Setting: after the events of "The Eleventh Hour"
Eleventh Doctor, Jenny
The steady thrum of the TARDIS console echoed around the room, the Doctor gleefully bouncing about with a massive smile on his face, letting out a whoop of joy as he pulled down yet another lever and sent them spiraling into the Vortex.
His laughter is practically contagious, Jenny thought to herself with an equally massive smile. She moved forwards to join him, but her jubilation was replaced by a wash of pain and confusion as her legs chose that moment to give out, and she pitched forwards.
The Doctor was at her side in a heartsbeat, his hands underneath her arms to steady her while her own hands clutched at his jacket. His face was one of pure concern before it morphed into something else, something similar but not quite the same thing.
"Oh, you poor girl," he said quietly. Jenny blinked. "Look at me, I'm a daft old fool, aren't I? You were hurt but I was the one to regenerate. On top of that you nearly got turned into a smoothie when I crashed the TARDIS, and then you came gallivanting after me while I flounced about like a madman and I didn't even notice. As a father, that was a huge mistake on my part, and I apologize. Now, come here."
He had scooped her up into his arms before she could protest, only managing a yelp as her feet left the floor.
"What- what are you doing?" she asked as he began carefully walking back towards the console, then past it, and then into the labyrinth of corridors had he gone from joy to this seriousness in less that a minute? It seemed surreal, and she was a bit worried.
"You're going to your room," he replied in an upbeat tone. "Time for a nap, daughter mine."
"Dad, I'm-"
"Just listen to me on this, Jen," he said before she could finish. "Doctor's orders." Jenny rolled her eyes, but allowed herself to be carried along. He set her down when they reached a familiar blue door.
"Here we are," he said happily, opening the door for her. Come to think of it, she was getting a bit tired... "Go on, change into something more comfortable."
Not entirely sure what her father was thinking, she stepped into the familiar comforts of her bedroom; dark green walls and blue curtains covering simulated windows that would create sunlight or moonlight if she wanted them to, stacks of books everywhere on every other subject, bed, wardrobe, etc... She gingerly changed into a more comfortable set of clothes and tossed the older ones into a basket in the corner. Shame, she really liked that pair of pants...
Opening the door, she found her father absentmindedly toying with a yo-yo, which he promptly dropped a moment later. Jenny laughed.
"Hush, you," he said, smiling as well as he tweaked her nose. He sat down on her bed in the corner, then patted the mattress next to him. She slowly followed suit.
"How badly do you think you're hurt?" he asked, smiling slipping away into seriousness.
"I'm f-"
The Doctor gave her a pointed look.
"Really, though! I can just sleep it off, I'll be fine!"
"Stop being stubborn!" he groaned. "I'm the only one who's allowed to be stubborn here! Please, Jenny. Let me help you."
There was a long, heavy silence.
"Mostly just bruising," she finally mumbled. "Couple nasty scrapes, probably some cracked ribs."
"There, that wasn't so hard, was it?" her father replied, then sighed when she didn't reply. "Jen." She glanced down. "Jenny, come on, look at me. It's not something to be ashamed about. Everyone gets hurt once in a while, that doesn't make you weak."
"Tactical disadvantage," she replied softly.
"It's generally me against the galaxy, Jen, I'm always at a tactical disadvantage. Now, if you wanted to, you could just sleep this whole mess out and then we can go back to see Amelia-"
"We're going back for her?"
"Of course we are! She's waited long enough, she deserves a trip or three in the TARDIS. And as I was saying, you could just sleep this whole mess out, or we could take Option #2."
"What would that be?"
"See, Jen," he said quietly. "I'm still technically in the first fifteen hours of my regeneration cycle and your DNA is essentially the exact same as mine, which means, since I am incredibly brilliant and just a bit mad, that I can do this." He carefully took her hands in his.
It started as a faint tingle, the lightest of spring breezes weaving through the air, but then it grew to something stronger and Jenny could feel the pure energy coursing through her body, golden light twisting and illuminating the whole room. She felt alive and drained at the same time, and it was magnificent.
A moment later the light faded, and she blearily looked up at her dad.
"Feel better now..." she mumbled, leaning into her father's arms. He chuckled softly and pressed a kiss to her forehead.
"There we go," he murmured.. "All better now, eh?"
Jenny, already asleep, didn't respond. The Doctor carefully eased her onto the bed and gently pulled the blankets up around her, then brushed a few stray locks of hair out of her face.
"Goodnight, Jenny," he whispered, turning out the lights. "Sweet dreams."
