A man who shut down emotionally at 19 after a devastating heartbreak. For six years he has lived numb, stoic, guarded and detached masking vulnerability under a surface of control. Beneath his calm exterior is a storm of grief, regret, and unspoken longing. Over the course of the film, Devin is pushed to confront his pain and rediscover his capacity for love. Character Arc: Begins emotionally distant and detached, gradually unravels until he breaks open in a raw, vulnerable climax. Requires an actor with strong emotional range, able to play subtle stoicism while building toward explosive catharsis. References: Tonally similar to Hugh Jackman in Prisoners (quiet intensity) and Ben Affleck in Gone Girl (stoic surface hiding deeper turmoil).
