I did not know.
Why did he sometimes wear a blue uniform?
He must be a Confederate spy; of course he is a Confederate spy.
My memory refused to abandon this man. I had known that I should recover the Doctor, and I had supposed that the Doctor's name would be the key to unlock all the past, so that my memory would be suddenly complete and continuous, but now I found the Doctor supplanted by a strange man whose name even I did not know, and who acted mysteriously, sometimes seeming to be a Confederate and at other times a Federal. I must exert my will and get rid of this man: he disturbs me; he is not real, perhaps. I have eaten nothing; I have fever; perhaps this man is a creation of my fever. I will get rid of him.
I forced the Doctor to appear. This time he was sitting in an ambulance, but not alone. The man was with him. I banished the picture, and tried again.
Another scene. The Doctor, and the man, and Willis lying hidden in a straw stack. Ah! Willis! That name has come back.
Who is Willis?
I do not know; only Willis.
It is a mistake to be following up the man. Can I not recall the Doctor without this disturbing shape? I try hard, and the Doctor's face flits by and vanishes before I can even tell its outline.
I forced the Doctor to appear and reappear; but he would remain an instant only and be gone; instead of him, this strange man persisted, and contrary to my will.
