A continuation of the last episode gives us Faith in Buffy's body. This makes for some very interesting and very good scenes. Buffy/Faith with Willow, Buffy/Faith with Spike, and Buffy/Faith with Riley. I believe this is the episode where we start to get the feeling that Faith doesn't really like her life. I draw this conclusion mostly from the final confrontation between the two, but little hints are dropped the entire episode. She does wish she was more like Buffy. She wishes she had friends and family that truly cared about her. She doesn't like the person shes become. It's also confirmed because of what happens when Faith crosses over into the Angelverse a little later on.
I really loved this episode. I loved that they humanized Faith the way they did. I've always preferred Faith as a good person vs. a bad person.
