Harry thought about saying that he was watching that, but he didn't want to argue with his dad. Not just because when they argued it was always just Harry sputtering and his dad being all Norman Osborn. No he didn't want to rail against his father, he was just happy that his dad was okay.
He looked okay after all - really okay. And Harry figured this was a thing his father would lie about (you didn't show weakness) but if he had been that sick that he would have started making plans and - that he would have told him. Harry really believed his dad would have told him.
"Oh- Okay." The smile unnerved him, and then he felt guilty. A dad smiles at his son, and the son just wants to crawl behind the sofa? Yeah, there was something wrong there. "Lunch sure." His dad always said they'd go for food and they didn't but that was okay, because he was okay.
