Is Rory the Master?!!!!! 

DEFINIETLY NOT!!!!!!The time lords know who is a time lord too!!!!Don't u remember that???? When the Master was "Harold Saxon", the Doctor know him!!!And,if he's using the "Chameleon sistem",he will hold a watch everytime with him!!!And the "human time lords" are VERY clever!!! We have seen this when the Doctor was "John Smith", and when the Master was "Yana".The DOCTOR have said he's brilliant!!!

It would make even less sense! The Master is dead! He was hurled into the Time war, The Doctor would have to somehow manage to brake the Time Lock, save Gallifrey and thus stop Rossilon from trying to end time.

I am really perplexed, as more and more people are supporting the speculations...
