ok so i'm on vacation. but before i left i watched an episode (i think it was from season 2 or 3) and it had a character in it that looked really fimiliar but i can't remember the episode title. and its been buggin me ever since. ok so it was the episode where the woman was found dead and her kid was given to the murderer's sister (libby) to take care of. any help would be great. thanks!!
