11 Great Moments From The Eleventh Doctor's First Season
9. Negotiating With The Silurians In "Cold Blood"
Whovians were delighted at the return of the Silurians, the reptilian race that inhabited Earth before the rise of the humans. They had been a memorable part of the show's lore since their introduction in the Third Doctor's era, so the return of a classic foe for a new Doctor was eagerly anticipated.
This return gave the Eleventh Doctor a chance to show off his diplomatic skills in an attempt to forge peace between the Silurians and the humans. It was thanks to these efforts that a war was narrowly averted.
