Mary Tamm: Romana

Quotes 

• The Doctor : Whenever you go into a new situation, you must always believe the best until you find out exactly what the situation's all about, THEN believe the worst.

  Romana : Ah, but what happens if it turns out NOT to be the worst after all?

  The Doctor : Don't be ridiculous. It always is.

• The Doctor : Where's your joy in life? Where's your optimism?

  Romana : It opted out.

  K9 : Optimism: belief that everything will work out well. Irrational, bordering on insane.
