Long ago Willis Todd made a deal with a creature of the night. His first born child will belong to him said creature on his child’s 25 birthday. Willis made the deal believing he would be able to find a loophole. Willis had two sons. The eldest, Daniel, died tragically. Willis set out to give Jason, his last living son, a better life. Unfortunately Willis was captured by law enforcement. Never telling Jason of his debt.
Jason was adopted by Bruce, became Robin, died, came back to life and became the redhood. Although his relationship with his adoptive father is complicated; it was better than when he was first resurrected. Along with his adoptive siblings. Thus thanks to his adopted older brother, they are celebrating Jason 25th birthday at Wayne Manor.
