A/N: Special thanks to Trulzxoxo for the lovely comments! :)

"That was so beautiful!" Caroline entered the TARDIS. The Doctor had taken her to a planet full of cherry blossoms, he asked her where did she wanted to go and somehow he ended up mentioning the planet and well… she was completely blown away by the idea.

It was refreshing, going to a planet where there was no danger. He enjoyed spending time with her, watching her embrace her humanity.

She had been practicing with the Doctor, transforming into a vampire controlling her instincts and her powers. They found out that she didn't find him "appetizing" possibly because he wasn't human. She still had to feed though, so the Doctor researched and found an alternate universe where there was an artificial blood beverage, he stock a lot of boxes in the TARDIS.

The Doctor approached the controls ready to take her somewhere else just as he was about to pull the first lever a red light started to blink in the console. "That can't be good" he said looking at it.

"Uh.. Doctor?" Caroline was standing still looking at something, the Doctor didn't pay attention.

"Ok, let's not panic I have everything under control" of course, he was lying.

"Wait.. I know what that light is!" he said snapping his fingers.

"Doctor…" she was still looking at something. "It means we have intruders!" he said cheerfully then of course he realized that was a bad thing.

"DOCTOR!" Caroline demanded his attention. "What? What is it Carol… oh" he saw it, a little small rounded creature, looked actually kind of… cute. The creature looked at them with its big eyes.

"It doesn't look that dangerous" she thought, "maybe it's like a space cat or something" she moved and started approaching the creature, she was close enough to touch it.

"Don't touch it!" the Doctor yelled too late. As soon as she touched it the creature went berserk. Jumping everywhere, making all sorts of noises it was just a matter of time before it started breaking things.

"Sorry!" Caroline looked at him as she took cover.

He moved closer to Caroline, "That's a Nubsi"

"A Nub-what?" she saw the creature make another jump, this time higher and almost bouncing into the ceiling.

"They are rather peaceful creatures, until they come in contact with a different specie" he continued, "there is only one way" he was interrupted by another jump, this time the creature almost hit the console "to stop it" he continued.

"And what would that be?" she asked. "Music" he replied, a loud noise indicated the creature hit something.

"We need anything that has harmony"

"You mean like... a song? Do you have a radio in here" Caroline was getting impatient, maybe she could just try to catch it, after all she was quite fast. But then again she thought that touching it again wouldn't be a clever idea.

"I don't have a radio in here, no" the Doctor looked at the walls of the TARDIS worried. Every time the Nubsi jumped it got faster and way more destructive.

"I know, I can sing! Well not really but hey" he started to mumble a song… of sorts… but the creature instead of calming down just started to make an awful sound. Clearly, it wasn't pleased by his vocals.

"Stop it! You're making it worse" Caroline remembered she used to sing. She only sang in special occasions because when she sang she opened her soul. She was nervous to sing in front of him. She really didn't have a choice.

A/N: The story is coming to an end… Will the Doctor and Caroline part ways or stay together? You'll find out soon. PS. There was a wink on this chapter at another popular vampire show, can you tell what it was? (and for the sake of crossovers, let's pretend he can travel through alternate universes without any consequence).
