Changes

Chuck begins his final book, titled "Swan Song", with an explanation of the Impala's history and significance. He is later called by Dean for the location of [[Lucifer]] and [[Michael]]'s final battle, which he readily gives. He finally appears dressed in white, musing on the difficulty of getting endings right. He then disappears - Chuck, it seemsleading viewers to believe he may, is in fact, be [[God]].
