I've never said Ali has a poisovenomous role, I've said there's chance (which means more than the average value but less than 100%), and if my role were so powerful as Ali claims, I wouldn't have blown my cover so soon. However, as Bok hinted, the fact that Ali started doubting info gatherers now (and not yesterday with Amine) makes me think I'm on the right track.
As for the double lynch, I think there are better targets than me, such as Amine/Ermac; the fact that Kiet voted Astra after warning us about Scorpion gives us one (or two, depending on why you think Kiet is voting for him) more possible target (or targets).
