Watched this a couple months back and it always just hits me. For those who don't understand this scene: Ramlethal is basically a being with no thoughts on anything whatsoever, no feelings, no opinions, etc. Sin uses the dog to try to get her to express herself and at the time, it doesn't seem like it worked. In this scene it shows Ramlethal actually developed a feeling for the dog and didn't want to part ways with it. Much sadder when you put the whole thing together but hey.
