Also some new pics;

Cedric and Cho at the ball are of note, I'm starting to become a big fan of the girl who plays Cho!

The Dark Mark, as discussed above.

What I believe is Harry and Lord Voldemort duelling (not the best shot).

Lord Voldemort!
There is a shot at around 1:41 where for the life of me, I can't make anything out about it, heads or tails. It follows immediately after Sirius says 'the devils are inside the walls', and we switch to a scene with a giant snake, with a youth kneeling down infront of a large armchair (which is faced away from us).
Now the giant snake is obviously Nagini, but the youth is most definately
not Wormtail, or the grounds keeper who was murdered (as he was said to be old). I can come up with only two explainations.
First (and most likely), they've tampered with some of the Barty Crouch Jnr story, and this is part of his flashback, where he is revealing everything that has happened to Dumbledore (which actually makes quite good sense). Or second (and least likely) the youth is meant to be a young Tom Riddle Jnr (Lord Voldemort) flashback ... I think the first explaination makes more sense really, so I'm going with that.
