I especially liked the panel where Harry said "you are such a git, you know that?" -- the way it's smaller than the panel above and from a different angle with no text dectly on it, so that it changed the pace, so that I paused on that panel.
There was a similar great pause the moment Teeny Nagini showed his (her?) fangs. And then I was laughing as I realized that yes, Trevor was going to eat Nagini! Oh the indignity! :-D
