Up until now, the show has been intriguing and occasionally witty, but in this episode things start to get creepy and crazy. It opens with a very gross self-surgery on the part of last week's blonde clone. I found the hotel room confrontation at the end a little bit anti-climactic, but the rest of the episode made up for it in ambiance. The blonde clone's motivation was revealed this episode, and I thought it was very interesting and realistic. One big theme of this episode was clones pretending to be each other. Sarah has to pretend to be Beth so that she can investigate blonde clone, but she also has to go see Kira or Mrs. S will block her out forever, so she enlists the help of Alison, who pretends to be her. While this is happening, blonde clone takes the opportunity to pretend to be Beth and infiltrate the office. This led to several spine-chilling moments, the highlight being when Sarah saw what blond clone did to the evidence on the board. Overall, very well executed episode, if a bit anti-climactic.
