|No, I don't know why he didn't just make Harry's pillow a portkey.|
I know that the next three books, the rest of the Gospels, also tell of same time line but right now I'm not sure how I feel about that. On the one hand, I think it's interesting to hear another side of the same story. (Wasn't that the gimmick behind Carol Shields' Happenstance?) On the other hand, four different versions sounds like it might be overkill.
In the meantime, Jesus as a character is quite interesting. So many are suspicious of his motives but Jesus tends to respond with questions and parables, which really doesn't help his case. Not his immediate case, anyway.
