He replayed that memory over and over again in his head, every time he closed his eyes, every minute of every single day. Watching his Rose standing on that cold beach in Norway, his hearts breaking at the sight of tears working their way down her cheeks, tears that shouldn't have been there, tears that he had caused to fall.

'I love you'

'Quite right too... and I suppose.. if it's one last chance to say it.. Rose Tyler..'

As The Doctor opened his eyes, he felt the same sense of loss, the same sense of grief that he had felt that day; each time he remembered that scene, those feelings hit him like a blow to his stomach, leaving him feeling cold and empty.

He remembered how he had wasted his time upon that beach, how he had left both of them stood in silence for so long, too long; and when it had come to confessing his feelings to his Rose, he hesitated, he tried to buy more time, he chickened out, stalling with useless words and pauses.

Every time he replayed that memory, the bitter irony of the situation stung him, he the Oncoming Storm, the last of the mighty race of the Time Lords, had run out of time.
