the roller blades- and red and green glasses damn it damn it damn it DAMN IT I can totally see Harley fighting bats on skates- and she'd probably be able to slip past Bruce enough times to call it a game of "wack-a-bat." (bruce of course would use trip wire to send her tumbling later but damnit) and riddler- he'd hide clues in old-school 3-D monster movie film (Tyler Durden style)- just to make bruce sit through one wear'n them- at least once for shit and giggles. hnnnnnnnngg *flails*
So lovely, this entire series is just fantastic! Loving the 3-D glasses on Riddler, and the lil skates on Harley. Everything just fits so well, doesn't feel forced or out of place ( for the entire series).
