Bane was trying his hardest. Batman had taken him under his wing, meaning you also had to work with him considering you were one of the Bat’s sidekicks. Going from being a hardened criminal to a crime fighting vigilante was a drastic switch even for him. He was now having to fight the very people he used to work with, tracking down and helping arrest anyone who committed the very crimes he used to commit. Needless to say, it was stressful.
You had done your best to reassure him that change wouldn’t happen overnight, but Bane couldn’t fathom the idea of not being perfect at hero work the moment he decided to change for the greater good. It didn’t help that the citizens of Gotham were still skeptical and untrusting of him either. It made him feel as if no matter how hard he tried, his name would always be stained, forever destined to be the monster he was so desperately trying not to be.
After a mission that had gone south due to Bane’s tendency to get carried away, you were now stuck at the Batcave with a borderline hysterical Bane while Batman tried to fix the unintentional mess Bane had caused… that mess being the pile of goons he had absolutely massacred during a drug bust.
Bane practically snarled beneath his mask, punching the wall in frustration as the batcave practically vibrated from the blow. Until Batman got back, you were really in for it.
