Gideon sends a darklighter after Leo, Phoebe, Piper and Paige but orders him only to harm Leo, not the witches. This plan failed when Pheobe fell from the roof of a builing on to a dumpster. Piper and Leo are accidently sent to a plane where no one else exsists.
Paige and Pheobe do not know where Leo and Piper have gone but they realise that they are not in this plane. Paige takes Pheobe to the hospital. Back in the plane Piper anticipates that Paige will take Pheobe to hospital so she and Leo go to the hospital.
In the normal world the doctor tells Pheobe that she has a mild concussion but Pheobe persuades him to let her go home. Pheobe goes to join Paige and we see a huge flood of injured people come in Paige tells Pheobe that a truck had hit a bus. They see the bus driver in surgery and his heart stops beating.
In the plane the bus driver appears and hears Piper call Leo by his name. In the normal world they charge the bus driver's heart and he comes back to life muttering "Leo. He must be an Angel". Pheobe and Paige hear him and Pheobe sort of "feels" Piper and says her name. Back in the ghost Plane Piper can also "feel" Pheobe and she can hear Pheobe say her name. Pheobe realises that she would be able to tell if Piper was dead and she couldn't and Leo realises that he and Piper were in the ghostly plane where they did not have their powers.
