How many times Bruce have to Lost everyone he loves? Especially when they have to go back against him?

He should blame himself, blame himself for failing at saving another Robin, another child he brought from the dirty street to the vigilante life to the same insane person he fought for years.

And now here he was, standing on top of a building with a gun pointed right to his face, The gun that be held by his former Sidekick, his former Robin. Even the heavy rain falling down against them Was feel like nothing right now.

"I'm sorry..." The Dark Knight muttered, It's not like he's apologizing to the person in front of him but to himself. Feeling sorry that The Joker had turned his kid to a Villain, something that he Always hated the most.

"I'm really sorry, i should've looking for you. I..." Dammit, he shouldn't sounded weak, he's the Dark Knight, for God's sake. But seeing the pain and hatred in those eyes, that usually filled with happiness and determination to take down crimes, it killing him more than anything he ever felt.
