I could see her making an appearance at the red carpet somehow and maybe in the lobby. Eric just has to do what I do with Muley and tell the photographers "Shoot HIM from the waist up, or you'll lose the magic," and normally they will. In the meantime, I normally stand behind him and look away, so it seems that, instead of being his puppeteer, I'm like a weak-looking body guard or something.
After all, on name tags it always reads:
Muley, A Mule (or Talking Mule)
Kevin, Muley's Person (or Personal Assistant)
