 PLOT: When telling the story about the Sleeper, it was said and  shown that he had bitten his tongue when he was a child. At the end  of the movie he is speaking without any problems, which is  impossible without a tongue. The same things happens with Peter, who  also bit off his tongue when he was possessed by the Sleeper. Later  in the movie, when he is lying on the floor, dying, he speaks  normally.
