Ray’s commitment to being a dom means he never deigns to explain the situation to Colin, and the challenge of not only obeying the rules but deciphering them in the first place gives Colin the sense of purpose he’s been searching for. It’s a relationship that brings him to a place where he discovers what he wants as a sub — and that Ray might not be the person to give it to him.
Outside of the occasional admiration for how good Skarsgård looks in his riding outfit, there’s no othering gaze to sensationalize BDSM in Pillion. It’s simply a way of life here, one that gives Colin the opportunity to actualize his true self — and to experience the heartbreak that occurs when we need different things than the people we love.
