Father Gabriel has previously shown his darker side, but this time it appeared to come out of the blue.
Speaking to Entertainment Weekly, the star said having sized Mays up, he saw him as “more of a threat than someone who can be trusted”.
He did not want to introduce Mays to their secure community where vulnerable people could be exposed.
Gabriel, Aaron and Mays ended up playing a game of Russian Roulette, which made Gabriel question the new character’s motives.
The star added: “I think that just kind of capped it for him, that someone would do that to other people, put other people in that position, is beyond hope.”
