Bruce usually is an ardent supporter of the justice system, even if he works primarily outside of it. Obviously it's not perfect - thus the need for, well, him - but nothing is without flaws, and he wants to believe that it is, for the most part, a good thing. He believes in justice, and if this is the system through which it is primarily enacted, he has to believe in the potential of that system to do things right.
But sometimes, it does things very, very wrong.
It had been a frame job, and the Bat and his extended Family had been the targets. And you - you'd taken the fall. He hadn't agreed - you'd done it anyway. And in the end, there'd been nothing he could do but turn his focus to setting the record straight and getting you out, as soon as possible.
Because there was no way that incarceration at Blackgate Penitentiary was going to go smoothly for any associate of the Bat.
And he had gotten you out. He'd done his detective thing, he'd proven that you had been framed. This had revealed another flaw with the system, though - it could be slow. Arranging your release had taken so much longer than he'd wanted it to.
But now you were home. At least there was that. He didn't know all of what you had been through - but he could imagine it. He'd seen the new scars, the haunted look in your eyes. But you were home. Back with your family, safe. He wasn't naïve enough to think he could just 'fix things', but he'd be damned if he wasn't going to help you however he could.
And right now, that means bringing you a nice warm drink. "Hey." Bruce puts on his best gentle smile as he approaches where you're curled on the couch. He doesn't want to sneak up on you - best to announce his presence. "How you doing today?" He tries his best to sound casual about it, and holds out the mug to you.
You have good days and bad days - he's hoping that you being out of your room suggests today might be one of the better ones.
