Howling:Midnight Entity

I signed up just to discuss this theory, and its probably easily dismissed, but could the midnight entity possibly be The Master? I think its possible. From what i read about how in "The Waters of Mars" section, a scene where the doctor says he's there and there hasn't been any knocking and then suddenly there is a a knocking four times reminds me of the Midnight Entity. It also would help make sense as to why the Midnight Entity wanted to get rid of the doctor so much and The Master always did have that ability to persuade, just like the entity did with the other passengers in making it believe that the doctor was the bad one. Any thoughts?

I'm a seperate person, and I think this is correct. I have also developed a little theory for how he appeared on Midnight, and I think it is connected to both 'The Waters of Mars' and the ring...
