Along with Castiel came other angelic characters, with Robert Wisdom portraying the "militant" and "dogmatic" Uriel, who secretly supports Lucifer; Julie McNiven playing the fallen angel Anna Milton, who eventually regains her angelic form but remains an outcast of Heaven; and Kurt Fuller as Castiel's boss Zachariah, who wishes to start the Apocalypse in order to bring Paradise to Earth. Though Wisdom's character is eventually killed, McNiven and Fuller continue their roles into the fifth season and are joined by Mark Pellegrino as the recently released but fallen archangel Lucifer. Pellegrino also appears as Lucifer as a hallucination in Sam's head in season 7. Pellegrino had been the second choice for the role of Castiel and was offered the role of Lucifer without an audition. Further on, Fuller's and McNiven's characters were also killed along with both Harvelle characters.
