Fridge / What We Do in the Shadows

• Of course vampires don't turn their Familiars. They lose a valuable servant and have to get a new one. Besides, familiarity breeds contempt.
• Nick's transformation into a vampire is actually just him dying, suffering the sort of rigors corpses undergo.
• How did Deacon get into Nick's backpack to attack him during the chase scene? Only a few seconds before, we see him getting swooped on by a bat that attacks the back of his head. Deacon mussed up his hair then quietly slipped inside the backpack so as to transform and grab at him when his guard was down.
