Continuity mistake: When 'Brigitte' has transformed into a werewolf and is attempting to climb out of the basement via a ladder and 'Ghost' pushes her back down, Brigitte is seen holding onto the top step of the ladder, but when 'Ghost' is closing the basement door 'Brigitte' has vanished. (01:28:50)
Continuity mistake: When Tyler injects Brigitte for the first time at the hospital, look carefully at the syringe. You'll see that in the first shot its content is 1/3, and in the following shot is now 1/2 full.
Other mistake: When ghost gives B the needle in the bathroom and after Ryler takes it away and squirts it out, you can hear the needle being thrown to the side. And she instead licks it off the floor instead of just getting the needle again.
