Character mistake: The miniaturized TARDIS crew never interact with the other characters in this story, because, as the Doctor points out, the 'giants' will be unable to hear them, as their voices will be on a different wavelength. So why does the Doctor later suggest using the telephone to try to call for help?

The Doctor: That's the trouble with regeneration, you never quite know what you're going to get. (00:12:15)
Trivia: This Doctor Who story was originally scripted and produced as a four-episode story, but, just two weeks before transmission, upon viewing the story, co-creators Sydney Newman and Donald Wilson felt that the final two episodes (Episode 3, 'Crisis'; and Episode 4, 'The Urge to Live') should be combined into a single episode. The new 'condensed' episode incorporated the opening titles of 'Crisis' with the closing credits of 'The Urge to Live'.
Question: If The Master had closed the CVE it would have resulted in the total destruction of the universe. Would he have really closed the CVE if the peoples of the universe hadn't responded to him? Isn't that the complete opposite of what The Master wants, i.e. complete control of the universe? Also, if the universe had been destroyed, who and what would he have left to control?
Chosen answer: The Master is insane. If he can't control the universe, he'd rather see it destroyed.
