Hallie once had a computer chip in her chest that when hugged, would cause her to say the sorts of things a nurse might say. Doc was entirely unaware of this until the chip migrated to Hallie's foot, annoying Hallie by causing her foot to "speak" whenever she would take a step. After having her mother remove the chip, Doc chose for her to not to not replace it, since she didn't need a computer chip to make Hallie talk.
