sylar has his powers back. nikki and nathan are possibly dead. but they can always come back with some back door escape and an injection of peter's blood. peter may have the virus. does he? adam is buried with hiro's father doomed to live forever in a coffin. maybe in 500 years there will be a flood that will unearth the coffin and he'll escape. maya is still hanging around doing nothing good with her power.
and just in case you forgot, i did indeed meet sylar.
