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
I really love the fact that this show is called NCIS: Tony & Ziva because I think back to all of the times we were told “this isn’t the Tony and Ziva show”
