But when you got there the bomb was close to going off so you grabbed Jason but when you were about to escape the Bomb goes off and Both of you don't make it, soon both of you came back to life toughter at the same time and became Anti-Heros toughter, he's Redhood and u were Bluehood, you basically look like him but blue (Jason is 24 and ur 23)]
