order of the phoenix;

In HP5 Moody appears at the very beginning of the book, when a selected group of witches and wizards of the Order of the Phoenix go to the Dursley's to take Harry to the Order headquarters.

Along the book, we see that Barty Crouch took very well the identity of the true Mad-Eye: Moody continues being as we saw in GoF. We can see he's a little rough and a little eccentric maybe, but that everyone trusts and respects him as the old and powerful auror he is. In fact we can't know a lot more than that about Moody in book 5... Anyway, we can see he cares as much as everyone about Harry; and we can confirm that Molly and Arthur Weasley have a high concept of him.

We'll see more of Alastor in the next books...? I hope so! :)
