Also, and I could be wrong, but regarding the title, I believe that a swan song is related to death and the legacy of a person after they've passed. Perhaps there will be a major death in the winter finale (5x10) or in this one. The 10/12 split was an early plan that has since changed, they are now doing 11/11. 512 is now the spring premiere and 100th episode. Adam confirmed that.
