I'm surprised that Cindy's VA actually spoke fluent English (though upon looking it up, it seems they just used an English(-speaking) VA for it). And also that she was shown as being a rather normal human being. The language barrier with Eiko was great, though if I must name one flaw in that first part, it's that Cindy suddenly didn't understand that Eiko was speaking Japanese. Oh well, it made for amusing misunderstandings anyway.
In all aspects, this episode was brilliant. And we got our favorite mini-cephalopod back as well. =3
