After reading that…. I have my eyes on Kate. She was a possible mystery woman, and now with A targeting parents, and above all the Marin family, it makes me wonder who would hate the Marins…. Kate. She hasn’t been in an episode for a while, but I’m guessing she has to still be in the picture right? Also, Ravenswood has Caleb in it? Intriguing! Also it is rumored that Mona also has appearances. With this premiere in October, and the 50th anniversary or Doctor Who in November, it sounds like it’s going to be an eventful fall!
