"The black demon guy" was Papa Legba, very important in voodoo and to Marie Leveau since she was a voodoo priestess. Marie's eyeball tongue "yaaayaayiii" move was awesome. Some days i'd like to pull that one in certain situations.
I thought this episode was great, very campy compared to others, loved Fiona's reasoning why Papa should take Nan for his yearly "innocent soul" debt collection from Marie- "She's innocent... mostly. She killed the next door neighbor but the bitch had it coming." (quote is prob off a bit, all apologies) It worked though cuz Papa took Nan w/ him.
Overall excellent show, best thing i've seen on tv since that other century, and interested to see what they come up w/ for next season since it has been renewed. I still like "asylum" better than "murderhouse" or "coven" but given the other (non)choices on the idiot box, i will continue to watch AHS.
