Hum... it's not about a step toward coming out, though. Jason has more (and maybe bigger) problems than coming out. He's trapped down in other people's expectations, he doesn't actually MAKE CHOICES, he simply does what his parents expect of him.

He knows his father won't be pleased with him for acting, and he does it anyway. That's a huge step, not so much in coming out but just in learning to be his own person.
