Over the last few episodes, we've been able to glean a bit of a falling out between Bruce and Dick. This is our first look at 'Nightwing'--or, as Catwoman likes to call him, "Man Wonder." Meanwhile, Batman has to sit back and watch as his former protégé gets sucked in by Cougar-esque charms of Selina Kyle. Can Bruce let go? Can Dick become his own man? Can Catwoman be trusted? All of this and more in "You Scratch My Back!"
