Possibly one of the most iconic speeches in the show's history despite its brevity, the Doctor's stark warning not to blink manages to instill fear in a few short seconds.
Its terse tone impressed the seriousness of the situation upon Sally and Larry (and the audience, for that matter) quite quickly, and few of the show's speeches have imparted such a haunting tone in such a short period.
Paula Luther hails from Pennsylvania and has been an avid Whovian since 2008. She enjoys writing (obviously), reading, collecting model horses, square dancing, video editing, and building websites. She would love a chance to play the Doctor on TV--failing that, she'd ask nicely if the powers-that-be would let her write an episode.
