I think the strategies to get to the final are :
work out who a traitor is and then buddy up to them whilst acting dim as fuck if you are a faithful. do as the traitor directs
take out your fellow traitors if you are a traitor
Once you get to the later stages you want to be on the right side of block voting. So being nice, but dim and not sticking your head up too much works.
Meryl has perfected this. She is nice enough but dull and thats why she's made the final.
Hannah buddied up early on with the right traitor
My expectation for next series is to see it more tactical with faithful perhaps correctly identifying their buddy is a traitor but deliberately trying to keep them in until the late stages as the alliance is more important than getting the traitor out.
What Wilf has been best at is timing and understanding the right moment to make the right move against the right person.
Alyssa was a liability and it become him or her so he ensured he survived.
Amanda made a massive error with Theo and went for him in logic I don't really get. Wilf nearly got caught out doing the same thing with Hannah over the who do you trust game but got away with it because it wasn't a banishment. I don't think he would have had it been.
Amanda's error was noticed and that made her vulnerable. Wilf did take advantage but it hadn't gone unnoticed by others.
I do think that Hannah is the one to watch tonight. She holds the keys to the final.
Her loyalty to Wilf isn't matched by any other relationship in the group. I can't see her shifting loyalty from Wilf to Kieran at this point. Something may happen tonight and she may do, but as it stands Kieran needs to play a blinder to beat Wilf.
There is 5 left and they KNOW there is at least one traitor left. They will keep voting off someone until a traitor has gone. So an alliance between Will and Kieran won't work unless they can both get to the final 3. They both will have worked that out.
The numbers mean that if Will and Hannah can survive the first banishment tonight, its extremely difficult for Kieran to win.
If Will and Hannah survive its 2 v 2.
Both Meryl and Aaron can be manipulated easier, so I think this is Keirans problem. Taking out Hannah gives a better shot at taking out Wilf. But leaving Hannah and teaming up with Wilf to get to the final three works too. He will probably struggle to take out Wilf without taking out Hannah first.
Wilf will want to take out Kieran though I suspect. For much the same reasons. But if he tries this in the first round where he hasn't got the numbers he leaves himself more exposed. He would be better to hedge his bets and take out one of Meryl and Aaron to get to a 2 v 2 situation where the balance of power tips in his favour.
I am therefore expecting the first banishment to target Hannah in someway. Whether she survives determines the game.
