Maybe it is this page, Judoh? At least it's a page where I read some theories long ago, don't remember what it exactly had and I recall this page had a different structure back then. But by clicking on the links you do get to different theories. I have actually written one about EP4's final riddle being about a bomb and golden butterflies maybe being a lighted fuse.
I guess I'll stay away from these forums for a while, avoiding EP8 spoilers... Also, beware of Youtube comments, they can be fatal.
