*If* there are indeed 2 of them and it's not a huge hoax, I think the key is to know which of them hates the other one more. They certainly do not hate each other equally -- one will always hate the other one more. Maybe he's jealous about something. Maybe he just flat out hates him for no reason. But there is a hatred imbalance, guaranteed, and I will almost always bet on the one who hates more. Kinda like how I was inclined to pick Caturday in his feud with Moon because he hated Moon more while Moon didn't really care.
