Season 6 Episode 1: Doppelgangers

*NOTE* - The topic discussion starts at 28:02.
Throughout history, there have been stories about people seeing their exact doubles, or seeing perfect replicas of people they know. Turning up often in literature, these twins are often seen as being symbolic of our dual nature. Are these doubles just a work of fiction, or do they really exist?
In the Season 6 premiere, Krista and Kurt look at doppelgängers. And, as always, a taste-test and we answer listener questions!
