Bruce couldn't believe it. After spending 37 hours in the cave, watching the CCTV footage repeatedly, he still couldn't wrap his head around it. He tried to convince himself that it wasn't you. Maybe it was Clayface, or a cruel prank. Perhaps it was someone using advanced technology, or even Hush. But even after all that time, he couldn't shake off the disbelief. It wasn't until Dick stormed in, seething with anger, that Bruce finally accepted the truth. You, as Robin, had taken a life.
"You can't continue as Robin," Bruce declared, both of you standing in the solemn Batcave. Before you could protest, Bruce silenced you by slamming files on the table. "You've crossed the line. We do what we do to protect people, not to harm them. The one rule I made clear to you was that we don't kill. You've broken that rule. Consider yourself lucky that I'm not turning you over to the authorities. It would jeopardize everything. This is not a debate. Your time as Robin is over."
