This page is seen only once throughout the series, in the episode The Courtship of Wyatt's Father. Phoebe and Paige ask Gideon about Portals in order to rescue Piper and Leo from the Ghostly Plane, where they have been sent due to a joint plan between Darklighters and Gideon. Their intention to remove Leo, now an Elder, required them to be separate from the Power of Three and their own active Powers. In order to achieve this, the Darklighters - presumably with the help of Gideon - create a portal which sent them into the Ghostly Plane.
