Glee: The Day That Everything Changed
When a gunshot is heard at McKinley, everyone is shaken to the core, and things will never be the same again for anyone, especially Kitty Wilde. My take in the season 4 episode Shooting Star. Like Passion Is Wonder-ful, this will eventually be expanded into a chapter of The Ballad of Kitty and Artie.
This is a single chapter story.
