*jawdrop* I'm not the slightest bit familiar with this show, and only vaguely familiar with the story, but the way you've described it, it's like...they sound like they would both be PERFECT.

And I agree too about David = Jesus, John = Judas. There's some good arguments above, but the idea of Judas needing to be the relatable one is what really sold me.

I'm not even joking when I say we need to put this idea out to stew in the public conscious somehow. Some producer needs to pluck this idea up and make it happen. I don't even say this for selfish reasons, since I'd never get to see it. It just should totally happen.
