Episode 20 of "Sabrina, the teenage witch"
s01e20 Meeting Dad's Girlfriend

Preparing for her father's monthly visit, Sabrina anticipates the teenage trauma of introducing her father to her boyfriend (actually, Edward and Harvey do reasonably well), but isn't prepared for the teenage trauma of meeting your divorced father's new girlfriend, an attractive supernatural lawyer named Gail. Initially hostile, Sabrina is persuaded by her aunts to see reason and tries to make amends by asking whether Edward and Gail plan to get married. When they simultaneously answer "Yes" (Gail) and "No" (Edward), Gail furiously dives into Sabrina's magic book. Attempting to follow, Sabrina must appeal to the magical Index Man to help her locate Gail's page (presumably the equivalent of using a search tool to find a web page), and tries to persuade Gail that Edward is still traumatized by his divorce and needs more time to consider commitment. Relenting, Gail rejoins the family game of magical charades.
