the thing with the other thing

30 Day Doctor Who Challenge: Your Favorite Companion

The answer to this question has gone through a lot of phases before settling on Donna. I started listing them all out but really, it doesn’t matter, because Donna.

Donna is much more grounded than any of the other companions. She doesn’t take any of his shit. She doesn’t believe things just because he tells her. She has to see for herself, investigate on her own.

Donna: Tell me where I am. I demand you tell me, right now, where am I?
The Doctor: Inside the TARDIS.
Donna: What?
The Doctor: The TARDIS.
Donna: What?
The Doctor: The TARDIS!
Donna: The what?
The Doctor: It’s called the TARDIS!
Donna: That’s not even a proper word. You’re just saying things!

Along with that, she’s ridiculously, constantly curious. She thinks up questions even the Doctor hasn’t thought about. In all 900+ years, she’s asking new questions within days. And it annoys the Doctor, he gets irritable, because he knows that he’ll never see the world the same way she does. That, in some ways, she’s a lot smarter than he is.

Donna: What if I said something in actual Latin? Like “Veni, vidi, vici.” My Dad said that when he came back from football. If I said “veni, vidi, vici” to that lot, what would it sound like?
The Doctor: I’m not sure. You have to think of difficult questions, don’t you?
Donna: I’m gonna try it.
Seller: Afternoon, sweetheart. What can I get you, my love?
Donna: Um, veni, vidi, vici.
Seller: Huh? Sorry? Me no speak Celtic. No can do, missy.
Donna: Yeah. What does he mean, ‘Celtic’?
The Doctor: Welsh. You sound Welsh. There we are. Learned something.

Donna never gives up. None of the companions do, not really, but while Rose looks into the Vortex and Martha spends a year walking the Earth on a Capital-M Mission, both of them had to change first. Martha became a soldier. Rose was her stubborn self, but she still used a power outside herself. Donna?

Wilfred: You’re not gonna make the world any better by shouting at it!
Donna: I can try.

After Martha, the Doctor gives up on companions. He’s too proud and he’s too scared that he’ll hurt someone again. He’s stubborn, too, always, about everything. Donna changes his mind.

The Doctor: I don’t need anyone.
Donna: Yes you do. Because sometimes you need someone to stop you.

The Doctor: You were right. Sometimes I need someone. Welcome aboard.
Donna: Yeah.

What’s more, though she’ll never know (*sobs*), after a single episode, just part of a day, she’s exactly right about why he needs someone. When she’s gone, he falls apart. He becomes the Time Lord Victorious. Wanna bet Donna wouldn’t have let that happen?

Out of all the companions, Donna made the biggest impact on the universe. I can’t even talk about Planet of the Ood without bursting into tears, but the Ood are my favorite species in the Whoverse, and they see.

Ood Sigma: And know this, Doctor Donna. You will never be forgotten. Our children will sing of the Doctor Donna. And our children’s children. And the wind and the ice and the snow will carry your names forever.

Also?

Also Donna’s hilarious.

Not only hilarious, but when she thinks she’s the Doctor is getting up in her business, she backs up into his own spaceship. If he did want to “mate” with her, she was going to close the door, lock it, and fly away with the TARDIS.

I mean.

Come on.

No competition.
