I'm busy rereading the whole series (as I may have told elsewhere on this board ), and while reading PS I came upon the mirror of Erised. Now Dumbledore says this:
HP PS wrote:'I? I see myself holding a pair of thick, woollen socks.' Harry stared. 'One can never have enough socks,'said Dumbledore.
Now I got thinking, what with the upcoming war against Voldemort and his followers, and as Voldemort has gotten all kinds of dangerous allies, the dementors for instance, the good ones may need some help!
Well, what has that got to do with socks you might ask. Good question !
Who have got a lot of magic power, but don't use it properly? Who can be freed when given socks or clothing? That's right, House-elves!
Now, my theory is, that Dumbledore will use socks to free all the house-elves at Hogwarts (or at least will free them)! They'll all be payed to do the same work as they did, and, they'll start having normal lives! And most of all, they can help the order or the good ones in fighting Voldemort!
The SPEW and the fountain in the MoM, whose destruction might be seen as an allegory of the old relationships between wizards and others changing!, point, I think, in this direction..
Well, that's it! What do you all think, I'm soo curioous !
