1. This is a post-crisis timeline (1986-2011). I’ll be referencing a few pre-crisis panels, but I won’t be touching the New 52 or anything after it. That’s a different game of ball with its own, extremely bad, timeline.
2. Crisis on Infinite Earths is a 1985-1986 series that rebooted the DC timeline and altered some backstories, including Jason’s. Pre-crisis, his backstory was almost identical to Dick’s. Post-crisis, he changed to the “steal the wheels off the Batmobile” origin. Anything written before 1986 is a weak source for my purposes.
3. My original question centered around Bruce’s age through the process of meeting and acquiring his children. In this timeline, those children are (1) Dick Grayson, (2) Jason Todd, (3) Cassandra Cain, (4) Tim Drake, and (5) Damian Wayne. I was envisioning an interview where the kids explain their family timeline to outsiders. I did not anticipate the project taking this long.
4. We’re talking about 72 years of content here, which means decades of contradiction, conflation, and rewrites. I’m pretty satisfied with my work product, but please understand that there are no perfect answers. I’m going to cite my sources, and I’ll do my best to explain why I chose those sources specifically, but it’s pretty likely that for every panel I pull, there will be others with different numbers. We’re all going to have to live with that.
