haha your guess is as good as mine to why they edited out Revy cursing in english.. I was actually wondering that too, since the editing actually made it kinda hard for me to understand her when she spoke. They probably just did it to make her seem more American, since they edit out all the cussin in the states when a show isn't on cable. Besides any other explanation, other than they just felt like it, wouldn't make much sense since they curse in the opening anyways..
Anyways I also liked this episode. Like everyone said, character development is always good. And seeing a softer side of Revy is always a plus in my book =)
