Howling:Theories on "The Curator"

Spoilers for the 50th ahead!

So, as anyone who saw the 50th anniversary will know, Tom Baker made a surprise cameo playing... Well, playing someone. This thread is for speculation on who that person was. Here are some of the best theories going around:


 * He is a very-far-into-the-future incarnation of The Doctor.
 * He is The Watcher, from "Logopolis".
 * He is The Moment.
 * He is a Zygon (Four was the first to encounter them).
 * He is just a character who happens to look like Four.
 * He isn't really there, kind of like the ending of "An Adventure in Space and Time".
 * Another Time Lord, who goes quite literally by the name of "The Curator".
 * It's not important, just something to please the fans (not really a theory on who he is, but many have taken this view).

So what do all of you think? Do you agree with any of the above? Do you have a new theory? Or are you not bothered with who he is and are just glad that Tom Baker came back for the 50th? 87.102.91.126talk to me 18:29, November 26, 2013 (UTC)
