In which a main character is exposed to or infected with something very bad, usually potentially fatal and the exposure/infection is a main focus of the episode. In television, unless a character experiences a near-death revelation that completely changes them or dies, these episodes are typically not wham episodes
, but are still usually a big deal, often airing during sweeps.
The infection usually advances Character Development
by causing the character to rethink their life. In television, typically the person who is infected is involved in a relationship that seems likely to become romantic
, so you can usually expect a good moment
from that couple. In the best-case scenerio, this can result in a Love Epiphany
. If the infected party is not a member of the golden couple
, those two characters will also probably have a meaningful (and shippy) conversation about the fragility of life.
In television, this is most prevelant on crime and medical dramas, not surprisingly. The exposure/infection usually, but not always, happens to a leading character as opposed to a supporting character. A common exception occurs when a lead character's love interest is a supporting character.
There are also countless films based on this premise.
