You're thinking he'd just out himself thus won't vote for him, however if you do call his bluff and vote for Orca sure it will reveal he's lying and scum but at the same time he would of also taken out Orca whose Town
unless Orca is a vig and they know that, it's an awful play and now you lose a mate for almost no reason.
Didn't you, yourself say you had Mech that Orca was town?
But Alexis is contradicting your mech by saying he's scum
Both can't be true
So either one of you are lying
Or
One of you got messed with some how
Alexis at best misunderstood whatever his rolesheet told him and at worst is just lying as town again.
He's not even using mech, it's a passive. One that town wouldn't have.
And I really really doubt mafia would mess with my slot at the beginning of the phase when
1. I haven't claimed squat prior to this
2. Not universally town read
So for Mafia to mess with me at that exact moment with be a massive coincidence and luck
