Yepp, my role is Mango.
Well, they are vocal, but neither of the players you named are confirmed. Fuji investigated Nat and said she's town. Udell seems to not trust Fuji and he's suspected by Lanji for parroting reads and not contributing anything original. Zara is suspected of being a third party and bisorami bear. Mango is also suspected for various reasons.
So I am in a group with Mango and Zara and both have claimed town and I've asked for their reads as well. So far there's nothing pinging me about either of them.
