Even assuming Jag and Blue are mafia, after Polar’s flip that’s a team of 6.
I don’t trust Charles’ census that much, but on the off chance that it’s real, we’re missing one more mafia (actually 2 more since the number increased by 1 after someone joined them last night) and for the remaining 2, my PoE will be something like this:
Stargate
Yoho
Hayumi
Saber
