who is a first sized river rock and basically kills her because she didn’t believe that she was sentient
I don't remember what happens in the other instances (there aren't too many), but in episode 33, for under ten seconds, you can hear what sounds like someone choking.
The strex residents often carve smiles onto their faces. In the episode “All Smiles Eve†the central characters are described cutting their mouths into smiles
Nightvale is a very unhinged place and there are a lot of very concerning things going on, such ss time not working, buildings nit existing despite the fact that you can see them, and general spooky things.
In the books we discover Carlos was in the desert otherworld for 10 years whereas for us and the citizens of nightvale it is 1 year, the podcast vaguely touches on this and in the books it is clear he is traumatised Cecil also hears himself die once and sees himself die once, he also hears cassettes of memories he doesn't have, this clearly unnerves him
In one episode Megan wallabys birth is mentioned, she is however a severed man's arm and not a typical baby, she is not mentioned again until she is in school
No slurs and practically no homophobia. In the episode Cal, it is mentioned that Cecil's brother from another universe might be homophobic, and Cecil doesn't tell him he's gay for fear of how he'd react.
There are satirical references to the anti-semetic “lizard people” theory, but one of the writers is Jewish and so is the main character so there’s definitely not any actual anti-semitism in it
I think Cecil occasionally mentions wearing more feminine clothes, but the joke isn't that they're made for women, it's that the clothes are incredibly ugly.
If you wanna be technical about it, there is a character in episodes 1-25 who, despite not being native, claims to be as such. Everybody around him derides him appropriately, and he's generally unliked by other townsfolk
A little bit in the first few episodes/seasons. Cecil comes on to carlos very strongly while talking about him on the radio. Carlos later expresses his discomfort about it and cecil stops
There are many, many mentions of blood. This is especially true in episodes 19, 46-49, 70, 73, and 120. Most Desert Bluffs characters are described as having blood somewhere in their appearance, with the most heavily featured of them having an intense fascination with blood.
