Over a thousand years he had been alive and yet it didn't make what was about to come next any easier.<br/><br/>So many lives had been sacrificed in his name, so many families had been destroyed, and it was all his fault. The trail of heartbroken parents and lonely children was far too long. And now, he was about to add to it.<br/><br/>Painfully slowly, the Doctor stepped out of the TARDIS and looked out at the family with a look of absolute remorse on his face.<br/><br/>"Mr and Mrs Baker...I'm sorry," he spoke softly, his eyes lowering to the ground. "I am so, so sorry."
