No need to worry, Julian, unless that bubble starts following you everywhere or chasing you. Patrick McGoohan was the protagonist in the series. You may remember him from the series "Danger Man" ("Secret Agent" in the USA.) In The Prisoner he portrayes a secret agent who quits the service for unknown reasons. He won't reveal the reasons. He is drugged and awakens in what seems an idyllic seaside village. Thereafter he is called "Number Six." His goal is to escape the village,...but he is always foiled in his attempts to do so. Every week, in the opening sequence, he demands to know "Who is Number One?" But he never finds out. Now we know!
