An interesting step up in the story line. We now have a pretty good idea who's helping Voldiemort; I wonder if he realizes who "Jericho" really is? For that matter, it should be "interesting" to see what the reactions are when Dumbledore and co. recognize who "Jericho" is. I can see some very interesting times ahead.
The real interesting times won't even start till Chapter 7. Everything building up now is set to snowball down the mountain later.
A small spoiler, but nothing that will give anything away, (just something to tease you with) a HUGE clue about Jericho/Harry's past is revealed, if you spot it and take time to think about it you may learn why he is called Jericho and not Harry. Anyway that's some food for thought for everyone.
