Steve M.

Steve M. once saw the Ninth Doctor scrawl a sequence of numbers, 23 6 801, on a wall. Steve later wrote about his encounter on the conspiracy website Doctor Who? in March 2005. (PROSE: Have You Seen This Man?)

Behind the scenes
As the sequence of numbers, 23 6 801, reportedly a bit of "misleading fun" by the production team, it is possible Steve M.'s entry was written by a member of the crew.
