THE END IS THE BEGINNING
This is the most important sequence in the whole story of Battlestar Galactica. If the cycles of time repeat then the end must be the beginning. The story began with Six and it should end with her. In the miniseries we were left with a great mystery: who was the person she was meeting (that we did not see) after she met up with Baltar? Most likely this person is the fifth and Final Cylon. Roslin will have a memory flashback or a dream at the same place, where she is crying/laughing in the fountain ... is this after her cancer diagnosis? In a dream/hallucination where she realizes something profound by returning to this place?
