Hello! Apologies it's taken me so long to update – I was really stuck on what to write, but I got there! I hope you enjoy it and if you've got any ideas or suggestions, don't hesitate to share them :p Anyway, enjoy! :)

The TARDIS landed with a slight jolt. Chloe looked at the Doctor, who grinned at her and pulled the scanner towards him. "Well, we've landed," he said as he watched the symbols on the screen. "Have we landed in the right place?" River asked teasingly, "You're well known for not getting to where you want to."
The Doctor looked at her," Yes, we've landed in the right place. Right time as well."
"Well done, Chloe," River praised.
"Oi! If it wasn't for me, she wouldn't have known how to do it!"
"You know full well that the TARDIS would teach her!"
Chloe laughed as the Doctor pulled a face at his wife. He turned round to Chloe. "Go on. Get it set up. We'll be there in a minute or two."
Chloe nodded and took the bottle of fizzy drink out of its container, as well as the Mentos. The Doctor and River glared at Jack. "I'll go help her," he said, understanding what they were trying to get across.
He went over to Chloe, who argued that she was fine on her own. He helped her anyway, whilst she kept insisting she could cope. The other two watched them with a smile. As Jack shut the TARDIS doors, River turned to the Doctor. "Why are you being like this?" She asked, arms crossed.
"Like what?"
"You seem rather fatherly to her."
"If you haven't noticed, River, her parents died and she's a Time Lord. Plus, we're sort of family."
"Family? How?"
"Well, in my incarnation before this one, my hand got cut off and I grew another one. Then my friend, Donna, touched it, creating a Metacrisis who I sent to the parallel universe where he married Rose and they had a baby who became Chloe. As the Metacrisis had my DNA but also a bit of Donna's, it means I'm sort of Chloe's grandfather."
"So I'm sort of related to her?"
"Yes, I suppose you're then her step-grandmother. Or grandmother or whatever, I dunno. Up to you, but we are family, and I will look out for her, just like her mother asked me to."
"You still don't have to be so excited."
"What else am I meant to be then? Miserable? If you haven't noticed, she's not had much of a childhood, and I need a distraction. So, if you'll excuse me, River, I'm going to have some fun." With that, he went outside of the TARDIS. River let out a sigh before following him.

"Right!" The Doctor exclaimed, clapping his hands together as he stepped out. Chloe turned to him and gave him a smile. "We're almost done," she said as Jack fidgeted with the bottle and the Mentos. "Good!" He praised, "Though I don't think it needs that long to set up."
Chloe shrugged and smiled as River came out.
"We'll have to stand back," Jack warned, "I've watched videos about things like this and it can cause a big reaction."
"Not bad I hope," the Doctor said.
"No, nothing like that. Right! Ready?"
The Doctor happily said yes, as Chloe frowned at something. "Chloe, what's wrong?"
"Doctor, the TARDIS," she replied, pointing behind them.
The others turned to the TARDIS and saw it was in the middle of vanishing. "No, no, no, no, no!" The Doctor shouted, and brushed a hand through his hair. "Oh, that's just brilliant, isn't it?"
"What happened?" River and Jack asked at the same time.
Chloe walked to where the TARDIS was and sniffed. "Doctor, can you smell that?"
The Doctor also casually sniffed and instantly pulled a face. "Oh! Yes. Teleport. Nasty. Short range though, so whatever took the TARDIS-"
"Is nearby," Chloe finished.
