Castellan and The Doctor in “The Invasion of Time”

Is there anything else I can get you, sir?

Yes. A jelly baby. My right-hand pocket.

What color would you prefer, sir?

Orange.

There doesn't appear to be an orange one--

[Seizing Castellan by the arm] One grows tired of jelly babies, Castellan.

Indeed one does, sir.

One grows tired of almost everything, Castellan.

Indeed, sir.

Except power.
