After their initial meeting, Leo commented "That little elf? Got a big mouth." The Elf Nanny told her potential employers that she didn't cook, did only "light" housekeeping and wondered if she was "expected to protect the baby from the incessant demon attacks." Just as Piper tells the Elf Nanny that demons "rarely attack us in the house" a battle erupts in the living rooms. The Elf Woman promptly tells Piper to consider her application withdrawn and then disappears in a puff of green smoke.Later on in "Oh My Goddess!" an impending mystical battle forces many magical creatures to seek refuge at the Halliwell house, the Elf Woman among them. When the Nanny hears baby Wyatt crying, she reminds Piper "No, I rejected you. But I suppose I could fill in, just for a bit. To which Phoebe comments "Did she just hire herself?" Upstairs, the Elf Nanny comforts baby Wyatt by waving her hand and magically wrapping him in a blanket. When Leo asks "How'd you know he was cold? the Elf Nanny simply smiles and says "Babies are what I do." Of course, Piper and Leo hired her as the baby's nanny.
