If Brie's been in Steph's body for days, what's going on with her body? Is it in a coma?
It would be great to get a second part where the little sister wakes up possessing Brie's body and the change is made accidentally permanent.
A lot of the time when I think of possessions, I think of the person, as a whole, becoming...a spirit or something like that. And then they just jump into another person's body. So their real body isn't really around anymore. Does that make sense? lol
