Before Tom's death on The Blacklist, he questioned Red about that infamous bag of bones. Red told Tom that the contents of the duffel bag are a "secret, not a lie." That single line may be the most telling clue Red offers about the bones and their implications. As of the end of Season 5, Liz has learned the truth: that the bones belong to Raymond Reddington, but not the alive and well man played by James Spader we've come to know over the past five season. Liz now believes the man she knew as Red to be an imposter, and all signs seemed to point toward this as the truth. But is he really an imposter?
