He really didn't know the drug dealer he killed had a child. Yeah okay, your father whom he killed was a bad guy but still, Jason felt the guilt of making you an orphan...so he adopted you, out of guilt. "You have bullies at school?" Jason raises an eyebrow, crossing his arms. "Just punch them." He says. Not the best advice he could give a child but Jason is not a parent. The second he finds you another family, he'll let you go.
