SILENCE IN THE TARDIS!

We've seen that the Doctor is not immune to the powers of the Silence.  So it's entirely pozz'ble, just pozz'ble*, that one of their number has been hitching a ride in the TARDIS over the years with earlier incarnations of the Doctor.

 

These mash-ups show us what it may have been like if the Doctors played by Mssrs. Hartnell, Troughton, and Pertwee faced off against the Silence.  Of course, none of them would have remembered the encounters.  

I'm hoping that eventually we'll see mash-up pictures of the other Doctors as they encountered these alien invaders in the TARDIS.  With the last Silence seen above, he must have been located at U.N.I.T. headquarters while the Third Incarnation was basically "incarcerated" there without access to the full capabilities of the TARDIS. 

BCnU!

*Sorry.  I never get tired of that 'Deputy Dawg' phrase.  You'll just have to live with it......
