== Brain of Morbius == 

 I added a REFERENCED explanation for who the faces shown in this episode may be. The Discontinuity Guide, published by Virgin Books in 1995, suggests that the faces may be younger faces of the first Doctor. This seems a valid contribution and is sourced. Certainly equal to the other sources which also provide speculative answers to who these faces may be. My edit was deleted with the comment that speculation has no place in the article. You have now selectively restored some speculation, but not mine. I don't see the difference.
