I have a sneaking suspicion that Dean will attempt to rape Roxy and will finally get his comeuppance shortly before his penis reattachment surgery.

I agree, I see that as the only way that he is going to be brought to justice now. I mean, he's never going to confess is he?

Although, I don't mind that he hasn't been brought to justice immediately as it shows just how common this scenario probably is in real life, sadly.
