ok who died on the episode last week...has anyone figured it out cuz i cant!! and i really dnt want to wait till siguiente week to find out!!!

I have figured out that its not the baby bcuz the casket is to big...and its not violeta bcuz she was standing right beside Pete...but i wonder if it was just her spirit o something cuz sam and naomi were talking and sam dicho that he couldnt have done it if he were Pete and Naomi dicho that she wasnt going anywhere!!
