Steph's been getting this attitude since she began, so I almost think that she'd associate it with the cape & cowl set. And really, her reasons for getting started (to stop daddy Cluemaster's latest crime spree)aren't any worse than anyone else. I mean, Tim started out as stalker!fan, who was trying to convince Dick to go backwards & become Robin ... I think that Huntress & Steph have gotten equal amounts of attitude from the Bat clan, precious little mentoring, and wtf! when they don't follow the rules that no one explained to them. Yeah, Steph's had her fair share of screw ups (and some of those are doozies), but Cass got the yellow brick road in comparison.
