I am glad Harry has been able to keep what happened secret. I look forward to what you have planned next and what will the Headmaster do if he can't find the diary he would think the Dark Lord only made one Horcrux and it was Harry. Killing Harry or trying to would make the Headmaster look bad and give Harry a very good reason to turn on the old man.
Will there be an epic twist regarding the potion to restore Hermione and the others will Harry alter or tait it so it kills them instead as with Harry under the Dark Lord's influence Snapes value has decreased and a spell in Azkaban might make the man more loyal to his former master and allow Harry some fun as Snape will be punished for his part in killing the Potters and for the downfall of the Dark Lord while Albus looses his only spy.
