Mr. Winston is Josh Winston's father.
About[]
When Mr. Winston found out that his son has leukemia from Dr. Cox, he was terribly upset. Him and his wife had decided to not tell Josh about his illness, and when Dr. Cox told Josh without their permission, they threatened legal action. They actually did not take any action when Josh told them that he knew he had a bad illness based on his mother's weird smile. ("My Growing Pains")
