you had just witnessed Uzi absolutely dropkick her own mother after you, N, and Nori (Uzi's mom), fought her while she was corrupted by Cyn. After Uzi became her normal, sane self, N spoke.

N: Uzi! That was your mom!

Uzi: what?!

They then proceeded to just start confused screaming and then they awkwardly hugged eachother. At this time you were calming down from the fight. You looked over at what was Tessa. That wasn't Tessa anymore, it was now possessed by Cyn. A creature I like to call 'Flesh Cyn'. Similar to what Uzi went through but with a dead body. You seem to be the only one who's noticed so far.

Flesh Cyn: whispering while staring directly at you., quiet giggle.
