Donna stopped adventuring when she turned five months pregnant and it became so noticeable that aliens started kidnapping her more often. By this point Donna had become so sick of evil villains threatening the Doctor with the death of his "wife and child" it didn't take much persuasion at first for the Doctor to talk her into staying aboard the TARDIS while he went off to save the innocent.
But God did she come to hate it, as it was often boring for her just sitting around, and (although she would never willing admit it) she was terrified that the Doctor wouldn't cope without her, and she couldn't bear the thought of him getting hurt or... well, worse.
The Doctor made an effort however to make sure she still got see the Universe, taking her to safe, but beautiful, places, and taking her back to the TARDIS whenever danger came lurking out of the ever present shadows, but Donna still found it annoying and frustrating to sit by idly while the Doctor was risking his neck alone.
"I'm an adrenaline junkie!" She insisted for the seventh time that hour. "This entire 'tip toeing around danger' business is starting to get on my nerves!"
But Donna knew it was for the best, and eventually stopped arguing, reminding herself it was best for her baby. If she went out, and something happened... she would never be able to live with herself.
Eventually on these occasions when she sat in the TARDIS waiting patiently for the Doctor to return and awe her with a blow-by-blow account of events which she always amusingly interrupted with her own versions of what probably actually happened, to the Doctor's annoyance.
On one such occasion, her thoughts began bringing back doubts about the Doctor's promise for the TARDIS to always be home to her and the baby.
She tried not to think about it, but the thoughts continued to haunt her. The Doctor had insisted it could stay aboard as they adventured, and the TARDIS would take care of the baby (a strange concept, as apparently Time Lords used TARDIS' as baby sitting services all the time when they were alive), but still the same nightmare came to plague her. A baby crying for its mother... for anyone really, anyone at all, as the Doctor and Donna both fell in battle, too far away to hear its cries...
"When you going to tell your Mother and Grandfather?" The Doctor asked, interrupting her thoughts as he waltzed in after saving the entire population of Clom from a race of angry horse sized rodents led by a fanatic scientist.
Donna jerked, and began to tap her fingers on the edge of the TARDIS monitor irritably, on which she'd been watching the Doctor save Clom, a recent idea of the Doctor's to keep her from getting bored and feeling out of it.
"Good to see you too!" She huffed. "Nice work with that scrawny git by the way, just as well I wasn't there. I would've slapped him so hard you'd be having nightmares for weeks!"
The Doctor winced. "I already do Donna, I already do." He assured her, before pressing on quickly. "Doesn't answer my question though, when are we telling
Sylvia and Wilf?"
Donna sighed, there was no escaping it. It had been at the back of her mind for a while now, and it would be better to do it now than turn up with, say, a five year kid on their doorstep in the distant future.
"The sooner the better I suppose." Donna said. "But what am I supposed to say? Hi Mum, guess what? You're going to be a grandmother, and oh, by the way, it's the result of a one night stand with an American immortal that lives in Cardiff fighting aliens every other day!"
The Doctor winced.
"Don't take it out on me, it's not my fault!" He insisted.
Donna smiled.
"Maybe I should just say you're the father, and we're going to get married, eh Space-Man? THEN it will be your fault!"
"No thanks, if your slaps are anything to go by I don't want to have to deal with your mother's!" The Doctor then paused. "On the other hand, if you tell Jack..."
"Yes, of course." Donna cut in sarcastically. "I can tell Jack, and then we can tell my family together, and then we can get married, and have more ginger babies and live happily ever after..." She turned serious. "No, it's not going to happen."
"I know Jack!" The Doctor insisted. "He wouldn't... Wait. Ginger babies? Will EVERYONE be ginger except me?! That's not fair!!" The Doctor shook his head quickly to clear his thoughts. "Anyway, as I was saying, I KNOW Jack! He wouldn't…"
"Yeah, well, I DON'T know Jack, and I'm not taking your word for it!" Donna snapped.
Five long months had passed, and that first month had been absolute hell coming to a decision, nearly ending with her terminating the baby! In that time she'd come to forget the Jack she'd spoken to, and come to love in just one day, and her fears had twisted her memory in so many directions and possibilities, until at last she'd made Jack into something he wasn't.
After all, she'd loved Lance. Loved him with all her heart, and thought the sun shone out of his glorious backside... and he'd turned out to be using her all along. Somewhere deep, deep down, she thought Jack was doing the same.
And she wasn't letting him near her baby. She didn't want him to know.
"So am I taking you to your Mum's or not?" The Doctor asked, slightly exasperated. "I'll be with you the whole time." He added, offering her his hand with a grin.
Donna thought long and hard for a moment, and then sighed, taking his hand reluctantly.
"I guess the truth will have to do." Donna said. "They're going to try to talk me into staying home though, at the very least."
"That's for you to decide." He promised. "Not them, not me… You." The Doctor reassured her, and pushed down a few levers.
In five minutes, Donna stood outside her old home preparing herself to walk in. The Doctor however, not noticing Donna's glare, went ahead and pressed the doorbell.
"They're not in, let's go." She turned round and began walking down the path.
"Donna," The Doctor pulled her back swiftly, so quickly Donna veered too far to the side, but he caught her just in time so she wouldn't fall and hurt the baby.
That's when her grandfather opened the door, and was startled to see Donna in what he assumed was a passionate embrace.
"It's not what it looks like." Donna yelped, shoving the Doctor off.
"I never said a word!" Wilf pointed out, but he smiled and winked at the Doctor all the same, making the pair go bright red, especially bearing in mind the news Donna was bringing.
Donna shook her head clear of thoughts about her pregnancy and beamed at her Grandfather.
"Granddad!" Donna said genuinely happy to see him and, forgetting entirely about her pregnancy bulge, hugged him tightly.
"Any more adventures to tell your old Granddad about eh? OH, did you go to Barcelona after all? The planet I mean, not the city..." Wilf beamed like a young boy at Christmas. "Oh come in, come in!" He ushered them both in and closed the door.
"I've erm, got something to tell you and Mum..." Donna said, as Sylvia peered round the corner.
"Typical; gaining weight on holiday." She said. "I'd lose it if I were you though, you look pregnant."
Donna went bright red again, and the Doctor scratched his head. Wilf and Sylvia's eyes widened.
Sylvia went mental.
"Pregnant?! Pregnant?!?!" She screeched. "What the hell have you done this time?"
"I'm not sixteen Mum, I can do as I like!" Donna yelled angrily, crossing her arms. "And if I want this baby, I'm having this baby!"
A moment passed in silence, with the pair staring each other off.
"I guess not." Sylvia eventually decided. "But unmarried?! What would your father say...?"
"He'd be proud of me." Donna said stubbornly. "And he'd be excited that he was going to be a grandfather!"
As Sylvia struggled to think of a comeback, Wilf gawked at the Doctor, before it turned into a frown.
"I told you to protect her! And you go and get her..."
"He's not the father." Donna said bluntly. "He had nothing to do with it Granddad" Donna then went on reluctantly. "The father doesn't know, and I don't WANT him to know."
"Not yet anyway." The Doctor added, and then grinned at Wilf. "So, great grandfather, quite an achievement eh Wilf?"
Wilf hesitated, letting it sink in, then beamed and kissed Donna's cheek.
"Congratulations love."
"Thanks, Granddad."
"Well come-on through then." Sylvia said. "Eastenders is on."
Donna rolled her eyes. Typical Mum, not even a five month pregnant daughter would get in the way of Eastenders! But Donna loved Eastenders too, so she pulled the Doctor into the living room to watch it too, thankful her mother wasn't raging at her and belittling her like she'd been worried she would.
There on the screen, was Tiffany Dean at the teeny weeny contest, singing and dancing to Fire starter by the Prodigy. Everyone in the Vic was cheering, and quickly Donna, Sylvia, and Wilf were too, even the Doctor, who'd stopped watching it after Danielle died.
"Aw bless, she's just like a miniature Bianca!" Sylvia said. "You used to be like her you know, flaming red hair and all, nasty temper to go with it I suppose but..."
"Mum! You're brilliant!" Donna said, over the moon. "Tiffany! I'll call her Tiffany!"
"It's a girl?!" Sylvia asked, completely gob smacked. "Oh sweetheart that's... that's wonderful..."
Donna stared at Sylvia like she'd never seen her before in her life. She hadn't called her sweetheart since her father had died, and even before then it had been rare, the last time she'd said it having been before walking up the aisle to Lance.
"Actually Mum, I don't know." Donna admitted. "I want it to be a surprise, but I've already got a name picked out if it's a boy, and now I've got Tiffany if it's a girl."
"Really? What will you call it if it's a boy then?" The Doctor asked curiously.
"Geoffrey Jack Noble."
"Jack?"
Donna glowered at him.
"I've had this name picked out a while I'll have you know, 'God-Father', and..."
"God-Father?!" The Doctor repeated, gob-smacked. "You want me to be...?"
"Yes!" Donna said with a laugh. "'Course! Who else would I have? That Owen twat? 'Space-Man' was getting old anyway..."
"Well that's... that's..." The Doctor was lost for words. "That's brilliant! God-Father? Absolutely brilliant!"
"Your father would be overwhelmed to hear you name his grandson after him." Sylvia said.
For a moment mother and daughter shared a look of understanding between them, a moment they hadn't shared in a long, long time, before a red faced Sylvia turned to the telly again and began bad-mouthing Ian for his greedy trick in the contest.
"Got a middle name for little Tiffany yet?" The Doctor asked, after glancing at Sylvia with some confusion; human domestics could be fairly confusing, he decided…
Donna glanced at the Doctor nervously.
"I've got an idea, but... I dunno..."
"Come on, I want to hear it!" The Doctor whined, and Donna gave in.
"Tiffany Rose Noble." She said quickly.
"That's beautiful sweetheart." Wilf said, patting her bump gently. "Tiffany Rose Noble, what a lovely name. A beautiful name for a beautiful girl, if it is a girl that is."
"Tiffany Sylvia Noble would be better." Sylvia cut in, half-way through her Ian Beale rant. "Or does my name not make the list?"
"Tiffany Sylvia Rose Noble then!" Donna snapped. "Happy?" She then glanced at the Doctor, and realised he was being quiet, far too quiet. "Doctor?" She asked, concerned. She should've realised it wouldn't be a good idea to use Rose, not when the friend he'd lost had been called Rose.
"It's good, a good middle name." He finally said, with a cough, and then he added under his breath. "Tiffany Rose Harkness has a better ring to it thou- ouch!"
Donna had smacked him round the back of his head.
"Shut it Space-Man or I'll shut it for you!" She threatened.
The Doctor winced.
"Back to Space-Man? Does this mean I won't be God-Father anymore?" He whined.
"Depends on whether you can keep your mouth shut or not doesn't it Doctor?" Donna huffed.
The Doctor nursed his head as Donna rolled her eyes and sat back relaxed. All was well in the Noble household, and it was comforting to know that her family would be there to support her through this without asking pesky questions like one certain Time Lord.
"So... about the father... This 'Harkness' I take it..." Wilf began.
On the other hand, maybe not.
