This is indeed a superb thread. I'm going to throw in a wildcard, barely substantiate it, and then step back again to watch you two continue.

I'm wondering if the boar hunting, the growing suspicions about Amelia (including Wayne's sexual jealousy), and Wayne's race are meant to bring to mind not just Othello but Shakespeare generally. As set out in most detail in Ted Hughes' Shakespeare and the Goddess of Complete Being, in Shakespeare the boar often represents the tragic hero's splitting of the beloved woman into three: the Virgin, the Mother and the Queen of Hell. The usual cause of this splitting is sexual jealousy.

More specifically the boar represents the madness this splitting induces in the hero, which in Othello’s case led to him murdering Ophelia, in Lear’s case to his misogynistic speeches about his daughter (“scalding,stench, consumption! Fie, fie, fie, pah” etc), Hamlet’s vicious turning on Ophelia, and so on.

For me, this would help account for the fact that we’re being forced to suspect Amelia (as least as events are being narrated by Wayne) while at the same time our gut (or mine at least) is telling us this can’t be right. This is precisely the split experienced by Shakespeare’s heroes, and that Wayne may be experiencing too.

The boar then gives the tragic hero a (psychic) wound he never recovers from. This too seems to have relevance for Wayne.
