Synopsis by Brian J. Dillard
Immediately after the events of "Belonging," Cordelia (Charisma Carpenter) makes her way through the Host's home dimension, Pylea, a multiracial, medieval society where human "cows" are enslaved and forced to perform menial labor until they die. Abducted and sold to a miserly wench, she communicates illegally with an escaped "cow" who turns out to be Fred (Amy Acker), the student physicist who disappeared five years ago from Los Angeles. Back on earth, Angel (David Boreanaz) and the Host (Andy Hallett) search for ways to save Cordelia. Although Loren is loathe to return to his home world, a psychic friend (Persia White) convinces him it's his destiny. Gunn (J. August Richards), too, has issues about heading to another world from which he may never return. His neglect of his old street crew has left him guilt-wracked, especially after one of them died. In the end, he and the Host both pitch in with Angel and Wesley (Alexis Denisof) as they hop in Angel's car and open another portal. When they get to the other side, Angel is delighted to discover that on this world of two suns, neither one burns him. Unfortunately, the realization that the group's magic-tome ticket back to earth didn't make the journey with them puts a damper on any celebration. Captured by demons, the visitors are brought before the queen of this realm, Cordy, whose visions have convinced the populace that she is the messiah for which they've been waiting for generations. Originally broadcast May 8, 2001, on the WB network, "Over the Rainbow" marked season two, episode 20 of the supernatural comedy drama. This four-part saga continues in "Through the Looking Glass." In a brief subplot, two new Wolfram & Hart lawyers, including uber-bureaucrat Gavin Park (Daniel Daye Kim), are introduced.
