We are given some hints about who exactly is trying to get rid of the clones. It's hinted at that Evil Clone belongs to some religious group. It'll be interesting to see if that's all there is to it or if it really was what Allison (Soccer Mom Clone) surmised and that they are an experiment that someone is trying to stop.
Speaking of Allison, I've got to hand it to her, once again, for adeptly playing Allison pretending to be Sarah. It was an all around great sequence.
And Evil Clone pretending to be Allison in a weird hat that should have caused a bit more alarm, I think! LOL. I thought that was great.
One thing I did have to laugh at a bit was the use of Kasmia (Dreadlocked Student Clone) because yes, she is studying to be a scientist. And she's smart. But they seem to be using her as a more catch-all brain box. I thought it was a bit funny she was the one who found out about the knife. I mean, I guess to be a student she has to be really good at research! So maybe it makes sense.
