Two-Face has a rival. His name is Schism and he has literally two brains. With both villains at large, the threat to Gotham--and the Dark Knight--is redoubled. Or rather, quadrupled.
Batman learned Harvey Dent had escaped from the newly rebuilt Arkham Asylum. Two-Face broke into his old apartment and stole some stashed files. Batman met with Commissioner Essen-Gordon, who told him she'd be moving to a new position under new mayor Marion Grange. Batman tracked Two-Face to a circus owned by one of Dent's untried cases.
