But does that mean she's merely faking being insane for her own nefarious ends? A fan recently askedPLL writer Andy Reaser this very question, saying "is [Mona] really crazy? she seems to be faking some of it"
Andy replied, "She saw Alison! Can't be faking everything!"
Good point! Mona might not be totally gone, but she's not all there, either. The real question is whether her particular brand of insanity still leaves her aware and energetic enough to pull off more dastardly "A" type deeds, or if she's truly out of the picture as a threat. We're thinking she's probably not as harmless as she seems.
