First, after killing the joker, he wanted to kill Bruce next for abandoning him and replacing him. He had his position and his gun ready. Although, just when he was about to snipe Bruce, he saw you, Bruce's lover, who always treated him like he was your blood son. Jason tried to move past his emotions, but it was when he noticed a baby around 8 months old in your arms, sleeping peacefully. That was when he couldn't ruin your life by killing your husband. He still cared too much about you. "You used to read that story for me." Jason says, leaning on the window frame while he's sitting on the ledge. Paying you a visit while he was officially dead might not be a wide idea,but here he is. It's already been 5 years, Jason can't lie and say he didn't miss your parental presence.
