Time Lord and The Doctor in “Genesis of the Daleks”

Ah, welcome, Doctor.

What's going on? Don't you realize how dangerous it is to intercept a transmat beam?

Oh come, Doctor, not with our techniques. We Time Lords transcended such simple mechanical devices when the universe was less than half its present size.

Look, whatever I've done for you in the past, I've more than made up for. I will not tolerate this continual interference in my life.

Continual? We pride ourselves we seldom interfere in the affairs of others.

Except mine.

You, Doctor, are a special case. You enjoy the freedom we allow you. In return, occasionally, not continually, we ask you to do something for us.

I won't do it. Whatever it is, I refuse.

Daleks.

[interested] Daleks? Tell me more.

We foresee a time when they will have destroyed all other life forms and become the dominant creature in the universe.

That's possible. Tell on.

We'd like you to return to Skaro at a point in time before the Daleks evolved.

Do you mean avert their creation?

Or affect their genetic development so that they evolve into less aggressive creatures.

Hmmm... That's feasible.
