Cabin Fever: Patient ZeroGoofs
When Marcus, Dobbs and Josh find their way into the main laboratory of the facility they are met by Bridget, Dr. Edward's assistant. She is wearing a mask that is covering her mouth area. We hear her perfectly speaking to them without any problems in pronouncing any of the words of her sentences. But when Camila, the other assistant shows up and forces Bridget to remove her mask and show them her skin we see that Bridget's lips are gone due to the virus attack. So how was she speaking naturally before removing the mask? Then she wears the mask again and in the coming scenes we hear her perfectly speaking again.
