Commander Stevenson quotes from Doctor Who

[while examining an infected man who's going to be shot by his comrades] The man is sick, he needs treatment!

Lester

There is no treatment. All we can try to do is stop the infection spreading!

Sorry, gentlemen, I can't allow it.

Commander Stevenson

You can't allow it?

My colleague is a doctor of medicine and I'm a doctor of many things. If we could examine him-

[interrupting him] Commander, I'm afraid we have to kill these people, too. They brought the plague in here.

Who's the homicidal maniac?

Have you noticed these rather strange scratches, Commander?

Commander Stevenson

Can’t say that I have.

All over the ship. I’ve seen them somewhere before, if only I could remember where.

Commander Stevenson

Is it important?

Everything’s important. Well well well.

Commander Stevenson

What is it?

Commander Stevenson

Commander Stevenson

Go on.

It removes tape from radio logs. It must be a very literate and inquisitive virus.

I smell a rat. [The Doctor exits]

Commander Stevenson

[to Sarah Jane] You know, I sometimes wonder if your friend is quite right in the head.

Sarah Jane

If the Doctor scented a rat, Commander, he'll find one.
