Oh, man, it's funny but I had the same exact reaction! I saw 2.03 in the title of this post and immediately thought "she must mean 2.04, it has to be a typo" before I actually recalled what 2.03 was about. I thought the beginning of that episode was the most disturbing sequence I'd ever seen on tv, and was freaked out the whole day afterwards. And then 2.04 comes along and just blows that out of the water as to creepifying and freaking out. I spent the whole time going O_O.
While 2.03 at least has Kiki!Victor to lighten the mood, 2.04 is just unrelenting.
