A high school reunion murder

A killer with diplomatic immunity that still gets arrested through some outrageous loophole

There's always an episode where a psychic comes forward to help. Everyone will be extremely wary of the psychic except for one person. And the psychic will end up being correct.

Murderous twins. They're often separated at birth. All the investigators will make a joke about it being twins and then are SHOCKED when it actually does turn out to be twins.

Killer child. Literally just a little kid that kills (usually another little kid)

An episode that villianizes people with DID. (sometimes the writers do a 2 for 1 special and make one of the "alters" a different gender so that they can both villianize mentally ill people, AND make transphobic jokes 🙃)

Sleepwalking murderer

Murder by proxy via hypnosis. Similar to the psychic, most of the team will be very skeptical.

Someone finds a body in a time capsule

Some killer that just got like WAY too into Dantes Inferno

Murder victim that has multiple families/wives

Murder at a roller derby. This episode will usually give off big sapphic vibes

high school reunion: 5x17 / death of the queen bee (brennan's hs reunion. i hate all her fuckass classmates)

diplomatic immunity: 2x06 / the girl in suite 2103

psychic who helps: 5x01 / the harbingers in the fountain (angela's psychic avalon... her twin sister ended up being one of the victims. top tier episode and season opener imo)

murderous twins: N/A but there is an episode centred around twins (8x03 / the gunk in the garage)

killer child: 2x07 / the girl with the curl comes to mind (the victim was also a child and it was accidental), along with 9x03 / the butcher in the car (in this the victim abused the kid's mom and was an adult)

an ep that makes fun of DID: N/A. 12x01 mentions a killer probably has DID but i don't think they're making fun of it as much as making an obeservation...?

murder by proxy via hypnosis:... N/A. i THINK... we've got one (or a few) case(s) of people claiming to be possessed so that's probably close enough (2x10 / the headless witch in the woods)

sleep walking murderer: N/A

time capsule murder: 3x07 / the boy in the time capsule. self explanatory title

some killer that just got like WAY too into Dantes Inferno: if we're talking about the video game aspect... 5x09 / the gamer in the grease and like, 10x04 / the geek in the guck ig? but i'm kind of grasping at straws

victim with multiple lives: 2x05 / the truth in the lye: the guy had 2 wives, 1 kid with each of them and then has to gall to cheat with and impregnate the receptionist at his work :/
