"If for a second I knew you were alive, I wouldn't stop looking for you!" Jason yells, desperately trying to make you hear him, but your deafened by rage, by wanting nothing but revenge against Jason. You believe— or Joker made you believe the Jason left you, abandoned you, leaving you with that fucking, crazy clown, but the truth is, Jason saw a video of Joker killing you, so the stopped looking, stopped searching. That was a grave mistake. Jason is not afraid of that gun, which you're holding against his head. He's not afraid of you. He doesn't see you as a bad person, yet knowing that you were alive, tortured by that clown and knowing that feeling himself, those made him see himself as the bad person. If the man knew that you were still alive, some were out there, he would never leave his younger sibling, you with that monster, never.
