Are there any recurring patterns (something of any kind which is repeated)?

I think there is the motif of dyfunctional relationships. There is a motif of dysfunctional relationships throughout the movie, both romantic and sexual, and also familial. The most obviously dysfunctional relationship is that of Charlie and his Aunt Helen, since she is abusing him. However, his sister is also in a physically abusive relationship which she makes Charlie promise to keep hidden from their parents.

Another dysfunctional relationship in the movie is that of father and son; Brad is gay, but frightened to admit it to his father. When his dad discovers the truth anyway he becomes physically abusive towards his son. He does not know how to love his son unconditionally and intends to shame or beat him into living a life that is a lie. Their relationship is basically dysfunctional because it will thrive whilst built on this lie, but will disintegrate quickly if Brad stays true to himself.
