Expressions convey what a person feels, so — logically — if a character has an expression permanently glued to their face, they must be feelin' it all the time. A Perpetual Expression, then, is a characterization device used to cue the audience of someone's nature. Very rarely do others remark upon their apparent facial paralysis, even if one's visage is stuck with a rather unsettling look.
As a side effect, when the character's expression does change, it is always important, and marks a big change to the character's normal demeanor.
Most common Perpetual Expressions include:
- Eyes Always Shut
- Perpetual Frowner
- Perpetual Smiler
- Dull Surprise
Note that the accompanied characterization of these tropes should be left in their own article; this is merely an index for the varieties that are frequently ever-present on someone's face. Note however that many Perpetual Expressions mix and match various Smile Tropes and Eye Tropes.
