"From what we understand the rape stemmed from an argument between him and his brother. And apparently they were arguing over a girlfriend. And the rape was some sort of retaliation towards his brother,"

Mom's passed out drunk, these two retards argue, and the loser of the argument attempts to even the score HOW?

Sounds like a discarded scene from Sling Blade.

The fact that he would do this makes me wonder whether they've done it before- like "consensual" incest. Then he must have assumed he could just do it whenever he wanted, without asking.

My theory.
