"No." Batman stated flatly. "He didn't." Batman felt a lot of things related to Jason: love, grief, anger, guilt - one thing he didn't feel was self-pity. His words were meant as a simple statement of fact and an acknowledgement of his own failure; is greatest mistake as a parent, as Batman, and as a human being.
"Jason always felt he was second best, and a lot of the things I did only reinforced that opinion. I tried to help him by treating him like he was Dick, but there were things in his past... I should have gotten him help, Clark. Alfred wanted to, but I remembered how hard it was to go over and over and over things... I thought it would be better for him to just put it all behind." Batman was quiet for a moment, remembering reading the police records and being so sure he was doing the right thing. "Alfred was right," he laughed softly. "Alfred's always right in the end, isn't he?"
Standing, he took the book back from Clark and looked at him. "When Damian broke in to the Cave, he took Jason's tunic from the glass display case. When I brought him home, I put it back, but a few days after, there was an envelope taped to the mailbox. A picture was inside; it was of Jason and I at a football game. The note attached said that it was a placeholder until what had been taken was returned."
Batman stopped, not wanting to continue until he thought over the evidence one more time. "The amount of people who would know about the missing tunic, and the book collection, and the diner - who would even have a coupon to a long-closed diner, and that picture, who would choose that particular book, and who would know where I would be tonight, and when..." He looked at the book in his hands, unable to face even his best friend as he said what he was thinking.
"Either someone from among my very close, very intimate circle of acquaintances is behind this, or - somehow..." he looked at Jason's grave again. He couldn't say it out loud.
