Perception Filters working on Time Lords
Its noted in the article that Perception Filters do not work on time lords, and cites "The Sound of Drums" as the source, but after just reviewing a few key scenes from the episode, it appears that it does work on them. The Master doesn't acknowledge the Doctor until he makes a run for the Master, and as mentioned earlier in the episode, running, sudden moves, or drawing attention to yourself will break the effect. Is there any other points to cite showing that perception filters don't work on Time Lords?

Addendum: Ok, the Master does say 'As if a perception filter is going to work on me.'  That could mean that he is intelligent enough that it won't work, OR it doesn't work on Time Lords, however the question still stands, is there any other evidence that it doesn't work on Time Lords in general? -- Kooky 04:44, 12 February 2009 (UTC)
