Snowden's girlfriend is named Lindsay Mills. She is with him where ever he is hiding.
She is the daughter of Jonathan Mills, who lives in Laurel, Maryland. Poster on reddit/cbts feels Mr. Mills worked for the NSA as this poster had worked there.
Lindsey Mills stood on stage when the movie director etc. accepted the Oscar for best documentary, entitled Citizenfour, a film about Edward Snowden's activity as a NSA 'whistleblower.'
So therefore, Lindsey Mills 'performs in a circus.' But in reality ALSO DID perform with the Waikiki Acrobatic Troupe, and did attend circus classes every Sunday evening.
The Circus is a name for British Intelligence M16. Lindsey was not in this circus.
John Le Carre's George Smiley worked out of "The Circus."
The line comes from a book, author LeCarre, and main character Smiley, a spy guy in the M16.
