Katelyn O'Brian

Katelyn O'Brian was a child who lived in Charleston at some point after the Great War.

Background
Katelyn's mother had died and her father told her that she had gone to heaven. When her father was attacked by "big bugs," the Responders saved his life. To thank the people who saved her father, Katelyn wrote a letter to Maria Chavez, expressing that she wanted to join the Responders when she was older.

However, the note Together soon, written by Katelyn's father, indicates that the O'Brian family met a much darker fate. He states that he would join her and mommy soon and calls Katelyn an "angel," indicating that Katelyn died as well and her father committed suicide to be with the family in the afterlife.

Appearances
Katelyn O'Brian is mentioned only in Fallout 76 unused content.
