At Gotham City Airport, Jason hops on a plane and flys to Syria . Batman hops on his jet. Joker gets in his helicopter. All to get to Syria.
Jason finds Sheila Haywood at a church mission. They talk and go out for lunch. Sheila then leads Jason to a warehouse where she apologizes to him as she was working for the Joker in exchange for her life.
Joker then reneges and shoots her in the head. Then he starts beating Jason with a crowbar. "Poor Jason, I almost feel pity on you, I could let you go. Nah. I'm just going to keep beating you with this crowbar. " "Go to hell!"
Batman pulls up "That's my cue to leave! Bye."
The room explodes.
Batman looks for Jason then he sees the body. "Jason" "NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!"
With that, Batman vows vengeance on the Joker.
