Theory Hopper is Wills dad.

Ok I have a theory by what I'm seeing so far in season 2 and many indications from season 1 that Hopper is Wills biological father. In season one Hopper took a real interest in finding Will as if he was his own child causing other cases of disappearances such as Barbs to be neglected also Wills absent father seems to have a hatred towards Hopper personally. I'm only on episode 3 season 2 so I'm not that confident in this theory.
