Thomas is an Irish musician who plays the violin for the Dandelion Troupe. He's a quiet, talented individual with a strong dedication to music. While he rarely gets angry, one of his triggers is when someone insults his playing or his genius pianist friend John Whittard. Thomas gives Nadja her first dancing prop - a baton-like instrument with a castanet attached to one end and a bell on the other. In addition to being musically gifted, Thomas is practical and down-to-earth when it comes to everyday life. However, he can be cowardly in the face of violence or physical danger, prompting Abel and Sylvie to give him alcohol to overcome his fear.
