I love watching Two-Face origin stories. Over and over again I'll say, "Nice District Attorney Harvey Dent you got there. Would be a shame is something were to ... physically manifest ... his bisected personality ... and he became ... some kind of two-faced villain!"
This is an exceptionally good Two-Face origin, and maybe if you all demand it on Twitter or something, I'll do a dramatic reading of the novelization I have for these episodes. Yes, it is called Dual to the Death.
