You are Number Six

The Prisoner, Patrick McGoohan, dead at 80.

Yesterday, Khan Noonien Singh (Ricardo Montalban) died at 88.

Imagine the conversation:

"Where am I?"

"You didn't expect to find me...you thought this was a dead planet. Tell me: why are you here?"

"Whose side are you on?"

(Come to think of it, that gets too silly, too quickly...never mind.)
