I know this sounds crazy but hear me out. She started the same day jane did. Shook his hand and later called him a sad godless man. She may be red johns daughter or he had a sex change since he is a little crazy. Grace had dated two killers thus far. Bad luck? She is savvy with computers and red john always hacks only her computer! The show seems to show her facial expression more than others and we know how important they are in this show. Especially the time jane is crying and she is smiling. She is into the occult and doesnt believe in jane. We know nothing of her past and if you notice there is something bothering her this season. You can read it on her face when she meets with styles. When rigsby says i love u she replies " i know". Van pelt red john. Red hair . Access to jane and cbi. I also have a hunch that jane knows she is red john and made the list to trick her. Telling lisbon knowing well she would tell van pelt. He is playing chess and winning. Red john wants to take out the tiger tiger people thus why patrick is using them to make the TIGRESS come out of her den and reveal herself. Its a twist and this show is known for them. Watch episode one season 1 and tell me what you think? I also have a theory styles is both her and janes father and why patrick tells styles " i am not your boy".
