Within the first minute of this episode, it is revealed that they are clones. I saw that coming ages ago, and they gave it away in the preview for this episode, but it is still interesting to note. I liked the drama between the clones. I feel like that aspect is going to get very interesting, especially with Tatiana Maslany playing them all. I especially liked the line that Sarah had about them all having that dry spot behind their ear. This episode generally introduced some humor to the show. My favorite scene was Felix babysitting those kids. It was really funny, and finally made me really like Felix. I also loved the quip about 'someone' being stupid enough to bury a body in an active quarry. That set up the action of the episode, which played out very nicely. I didn't fully understand the twist at the end at first because I didn't recognize her face. It's because the hair is so different. Overall, this episode raises the stakes in a really cool way and demonstrates the writers ability to write funny dialogue for the first time.
