I can't make my mind up about whether Harry has blown it or not.
The edit makes it clear that he divulged quite a lot of detail, but who knows how much rambling and other noise and theories were shared as well that were cut. There is a good chance a couple of them will start thinking about it once the excitement has worn down, but I think he can talk his way out of it and shrug it off in a kind of "look, I just had gut feeling and a mad theory" kind of way. But if he starts being too 'clever' or 'strategic' now, he's for it.
I hope he hasn't overdone it - I think he has played it brilliantly up until now.
I wonder if any of them have been noting the voting and studying it. That's what I'd be doing.
ASH: voted by Paul & Harry (amongst others)
MILES: voted by Paul & Harry (amongst others)
PAUL: voted by Harry (amongst others)
They will be able to see that Paul was voting out Traitors left right and centre and look at who voted out the known Traitors, Harry would be in the middle of the venn diagram for sure. They would also realise that any theories about Traitors being a 'group' are bullshit and see that they are out for themselves. If they start applying that logic instead of thinking of the Traitors as collaborators, they might see Harry.
Andrew just looks absolutely defeated - like he has been handed a death sentence and doesn't seem to have it in him to take back any power - I hope he perks up tonight.
