A tertiary character is a character whose purpose and significance are little. Throughout the game, Josh would encounter several of them moments before they meet their gruesome demise.
Train passenger
This unnamed passenger was encountered by Josh when he tried to find Kate on the other side of the cart. The cart's passengers had just been slaughtered by Ernst under the orders of his master Viktor. This passenger was the last one alive as he made it to the door just as Josh was about to open it, only to be dismembered by Ernst's harpoon.
