What I said was 'wrong' was your statement that:
"..the only logical thing that he could have done which made him scared, after the hit attempt on Mike, was to open the drapes..."
As I then said, there were MANY things that they could've lied to him about, that he could've done to help them...that would've made him piss scared after the hit attempt.
"..What could he have done that made him perhaps realize that he almost got his brother killed? Open the drapes maybe?.."
Possible. But it's FAR from the 'only logical thing he could've done' that would've made him scared.
So
that's where you are wrong.
Sure, we're speculating and it's lots of fun. As with any topic we can make up all the background stories we want. But in this case, Kay's presence in the room whether
before or
after the opening of the drapes simply defies any 'logical' answer. We can speculate 'who' opened them, but logically because of Kay lying in that bed, they couldn't have remained open until Michael was conveniently standing in front of them.
And yes, due to the activity in the house that day, in a well orchestrated plan it would be possible for someone other than a 'family member' to infiltrate the house and make their way into the bedroom to open the drapes.
What's more interesting to speculate on (in my opinion) is exactly HOW Fredo helped Roth & Ola. Because I don't think it was to 'open the drapes'.
