@ Devo : this little gif reminds me the special bond those two had; they barely share a word but you could feel something was going one between them. Summer mimicking the girl is hilarious; then the hispanic girl (don't remember the name), applied make up on Summer and teach her in that domain. If you remember correctly, we saw Cameron applying make up on numerous occasions, which can sound weird because she's a machine : there was the lipstick scene ("tight present", "i'm a bitch whore"), the mascara scene ("not sharp enough for brain surgery") with John and then the finger nail scene also with John ("smells polish?"). And on each scene Cameron was completely off-beat, which created the comic element. No need to say Summer Glau played these scenes perfectly, creating at the same time an even more engaging character.
That is a great scene. It reminds the viewer that Cameron is constantly modifying her own programming by learning how to emulate human behavior. The part with the makeup illustrates this too, she is always learning how to better blend in. Not only that, but she starts to censor herself and become more tactful when dealing with humans. You have to wonder what protocols she would be going through for each and every action.
Cameron and The Chola were both tough chicks who stood watch over their households. They were sort of kindred spirits. They could have had an awesome spinoff.
