Yvonne Reynolds is Neal's younger sister.
Yvonne is fifteen year old high school student attending Sanctuary Cove High School alongside her older brother. She is a straight-A student and one of the most popular girls in school. Because Neal is being constantly being bullied by Callen and his crew, she worries about her brother.
Yvonne is generally kind, accepting, and down-to-earth. She's commonly known as the good girl, and sometimes even a nerd. She's willing to show her rebellious side but is proud of who she is.
