Sarah Frosbisher-Smythe is a confused elderly woman that gave Nina the eye of Horus necklace. When she's in the middle of a conversation, she will often get into certain details and then drift off, so Nina can only get a certain amount of information from her at a time. Going by the alias of Emily Grant, she lived at a nursing home near the Anubis House. She meets Nina in the first episode when she is sitting on a bench in front of the House of Anubis. Nina brings her back to the nursing home where she lives and she gives Nina her necklace as only she can find the Cup of Ankh. Since then, Nina would visit Sarah whenever she and Sibuna needed clues. It would be later revealed that Sarah's parents were apparently murdered by Victor's father, with Gustav and Isabel Zeno becoming her legal guardians, in order to force her to reveal the location of the Cup of Ankh as she was also a Chosen One. Eventually, having lost contact with her, Victor found Sarah in the rest home and arranged for her be taken into Anubis house. Though mistaking Victor for his father at first, Sarah regains her full memories and makes her peace with Victor before returning to the home. It would later be revealed that Sarah died later that night, leaving some of her possessions to help her find the rest of the Puzzle pieces. In death, her spirit continues to guide Nina until the Cup of Ankh is restored. In the season finale, both Sarah and her parents finally rest in peace with the Curse of Anubis being broken at long last and entrusting Nina to keep the Cup of Ankh safe.
