In the unlikely scenario that CTh shot himself and Dake is scum with Tanz/Navi and took credit for the kill, Gumica could be town, in which case he can shoot Dake to stop us from losing, because Gumica can only be town if Dake is scum.
Otherwise feel free to try and shoot me, you obviously can't. I've been hinting at him being able to do something if he's town, but it's an unlikely scenario in the first place, and he isn't doing anything.
From Dake Tanz and Navi's POV, Gumica+Drezi team is impossible already, since that would mean the 3 shots claimed by you guys are all town, in which case scum would still have their shot, and would have won by killing a random townie. [Dake, Navi, Tanz] one scum here is confirmed from everyone's POV (as town you exclude yourself obviously).
So I can just shoot Gumica, since me keeping my shot shouldn't make a difference at this point.
