"Tell me why we're doing this again?"

He stopped short, nearly taking her down in the process. His hands shot out immediately even though she had already gotten her balance back.

"You don't have to, Donna," he tried to explain, "This is something I want to do."

"Whither thou goest, I will go," she quipped as they walked down the street.

The Doctor rolled his eyes, "As if you would ever be so subservient…"

She beamed back at him, he knew her so well. They kept walking towards Millennium Center, enjoying the quiet of the morning.

She turned to him, "What exactly are you going to do once we get there?"

He flashed her a mischievous grin and waggled his eyebrows.

She put up a hand, "Wait, don't tell me. I really don't want to know."

He laughed and wrapped an arm around her as they walked. There was a silence before he spoke.

"I want to try and give him hope Donna."

She looked confused, "Who?"

He stopped and she with him.

"Jack. I want to try and give Jack hope."

They started walking again and this time it was she that broke the silence.

"How can you give him hope?"

The Doctor smiled, "By telling him about you."

He pulled her a little tighter in.

"About us."

He gently kissed her temple.

"About all of us."

He looked out to the horizon, "Jack and I are very similar, Donna. He lives forever, I live, well, I might as well live forever. We both have the privilege of seeing the entire galaxy and the torture of seeing people we care about pass on. I never thought I'd have a family again. Neither of us did. Maybe this can help him somehow."

He shrugged, "But you never know with Jack."

They continued their walk until he motioned her onto the invisible entrance. They stood hand in hand as they descended into the Hub.
