Sorry not sorry for this choice. Found out Billie Piper used to be a pop star in the 90s, watched the video for "Day and Night", and, well, how could I not use that in this fic?

Chapter Five
Day and Night

The Doctor's finger hovered over the Pause button when the chords to the next song, a 90s pop one from the sound of it, started.

Then the vocals kicked in, and he started.

All of the day, all of the night
You do the things that make me feel so right.
My shining star, my guiding light
(My shining light).
And that's the day and night, babe.

That almost sounds like . . . he thought. No, it can't be Rose. Since when is she a pop star?

It just ain't the same when you're away.
You are my inspiration.
I'm hanging on to every word you say,
Cos you are my motivation.
You make me feel so right
Every day and night.

He quickly checked the artist, and his eyes widened. Her name was Billie Piper, but her image . . . she looked identical to Rose.

Unless that was Rose's stage name?

If he thought about that too much, he'd get a headache.

Besides, this song almost seemed like . . . No.

Was it about him?

Cos the only time I think of you
Is every day and all night through.
Whenever I breathe you're on my mind
Every day and night, babe.

All of the day, all of the night
You do the things that make me feel so right.
My shining star, my guiding light
(My shining light).
And that's the day and night, babe.

He didn't really have that effect on her, did he? Yeah, he did, if this song, "Magic Man," and "Bad Case of Lovin' You (Doctor, Doctor)" were anything to go by.

I need you tonight, but you're not around
I need to hear your voice, baby.
Something feels strange; there's not a single sound.
I wish you were at my door, babe.
You make me feel so right
Every day and night.

Cos the only time I think of you
Is every day and all night through
Whenever I breathe you're on my mind.
Every day and night, babe.

All of the day, all of the night
You do the things that make me feel so right.
My shining star, my guiding light
(My shining light).
And that's the day and night, babe.

As long as he was being honest, he cared about her in a way that was more than friendly. He'd been lost from the moment he grabbed her hand and whispered, "Run." He'd even given up his ninth life to save her . . . and he'd done it by kissing her, something he'd wanted to do from the moment she saved him from the Nestene Consciousness.

Or was it before then?

Not that it mattered right now.

Gotta let me know, oh yeah,
When you're coming home
(When you're coming home).
You know you make me feel so right
Every day and night.

Cos the only time I think of you
Is every day and all night through.
Whenever I breathe, you're on my mind.
Every day and night, babe.

All of the day, all of the night
You do the things that make me feel so right.
My shining star, my guiding light
(My shining light).
And that's the day and night, babe.

Oh, who am I kidding? Course it matters. He frowned. If my people found out about this, were they still alive . . .

The Doctor gradually realized he was humming the chorus. He couldn't help it: It was that catchy!

A thought occurred to him, and he smirked. Oh, he would have so much blackmail material on Rose. This could actually be quite useful.

Mind you, he had no idea what he would do if she randomly burst out singing in the console room. Especially if it was one of her own songs.
