Jason 's father
I do not think Jason 's father would have been that cold hearted, especially since it seem as if he too was a single father, after Jason's mother died. he totally turn his back on his own gradson?? and the stepmother, was acting like a total bitch... which makes me wonder what did he see in her in the first place to make him want to marry her. I understand tough love, and all that..but Jason father and step mother came across as sub-human..maybe him and his sister should have reminded them that they will be old one day, and will probably rot in the worse "Nursing" home in the world.
