I'm writing a lesbian movie where a young women (23) is planning on coming out to her family with the help of her partner (25). The antagonist of the story is the young women Aspie young brother (19). He finds them in bed together. He doesn't want her to come out because it might break up their family since their family is religious. To me this makes a weak antagonist. I drawing a blank on how to beef up the character. The brother is high functioning and he knows what sex is and everything he just sucks with communication and social skills (like making off color joke, etc.).
