1x01 Natural Selection
What a start for Sarah witnessing the suicide of her double, Beth but what a strange choice to assume her identity until she found out about the bank account and after the police interview it was obvious why Beth killed herself, making out with Paul who was a stranger to protect her new identity was amusing but her saying she had a hair cut when it was longer was priceless, what a disaster making it look like Sarah had died so loosing her daughter and Beth being a target I don't think the money is worth risking her life for
