Time has a habit of bringing us back to that place we think we have left behind forever.

The Doctor, especially in his tenth incarnation, has lived through the emotional turmoil of losing companions, his people, and at times, his own perspective on the Universe; pushed through time and sometimes not able to withstand the pressure facing him from all sides. He might win, he might save the day, but it feels like a loss, a devastating failure in which his actions to save Gallifrey in a previous life still echo around him like marbles in a tin can.
