It made no sense.
If Jas were a Traitor, he knows who the Faithful are. So from Mollie's perspective, knowing she is Faithful, it's either:
Jas is not a Traitor and truly believes Harry is. Let's be safe and banish Harry. I'll split money with him if I'm wrong. Vote Harry.
Jas is a Traitor and Harry isn't. I know I'm not, so why the fuck would Jas vote to banish? He doesn't need to off Harry, he just needs to stay in the game. He'd vote to end if that were the case. So this can't be right. Vote Harry.
They're both Traitors and Jaz just wants more of the pot. In this case, I've lost already, so my vote doesn't change my outcome. Vote either Jas or Harry, doesn't matter.
There's literally no scenario where voting Jas improves her outcome. At best it leaves it unchanged. At worst it costs her the game. Whereas voting Harry means that at worst her outcome is unchanged and at best she wins.
Ugh, I know we all know this but it's so infuriating!!!
