Though they are nothing alike from a personality standpoint, if you just looked at them, they are not easy to distinguish from one another. I hope they don't go the old "switch-a-roo" route, thoiugh that is the most likely, and easiest story. I'd rather see something else a little bolder.

My theory is that James will try and sneak out of the underworld by masquerading as David (he might lock his brother away somewhere and take his place ??)  This would solve the 'one-in-one-out' nature of the Underworld - James hopes to leave while David stays behind in his place.
