Unless we work very closely together, we could be here until the crack of doom. Oh, what's the use? Can I have one of your pickles? I had a rushed lunch.
S18 E5Warriors' Gate
One good solid hope's worth a cart-load of certainties.
Will Romana be all right?
All right? She'll be superb!
You were the noblest Romana of them all!
He's mad, the backblast backlash will bounce back and destroy everything.
[The Doctor goes to rescue Biroc's Race]
If I'm not back in thirteen and a half minutes, dematerialize.
Without you?!
I am not letting you go out there alone!
That's an order. It's time you started accepting orders.
It's long past time but how are you going to find it?
With my eyes
Adric and I have seen it
Right. Come on then.
I'm coming too
You are not, it's long past time you obeyed order. Now stay here, and if we're not back in thirteen and a half minutes, I want you to dematerialize. Is that understood?
I like that. You're improving.

Run Doctor! Scurry off back to your blue box. You're like all the rest: lizards when there's a man's work to be done. I'm sick of your kind. Faint-hearted, do-nothing, lily-livered deadweights. This is the end for all of you. I'm finally getting something done!
S18 E6The Keeper of Traken
I don't see what the law of probability has to do with it.
No. [realizing what Adric said] What?! Adric, I've given you a privileged insight into the mystery of time, yes?
Yes.
Introduced you to adventures beyond imagining, yes?
Yes.
And you criticise my logic?
No, no, I'm just saying that a lot of the time you don't really make sense.
[pauses] Ah! Ah, you've noticed that, have you? Well, anybody can make sense.
Adric, if I knew everything that was going to happen, where would the fun be?
Traken Union, famous for its harmony. A whole empire held together by- by people being terribly nice to each other.
Well, that makes a change.
They say the atmosphere there was so full of goodness that evil just shrivelled up and died. Maybe that's why I never went there.
[about the Keeper disappearing] What do you make of it?
I don't know. But I do hope we know what we're doing.
Yes, so do I. [realizing what Adric just said] We?!
[points at the Doctor] You. [the Doctor smiles]
What can't be cured must be endured.
That's the silliest thing I ever heard.
Oh don't listen to me. I never do.
Oh by the way, by the way! Neeman, Neeman come here! [puts his arms around the guards] You chaps might be interested in this as well. Listen. Do you know that expression, uh, two heads are better than one, hm? [knocks the two guards' heads into Neeman's head, all three of which promptly collapse] Well I think that one head is better than three!
A new body, at last!
