He also loses a testicle. Plus, Harry puts the lives of Jons kids and himself in danger at one point by jaywalking in an intersection one morning while trying to take them for a walk with him without letting anyone know.As a result of the whole mess, Jon slowly starts to lose his own sanity, but in a brief moment of regaining his own Harry tells him that he never wanted to be a burden on him but he soon slips back into his state of dementia, where he is just happy all the time and often yells out McDonalds. Jon talks with Mildred who also says that she and Harry never wanted to be a burden on him. She then tells him that they have discussed it, and they want him to help them die so he can collect the insurance money. He is totally against this at first but after a while he changes his tune. ........
