I was under the impression that this is from 2×12 In the Name of the Brother. I could swear that the “O” magnifying glass has always been there. Here is a montage of opening sequences http://www.youtube.com/watch?v=osq8wpz5l2A.
I did notice that this one looks more black & white, like Frankenstein’s world. I saw a promo showing Rumple in a chair wearing the cape and the background was black & white as well. Maybe the cape is a cloak that helps him be in Frankie’s world?
