Superbird and opaltiger are dead.
Notes:
opaltiger was mafia
-- possibly bus driver or bodyguard?
-- OrngSumb says he vigilante-killed him
Superbird was not mafia
-- possibly vigilante kill, due to flavortext? ("There is something strangely off about it; what kind of Mafia uses knives to kill people?")
Blazhy roleclaims as 'someone who can see who targeted a person during the entire game'
-- says that the only one who targeted opaltiger was OrngSumb
OrngSumb declares he is not bus driver, 'got very lucky with his night action'
-- Butterfree suggests schizo of some sort
-- OrngSumb roleclaims as plain old vigilante
Flower Doll roleclaims as doctor
-- healed me ♥
