Thomas Rivers was an ancestor of Caleb Rivers and the original Caleb's father. Thomas was one of the townsmen who supported and later signed the pact. He was portrayed by Lyle Brocato.
Thomas is seen again in a flashback scene in 1917, where he is seen disagreeing with Esther Collins about signing the pact. He wanted to sign the pact to save any residents who went to war, in exchange for the deaths of five random teens, which he thought balanced each other out. However, Esther disagreed. Later, he signed the pact alongside a few other townsmen.
