Reading this was the first time I felt an actual, sympathetic interest in Anakin as Vader. The way he could recall the room perfectly, just the way he had seen it as a boy, and yet not be able to see Obi-Wan - that was really strong. The following paragraph is what clinches it; it's wonderful. It makes him something lovely.

I think your last sentence could be streamlined a little, but only to give it more punch. (Do you even want comments like that?)
