Gene is a good example of what can happen if a wound isn't treated. Sometimes they heal without help, but sometimes they fester. Gene has a festering wound, but since it's inside on his soul, it's not visible to others. droughtquake noted the parallels with the events in Brittle as a Bird, but I couldn't help notice that this time it was Star who got Gene out of that loft, not Joey. Could that be that because of Gene's festering wound he couldn't take the pain of Joey being too close?
Coach Arnold is another example of a festering wound. Something happened to him at some stage to make him someone willing to murder. That's not a simple hatred or dislike -- that's something much worse. We don't know what it is, but there has to be a cause for his behaviour. Until that cause is addressed, the Coach's of the world will still be out there causing harm. I'm sure there will be people who will blame religion, and I agree that religion can be a cause, but that's also too simplistic. There are non-religious people out there who also carry hatred of gays.
Getting back to the story, I hope both Joey and Douglas come out of this okay...
