In 'The Prisoner' No.6 has this somewhat curious habit of looking through undergrowth. He does it several times throughout the series, as he does below while following the doctor-No.14 through the woods in 'A B and C.'
This is a trick which has not gone un-noticed, and used in THEPRIS6NER-09, as Six watches the doctor-313 leave her house in the episdoe of 'Anvil.'
I have never been sure if peeping through undergrowth was a strange quirk of Pat McGoohan's, or that of the character of the Prisoner-No.6. Mind you McGoohan does the same thing in several episodes of 'Danger Man.' So it's probably six of one and half a dozen of the other!
Be seeing you
