AMC: Did JANET Kidnap ERICA ...?

I don't think Janet from another planet is that smart to figure out all the electronics's such as the camera and the distorted voice thingamajig.....we know now it is not Krystal the woman's hand they showed the other day had her nails painted red....today they showed Krystal waiting the table when Jack was sitting there and her nails were not polished....I would say Barbara is a good guess.
