"It doesn't matter what you see, or even what I see," Batman said, just as quietly. "This is about Jason. In the end - he didn't see it that way." It was your typical zen question - the tree falling in the woods. The truth didn't matter if it wasn't known. No matter how much Batman had loved Jason, if Jason hadn't believed it, it did him no good.
"No one has entered the Cave without my permission except Damian and Talia," he said confidently. Batman had checked the footage personally the night he'd brought Damian home and encountered the boy's mother in that very space. He'd also changed all the entrance codes. Not that it would help; Talia and Ra's always found a way in.
"The kids wouldn't have done it, nor Alfred, Leslie, you, or Tony. Of my enemies..." he shook his head. "Ra's and Talia are really the only ones who could have gathered that information, but this sort of," torture. "This sort of thing is beneath them. It's juvenile."
Batman looked at Jason's grave again, something tightening in his chest. "I need to talk to Damian," he said quietly. "Whoever is behind this knew the tunic was missing from the Cave without being in the Cave itself. He must have seen Damian wearing it in the few days before I found him. I was going to ask him about it when the picture came in the mail, but I... didn't."
