FBI Special Agent Olivia Dunham, brilliant but formerly institutionalized scientist Walter Bishop and his scheming, reluctant son Peter uncover a deadly mystery involving a series of unbelievable events and realize they may be a part of a larger, more disturbing pattern that blurs the line between science fiction and technology.
This tv show contains 86 potentially triggering events.
In episode 115 a woman who is walking her dog is abducted and killed. Her dog isn’t physically hurt, but it’s later stated that he was tied up to the fence outside her house, whimpering. In episode 118 they raid a scientists house where a dog is in a cage and it is evidence that he has been tested on. The scientist is also seen drilling open a dead animal which may or may not be a dog. In episode 214 a nazi kills a dogs human. The dog is physically unharmed but cries over his dead human’s body.
Animals are used continuously in experiments. In episode 116 animal rights activists break into a lab and we see many animals apparently distressed and in cages. Olivia later goes to an animal testing lab. The conversation is rough because it talks a lot about animal testing. We see animals in cages though don’t see any abused on screen. In episode 118 a dog is in a cage having been tested on, and Walter infects a rat with syphilis and tests a potential cure on her. The rat squeals and struggles. It doesn’t work, and the rat dies. In episode 202 Walter uses a frog in an experiment.
Olivia is experimented on without her consent, for instance by being left alone without any explanation and confronted with the seemingly dead body of her friend.
A shot in season 3 episode 9 “marionette” a man has his eyes removed.
Season 4 episode 3 “alone in the world” a man attempts to give himself a lobotomy, stabbing through the orbital socket — the eye itself is not harmed but it is an unsettling visual
twin towers are both seen standing unharmed in the alternate universe, there is references to this but no actual depictions as far as I'm aware (although there are episodes where plane flights go awry so be careful if that's triggering)
Several old books of German literature with annotations by Walter's father, Dr. Robert Bishop (who worked as an antifascist spy for the Allies during WWII), containing scientific notes, were sold by Peter and used for a paper collage portraying Adolf Hitler.
Walter Bishop returns to the mental institution he was released from in order to gain plot-relevant knowledge. In order to do that, he pressures a former fellow inmate, leading to a scuffle between them and Walter getting sedated, as well as being (temporarily) re-institutionalized.
Walter suffers from one after having to sleep in a different apartment for the first time in several years.
Cameron does, as well, as a result from being experimented on as a child.
Character named Hughes who is being held suspect creates a noose out of wire and hangs himself. You see him pulling apart the wire with his teeth (which causes his teeth to bleed) and making the noose, and then you see his body hanging for a few seconds. Timestamp 25:53 is when we start to see him making the noose, Hanging body is shown at 27:15. Entire scene is over at 27:20. Body is shown again and closer at 27:40 as it discovered, second scene is over at 28:01. So skip 25:53-28:01 for these scenes. They are interspersed between the scene of Olivia and Peter exhuming the body of Hughes' wife and child, they find out the body of the child is missing and it looks like something dug it's way out of the coffin.
Chinese people are misrepresented imho, also the plotline seems very white savior-ish (disclaimer: i am a white person, so take that with a grain of salt)
