4. The Forest of the Dead
Who is this Doctor whom has saved my Library and myself? I can read every book in the Library, but they do not have information on what his motivation is, or more importantly, who he is!
Who are you Doctor? Who are you? You are more than the 'Oncoming Storm' the bringer of death and destruction of the myths and legends from thousands of worlds.
I know who you travelled with, Donna Noble. I know who she is and what her fate is.
River Song is not very forthcoming when I ask her about you. She keeps the information to herself, saying that very few people should know the Doctor's real identity. She may be right. That still doesn't mean I cannot ask the question. Who are you?
