Thoreau Lionett Jr.

 is a human child, the brother of Beauregard Lionett. As an NPC, is played by Matthew Mercer.

Appearance
Thoreau Junior, called "T.J." by Beau is a young boy of two-and-a-half in the spring of 836 PD, who in many ways looks like a young boyish Beauregard. He has longer hair that’s in a wild curl and looks like he just got out of a shower and had his head briskly dried.

Background
Thoreau Junior, or "T.J.", was born a few months after his older sister Beau was forcibly sent to the The Cobalt Soul in Zadash. When he was born, Beau received a letter from her mother telling her of his birth, which she interpreted as saying, "Don't come home. You've been replaced with a better model." Beau had no interest in meeting him until Fjord suggested that he was innocent of any mistakes her parents might have made, and he was part of her blood.
