This means that the four knocks does not refer to The Master.And the sound of drums - they may be haunting the Master, but we're obviously going to find out the reason why, SOMEONE is causing it. Saxon 3 15:53, November 23, 2009 (UTC)

Someone OR someTHING, possibly the Eternals or the Time Lords. --Revanvolatrelundar 16:04, November 23, 2009 (UTC)

Notice aswell that it says wastelands of London, any idea why London would be a wasteland? On the commentaries for WOM R.T.D an David T. were talking about when The Doctor chased The Master across the wastleand.Saxon 3 16:13, November 23, 2009 (UTC)

The way the synopsis is worded makes it seem like the Immortality Gate is a location beyond the Doctor or the Master's control, could be a time lord construction ensuring the survival of the Time Lord race (hence immortal).--Revanvolatrelundar 16:16, November 23, 2009 (UTC)
