Single Tear

A Single Tear generally occurs when a Mary-Sue angsts. It is usually described with very urple prose, something along the lines of "a clear, glimmering drop of pure diamond". The Tear then tends to "glide down her perfect cheek".

Using a Single Tear is a legal charge, providing some relief for the Agents that have to suffer through witnessing one.

The Inheritance Cycle is especially guilty of this.
