"And you go with him, that wonderful Doctor. You go and see the stars...and then bring a bit of 'em back for your old Gramps."

That's what he'd said, and now it was time, she knew this day would come eventually and she knew she'd have to face it, now was the right time.

"Doctor, I want to go see my Gramps, on his deathbed, would you mind?" She asked, even though she knew he wouldn't mind.

"Of course, if you're sure you're ready. Do you want to go now then?" He asked, worried that she wasn't prepared for this just yet, but she nodded enthusiastically and smiled at him. "Okay then, allons-y!"

He started running around the console, pulling different levers, pressing different buttons and saying different things. The TARDIS began to shake, and when it came to a sudden stop and she knew they had arrived, so she made her way slowly to the door, with a gift-wrapped box in her hand. They walked up to her front door and he took a hold of her hand, raising his other one to push the doorbell.

Sylvia answered it, and her hand covered her mouth in shock, she hugged Donna tightly and pulled her inside. She'd already started talking at a ripping speed, assuming this was just another drop-in visit, as soon as there was a gap Donna interrupted.

"Mum look, it's great to see you and everything and I really want to catch up but...I need to see Gramps first. Is he in his room?" Donna asked, her mother nodded, understanding immediately. Donna quickly walked out of the room, and started up the stairs, leaving the Doctor alone in the front room with Sylvia. She reached the bedroom door and knocked softly, when she heard a quick reply she opened the door and walked in.

The happiness in Wilf's expression was undeniable, the joy of seeing her again, the relief she had come back to see him one last time. He stretched out his arms to her, and called her over in a weak voice.

"Hey there Gramps, how are you doing, ey?" She leant in for a quick hug and gave him a light peck on the cheek before sitting down on the chair next to the bed in which he was laid. Holding out the small present in her hand and he raised his hand to take it, she placed it in his grasp and smiled, ushering him to open it. When he had discarded the wrapping and pulled the lid off the box, he looked at the contents and frowned confusedly.

"What's this sweet'art?" He picked out the small rock, it was a beautiful purplish colour with flecks of gold in it, still not knowing exactly what it was. She smiled back at him, obviously forgetting their last conversation.

"Last time I saw you, you said I should go and bring back a bit of the stars for you, well not exactly, but near enough. That," She said, nodding toward the small cluster in his hand. "is a rock from a planet called Violamonda, it's 47 billion light years east of here, and the ground is made purely of amethyst but just beneath the surface there are clusters of diamond and gold. If you sold this on Earth, it'd probably fetch you about a billion quid, around about."

Wilf was crying silently, and he looked mesmerized by the rock in his hands, he was twirling it round, watching it sparkle under the light. "Beautiful." was all he could say, but it was more than enough.

They spent hours, talking about all the places Donna had been to, all the things she had seen and done. They cried, and reminisced, and smiled and laughed, and both of them felt happy.

"Thank you." Donna said, Wilfred frowned not really knowing what Donna was thanking him for, and on seeing his confusion she smiled. "For telling me all those stories when I was young, for making me believe in aliens and everything else like that. Thank you Gramps for being the stargazer that I love so much."

"No need to thank me for that love, just make sure it's worth it. You're having a good time out there aren't you?" Wilfred asked, already knowing the answer, just wanting to hear her say it again.

"The best Gramps, really it's the best." He smiled at her, and she smiled back, and he drifted away quietly.
