I've always had a soft spot for the changeling mama, after I wrote a really long meta about the imagery of suburban motherhood and its discontents portrayed in that ep.

I have to ponder what I have to say about 5.15.... but one thing i think is that it points out the anachronistic quandary that spn builds for itself -- it wants Bobby's wife to be a fifties iconic woman, when really she would have been in a polyester pantsuit. :)
