However, in s5e9, the suspect tries to kill a horse and goes as far as pulling out a gun and pointing it at the horse, complete with a fake-out gunshot that comes from a different source and hits someone other than the horse - but for a second it makes you think the horse was shot.
Minor characters are murdered, major characters are injured. All of this comes with blood. It’s not as brutal as some other shows I’ve seen, and there’s not exactly gore, but they certainly are not shy with blood.
To an extent. Not necessarily in terms of physical disabilities (at least I don’t think so; there may be something in the ten seasons that I’ve missed). However, mentally disabled people and people with mental illnesses aren’t always referred to in the best terms in this show, though I have certainly seen worse. A main character routinely calls his friend “crazy” or a “nutjob” for reckless and/or violent behavior.
A major character is claustrophobic. I don’t remember the specific episodes, but there is one in which the characters are entering a small tunnel and he begins to panic, and then another where a building collapses with major characters inside and he panics.
s5e9, a victim is poisoned with liquid nicotine and seen seizing on the way to the hospital. I’m pretty sure there’s a few other episodes in which someone has a seizure, too.
s5e9; it’s not the most overt spoiling of Santa, but its mentioned that a character’s daughter has stopped believing in Santa, and there’s discussion of how the character had dressed up and went to a great extent to pretend to be Santa. Also, in like every single Christmas episode this character pretends to be Santa for his daughter or his son.
A major character’s father is murdered at the start of the series; in fact, it is the catalyst for the first major plotline of the series and many of the events of the series happening. Later on, a major character’s mother also dies.
