When did you actually know it was coming?

I just knew George Sr was going to die when there’s a shot where he picked up some sort of cup(?) and he told everyone “see ya’ll later”. From that, I knew there’s something. And then when Mary reminded him “4pm”. But as I think about the episode, he was also giving advice to Georgie already when he was checking the roof, so that can also be an indicator that his death is coming.

What part of the episode did you know?
