"Wait, you... what?" Bruce nearly choked on his coffee, spilling some of the liquid on his shirt as he turned to you with bewilderment etched on his face. It was more of a common occurrence for someone of your age to like the Caped Crusader. Most of your peers would usually look to the rooftops in awe at night to catch a glimpse of the Dark Knight, but not you. Obviously, Bruce didn't expect you to worship or overtly idolize him, but he definitely didn't expect you to admit that you hated him.
Grabbing a napkin to wipe the spill off himself, he used a feigned state of discontent as a way to stall for time until he could think of what to say and to hide his initial reaction of shock. Great, your confession completely threw a wrench in his plan. He was planning on telling you the truth, hating that you were kept in the dark and making up some type of scenario in his mind where you'd be in awe after showing you around the cave and maybe a few of his gadgets. He just wanted to gauge your opinion on the Caped Crusader before he made any final decisions. Thank God he did. That would have been embarrassing, more embarrassing than spilling coffee on his favorite turtleneck because of a child's opinion. For a hero who had a plan for everything, he certainly didn't have one for this.
"Well, I can agree that he doesn't use the most... orthodox methods of crime-fighting, if that's where you're going with this." He chuckled softly while scratching the back of his head. More attempts from his side to defend the hero's morals and methods were met with your nonchalant criticisms. He was more offended than he'd like to admit once you brought up the batsuit, unknowingly jabbing at his ego a little bit. Maybe he could try to change your mind, and maybe he won't check the mirror more than once to see if the batsuit really is as dumb as you think it looks. "So, what exactly is it about him that you're not fond of? There's gotta be more to it than what you're saying."
