The only character in this Casting Call that is unaligned against either Cain or Iris, Reilly is a Hunter attempting to find a cure for his dying Ghost. This quest has made him rather bitter and resentful of his Ghost's efforts to provide emotional support, but it has also given him a grim, unending resolve to find a way to save his Ghost. He encounters Cain by chance and is then sought out by Roderick and Foxtrot, who offer their help. Reilly usually speaks with an emotionally-charged, determined baritone.

Reilly will return for Season 4 of Infinity, so his voice actor will need to be committed to that season as well.
