Somebody is obviously trying to cover all the bases. That’s just good thinking. If ghost are real, they get zapped. If they aren’t real, they get to chase a group of adolescents all over the place for about 20 minutes before said adolescents figure out it’s not a ghost for the umpteenth time.
Not surprising. Either this was their long game or MS is in crisis mode, because lately they haven’t been doing so hot.
