Scared to Death
Thomas Rivers was first introduced when The Five discovered his body alongside Esther Collins in the basement of the old Savings & Loan building.
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.
