<P> At the end of the story, Number 6 and Alice Drake have returned to London . 6 is clean - shaven and tidily dressed . Alice asks 6 who Number 1 was . 6 asks in reply, "Does the presence of Number 2 require the existence of Number 1?" He assures her that the secrets the Village sought from him are safe . "None of us would be here if they weren't," he says with a confident smile . </P> <P> Medically, Number 6 appears to be in good health . However, the episode "Free For All" reveals that he was required to eliminate sugar from his diet "on medical advice" (although he intentionally drops sugar cubes in his tea in "The Chimes of Big Ben" as an act of defiance). (This act had been also done earlier in the series .) He claims rarely to drink in "Dance of the Dead", and is seen to smoke only twice: once a cigar, and once in a dream sequence . "The Schizoid Man" establishes Number 6 as an at - least - occasional cigar smoker, as Number Two brainwashes him into preferring Russian cigarettes as a means of undermining his identity . Number 6 has repeatedly been under the influence of psychotropic and hallucinogenic drugs, and undergone periods of severe mental or physical stress without apparent effect on his health, although he has occasionally been driven to exhaustion by his ordeals . </P> <P> A few names are attached to Number 6 in the series, but it's impossible to tell if any of them are real . In "Many Happy Returns" he identifies himself as' Peter Smith' . Although it is possible that this is an alias, he does give it to a woman who has presented herself as the current owner of his car and tenant of his apartment . He in fact asks to examine the former's lease and the latter's log books, expressing surprise that both bear only her name . However, the house and car may have been acquired under one of Number 6's long - term false identities as a spy . </P> <P> In the episode "Do Not Forsake Me Oh My Darling", it is learned that Number 6 possesses numerous code names: Schmidt, Duval, and ZM - 73 . </P>
