My Jacob/MIB prediction

I didn’t have enough info to really throw down a Jacob/MIB prediction at the beginning of the season and still really dont and it usually not like me to follow the crowd but a general consensus has always been that the two are brothers, I think this as well, kind of, maybe like half brothers and Jacob was the youngest, their mother dies when they are young trying to save Jacob and that leaves Jacob’s father to raise them both. Jacob’s father resents MIB because he is not his genetic offspring. MIB resents Jacob becuase he blames him for their mother death. Later on Jacob is chosen as the first candiate and all the powers that go with it are imbued in him. While he is still getting the hang of it he accidentally touches MIB. MIB being the first that touches Jacob for one reason or another gets almost all the same powers that Jacob has but also his gift is to be able to take on the form of the dead (perhaps from all his mourning over his mother, to know what her last thoughts were, missing her, wanting to see her just one last time, etc.). In order to be able to that it had to be able to a transitional form (ie Smokie which was laying dormant underneath the island for however long waiting on a “candidate” of it’s own.
