They watched a couple of Harry Potter movies before going to sleep. By that time Lena was quite toasty and eagerly wishing for the next day to come so that they could go on another adventure—hopefully this time more successful on her end. But the other two informed her that after a day like the one they'd just had, they usually took the next day off to just relax on the Tardis.

"Want to go swimming with me tomorrow?" Rose asked.

"Sure! I haven't gotten to swim for a while, since it's the middle of winter. Was the middle of winter. Whatever."

"And we can make banana waffles for breakfast!" the Doctor said brightly. "And banana smoothies."

"I want strawberry," Lena said. The Doctor made a face.

"But that's boring. Bananas are better."

"Not for my smoothies," Lena insisted. "I want strawberry, and that's final."

"Me too, actually," Rose said.

"Fine," the Doctor sighed dramatically. "You win."

"Hey Doctor?" Lena said as they were leaving to head to their own rooms.

"Yeah?"

"Can I decorate my room?"

"'Course. Not tonight—we all need to go to bed. But tomorrow you can work on it. And I bet the Tardis'll give you a computer and iPod and all that if you ask nicely."

"Awesome!"

"Night, Lena," the Doctor said before turning off the lights.

"Night, Doctor. Night, Rose," Lena called back as she snuggled under the covers, hugging the teddy bear the Tardis had so nicely provided for her.

"Night," Rose replied as they closed the door.

Lena lay quiet for a while, but after a while she still couldn't sleep. She had too many questions running through her head.

"Tardis?" she said, rolling over to look at the dim ceiling above her. "Sorry. I don't know what I'm doing. I'm just wondering about how you really communicate...'cause, you know, in the show the Doctor says you're telepathic and all that, but he never goes into detail about what that means. And then in tons of the fanfictions you talk to the companions and the Doctor just like a regular person. And you just generally seem more alive—flashing lights, humming, moving things around. Those things were hinted at in the show, but never really shown. I can't help wondering what's true and what's made up." She paused and shook her head. "Look at me, talking to a sentient spaceship. I feel ridiculous."

Oh, you're not ridiculous at all. I find you quite nice to listen to.

Lena fell out of the bed.

"Oh my gosh," she choked out. "Oh you sexy girl, you. I always hoped it was true. You really do talk to people!"

Well, obviously.

"Sorry, I just thought maybe it was only the Doctor you could speak with, and maybe only through feelings and such. I didn't know you could talk to anyone."

I'm always able to. I simply don't often choose to. You're special in that regard.

"And Rose?"

The Doctor knows I speak with her sometimes. But Rose and I share a special connection. She looked straight into my very heart, and no one else has ever done that or ever will.

"She's Bad Wolf." The lights dimmed for a second, and a chill swept through the room momentarily.

Names have power, Lena Siteman, the Tardis said gravely. You should remember that. Bad Wolf is not a name to be thrown about casually. It has the power to raise up races and topple empires, bring the dead back to life and commit total genocide. It is not wise to mention Bad Wolf unless absolutely necessary.

"I'm sorry," Lena said, chastised.

Don't feel bad, my firefly. I just needed to teach you that names are important and dangerous things now so you don't make a terrible mistake in the past. I mean future. Sorry. Tenses are difficult...

Lena laughed. "I know. You said so before."

Did I? Oh, you mean when I'm in that tiny little person body with the raggedy dress and there's the next Doctor on the planet that isn't a planet, that evil thing that eats Tardises. And the biting! I like biting. It's like kissing—

"Only there's a winner," Lena finished. She laughed. "Can we make my room cool?"

When you wake, firefly.

"Why do you call me firefly?"

Spoilers, sweetie.

"I really hate that word."

Not as much as the Doctor.

"True. Can I have a laptop and an iPod, too?"

Of course. And a cell phone, for safety when you're out. Best to be able to stay in touch with Rose and the Doctor. And I have the whole internet from your universe saved, so you can still have all your old files and music and whatnot. Plus you'll be able to finish all those fanfictions you love reading so much, the Tardis said, teasingly.

"Oi! I don't need them that badly. I could live without them if necessary. But...only if absolutely necessary. I really, really love fanfiction." Lena sighed. "Okay, you're right. I need those fanfictions. Hi, my name is Lena, and I'm a fanficaholic." The Tardis laughed. "Thanks so much for everything. It's going to be awesome having my own stories and poems and music again. I miss my iPod."

I know. You'll get one tomorrow. But for now, it's time for you to sleep. Rose has gone to bed, and so has the Doctor, surprisingly; he doesn't often sleep. But then, he has had a draining last few days. Sleep, Lena. Don't worry about anything. Just sleep. And when you wake up, I'll be waiting to set up your room.

Soft instrumental music began wafting around the room as Lena closed her eyes.

"Good night...Idris," Lena whispered.

Mmm. I always have liked that name. Goodnight, little one. Sleep well.

That night, Lena slept better than she ever had before. The Tardis watched over her three sleeping passengers, just as she always did.

Hi everyone! Sorry this took a while. Life was insane and then I uploaded the wrong chapter when I was using my friend's computer and yeah. But hopefully I'll get the next chapter up sooner—you're going to like it. ;) Thanks for reading and all your lovely reviews, favorites, and follows! You guys are the best. Stay awesome!
