Crane later summons Rachel to Arkham Asylum and shows her that the toxin, extracted from the same blue flower used by al Ghul when training Bruce, has been introduced into Gotham's water supply from Arkham for weeks, and once Rachel is infected, Crane demands to know who else suspects him. Rachel is saved by Batman, who overpowers Crane's thugs and sprays Crane with his own toxin and races across Gotham in the Batmobile with police in pursuit, before administering the antidote.
