The Doctor sighs as he wanders through the hospital until he finds who he's looking for. Staring down into the withered face of one Wilfred Mott, he mutters, "Well, Wilf… you did what I asked; you were fantastic."

"Doctor?" Wilf mumbles, his eyes fluttering open.

He smiles. "Hello again, old friend. This is the… fourth different way you've seen me, am I right?"

"Donna!" Wilf sits bolt upright in his seat. "Is she…? What about–"

"Fine, they're both fine."

Wilf exhales a breath of relief. "It was a bit rocky there in the middle, eh, doctor? Uh… hold on, you're not Donna's doctor…" The old man blinks and looks closer at the twinkling eyes of the unfamiliar figure standing before him. "It can't be… Doctor?"

"Yes, Wilf, it's me… at your service," he says, bowing his head slightly.

"You regenerated after all! When I saw that past you – you know, the you in the leather–"

"I remember that; it was the day I first met you… but I wonder if you remember the night you first met me? You saw me twice, you know?"

"Of course I remember the first night I met you! You disappeared right in front of me, you crazy… Twice, you say?"

The Doctor waits patiently for him to realize. Ah, now he gets it, he thinks as Wilf gasps.

"The… the boy with the bow tie and–" He gestures to the top of his own head as he goes on, "and the hat? That was you, too?"

The Doctor nods. "That was what I looked like after the incident with the Master."

"Oh." Wilf's face falls. "So it's happened again since then? What was it this time? Were you–"

"Wilf, Wilf," the Doctor cajoles, "calm down; it's been a long time. I lived for a few hundred years as 'the boy with the bow tie' before… well, that's beside the point. Trenzalore notwithstanding, I have no regrets. And, as for the time after that, well… there was no way around it. But still, everything's fine.

"I came here to tell you about your great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-great-great- great-great-great-granddaughter."

Wilf's eyes widen comically. "How many 'great's, Doctor?"

"One hundred forty-eight."

"Alright… How far into the future are we talking, here?"

"Three thousand years… give or take about a hundred."

"And you thought it was important for me to know about her… why?"

"Did Donna ever tell you about the time I took her to a planet called the Library?"

"The Library?" Wilf thinks for a moment. "Was that when she got stuck inside a world created by a computer?"

"Yes," the Doctor confirms. "While she was there, she lived an imagined life in which she met a young man by the name of Lee McAvoy, fell in love, got married, and had kids."

"That's… amazing. But what's it got to do with my great-great-three-thousand-years-in-the-future grandchild?"

The Doctor smiles. "Your 'great-great-three-thousand-years-in-the-future grandchild' happens to attend the university that one Lee McAvoy goes to."

"Lee McAv– Lee McAvoy's a real person?!"

"Yes, and he had the same imagined life in the Library that your granddaughter did."

"That's… I can't even… that's…"

"You could say, in a way, that Lee McAvoy was fated to be with Donna Noble."

"But my Donna's here! She's happily married! She's gonna have a son!"

"Yes, and little Geoffrey Sylvester Temple-Noble will grow up and have a son, and he'll grow up and have a son… and on and on for three thousand years until one firstborn Temple-Noble is a daughter: Donna-Jenny Wilfred Temple-Noble."

"Donna… Jenny? Wilfred!? Temple-Noble…" Wilf can't believe what he's hearing.

"That's right; the Lee McAvoy that your granddaughter met in a virtual world on another planet in the distant future will find his happiness in her descendant; the first 'Donna Noble' since the original."

Wilf faints.

The Doctor chuckles, pats the unconscious old man on the head, then walks away.

A few minutes later, Wilfred Mott is shaken awake by a nurse who has come to inform him that he's now a great-grandfather.

"Hello, Gramps," Donna calls from the bed as he steps in the door. She has a blue bundle in her arms and her husband, Shaun, stands at her shoulder.

"Aww, there he is," Wilf gushes as he comes closer, "let me see my great-grandson. Hello there, Geoffrey." He reaches out to tickle the baby's chin.

"Geoffrey?" Donna asks.

"Well, yeah; that's his name, isn't it?" Wilf observes.

"We hadn't decided on a name yet," Shaun comments.

"Oh. I just assumed… I mean he looks like a Geoffrey, and–"

"I like it," Donna says, turning to the baby. "You'll be named Geoffrey, after your granddad."

"Does he have a middle name?" Wilf asks, feeling a bit foolish. The new parents shake their heads.

"Did you have a suggestion for that, as well?" Donna wonders aloud.

Just then, Sylvia bursts into the room. "Where is he? Where's my grandson?"

"Sylvester?" Wilf mumbles so she won't hear.

Donna bursts out laughing. "Oh, Gramps!"

Shaun shakes his head as Sylvia rushes over and scoops the baby into her arms. "Ah, there's the little dear… What's his name?"

"Geoffrey," Shaun replies.

"Geoffrey Sylvester Temple-Noble," Donna adds with a slight giggle.

Wilf smiles as the significance of the middle name is lost on his daughter.

"Hello, Geoffrey Sylvester Temple-Noble. My, that's a mouthful. I think I'll just call you Little Geoffy."

"Aw, Mum, come on… can't you call him something a little less babyish? What about when he grows up? Are you still gonna call him Little Geoffy?"

"Of course! I don't care how old he gets; he'll always be my Little Geoffy."

Wilf shakes his head in spite of himself but doesn't say anything; he alone knows what the future has in store for the name Noble.

A/N: Alright, so I've written a part 3 for At Your Service (which was supposed to have been a one-shot and had since received an unscheduled sequel), so sue me. I did notice, however, that this story has a couple of followers – which is ridiculous, because I had it marked as complete with no intention of continuing it!

...You know what I just realized? For once, a later chapter is longer than its predecessor(s)! You're welcome, readers! ;)

Edit/update: September 15, 2013 – I noticed that I had made a technical error in this chapter by changing the tense of the story from present to past. Oops. I've fixed it now.

Also, one of my friends IRL tried to tell me that I had messed up my own continuity between this story and Donna…Noble?! Just in case any of you got confused: when D-J tells her class that she can trace her ancestry to the Chiswick Nobles of 20th century Earth, that's a direct reference to the episode The Unicorn and the Wasp; and, when she says "Donna Noble" is the most commonly repeated first and last name combination according to Guinness Galactic Records (which is my own futuristic version of the popular, similarly-named brand for record-keeping), that does NOT mean there were other people in her family have been named that – which would be a direct contradiction of the Doctor's statement in this story that D-J W. Temple-Noble is the first "Donna […] Noble" since our Donna – rather, it's insinuating that, while Donna was traveling with the Doctor as his companion, since she was consistently using her real first and last name? Yeah, it's the most commonly repeated… because it was used repeatedly throughout time and space – all for the same person!

P.S. If any of you haven't read my story A Lesson in Shakespeare (ffnet story id 9570146) SPOILER ALERT: there is a blatant connection there! If, as deduced by the Doctor in A Lesson in Shakespeare, Lauren Cooper's maternal grandmother is Donna Noble – and since that story takes place in the year 2050 – it can only be assumed that Lauren Cooper's mother would have to be Geoffrey Sylvester Temple-Noble's little sister. ;D
