i dont think his dad molested him at all. they were just very 'close' in a weird way.
i mean i did get that vibe, but his dad seemed way to macho to be a diddler. basically, he loved andy more than he loved himself....Andy was his all, his protege.
that scene was probably the director just reaching for some ambiguity. I believe modesto was just turning off the light, nothing more
Yeah I don't think so either. Still there was enough trauma to turn him into who he was.
