I hate to say i told you so but i said that the revelation of "You Are Not Alone" would lead to the reappearance of The Master back in April after Gridlock i believe it was ?

Excellent performance by Derek Jacobi and it was good how the relationship problems between the Doctor and Cap'n Jack was resolved, nice to tie up loose ends...

Seriously looking forward to the last two episodes now...

We always figured it was the Master, though I wanted (and still hope) that Susan will reappear.

The Professor Yana name was really kind of funny.
