Doctor Who (2009) Easter Egg - Waters of Mars

Waters of Mars is an anagram of either Masters of War or Master of Wars.
At first, I wasn't sure if this had any significance. However, when the Master was back in End of Time, along with the Timelords and the whole of Gallifrey, including the time war, I decided it was, in fact, very much intentional.
I thought it was neat :P RTD tends to do this a lot..
