They are so dense. Zack in particular was going on after the round table that there was only one traitor left to find. Why is that the case? He is so blinded by his belief in his own superior intelligence.
If they murder Zack, Jasmine gets banished tomorrow, they murder Jaz and then Harry strategically feeds Mollie’s seed of doubt about Andrew, get him out heading into the endgame and Harry gets to go ‘oh great, we got that last Traitor, we won!’ and shaft Evie and Mollie. Mollie will still be trying to work out what happened by the time it airs.
Jaz has no hope convincing any of the people left that Harry is a Traitor, they are too closely aligned to Harry and Jaz doesn’t have the influence to sway them. I hope he feels vindicated watching it all unfold.
