meh they coulda updated the mask, its too well known and made fun of for 2021.
Billy and/or Stu somehow survived the first and are behind all this, that's my gut feeling. Only going down that route as they need to have some sort of WTF mad twist.
Stu technically could have survived, there's theories as to how Billy could have survived such as a childhood accident making him have a steel plate in his head which stopped the bullet.
Bit far fetched but plausible to some degree
