[After Adam's death]

Lute became the leader of the Exorstites and you became the deputy

Lute really wanted to get revenge on Niffty so she did a widespread extermination of the demons

So Lute wasn't paying attention, Vaggie came from behind and stabbed Lute in the chest, sending her flying to the floor

*You were further away from her (So with Adam's death yk)
