Is there a reason why the Potters couldn't be their own Secret-Keepers? Wouldn't that have been much safer? 18:01, December 20, 2009 (UTC)

That would've been much safer, yes. Minor whole in the plot there, but easily explained when you think that being your own Secret-Keeper would be a very paranoid thing to do, and James thought it quite dishonorable to distrust his friends. It was his tragic flaw after all. Mr Norrell 14:24, March 11, 2010 (UTC)
Having just re-read Deathly Hallows this question perplexed me as well, almost to the point of removing my enjoyment of the book. It doesn't seem that you can't be your own secret keeper (Bill Weasley was secret keeper for his own house, Shell Cottege) not that it would 'isolate' them from the outside world, they could reveal the secret to whomever they wanted, who could then visit them, but would not be able to then reveal that location to others. For me, the best explanation is that the secret keeper must also be the spell caster, and as very powerful magic, both Lilly and James were unable to successfully cast the spell, necesitating someone else to do so for them. Why a Wizard like Peter Pettigrew could do so, when, seemingly much more accomplished Wizards and Wiches like Lilly (who was top of her class) and James (who was de-facto leader of their group) could not is a different question, but as we see in HP7, Hermione Granger has a problem producing a Patronus, so the fidelius charm could just be a spell they struggled in, and Petigrew excelled in. Perhaps the stress of going into hiding somehow interfered with their ability to successfully and strongly cast the charm themselves, so they relied on their friends, which would not be a problem for them, as they trusted their friends implicitly.

It could be that James himself to stay put and do nothing. The thought that he might be tortured into revealing Lily and Harry's location being to much to bare, he decided it would be safer if an outsider was the secret-keeper.Tjb173 (talk) 01:04, March 19, 2013 (UTC)

I don't believe you must spell the cast yourself to be Secret-Keeper. As I understood the story, Dumbledore himself had cast it and the Potters chose to make Pettigrew the secret-keeper. Dumbledore has offered the Potters to be their secret-keeper, but they wanted to make Sirius secret-keeper and sadly decided at last to choose Pettigrew.  Harry granger   Talk   contribs 12:04, January 6, 2012 (UTC)

After Dumbledore died Snape would become a secret keeper, along with the other members of the Order, for 12 Grimald place so why cant the Death eaters get in when Harry, Ron & Hermione are hiding? Wouldnt Snape tell them or Voldermort figure out that he is a secret keeper & make him?

Voldemort believed Snape was on his side, and suspected nothing of Snape being a double agent; considering the conversation that Harry and Voldemort have in the end of book 7, presumably this was in fact the case. Chances are Snape did or said something to Voldemort to convince him that there was nothign at 12 Grimmauld Place that was worth going back for and that no one was using it anymore.

As I understood the last book, Moody and Dumbledore took precautions against Snape - Moody (tongue) and Dumbledore (attacking dust figure). So it could be possible that Snape could not tell Voldemort because of this precautions.  Harry granger   Talk   contribs 12:04, January 6, 2012 (UTC)

The secret

Why could Harry, Hermione and Ron not get back to 12 Grimmauld Place when they revealed the secret to Yaxley. As i understand the Fidelius Charm, Harry and Hermione revealed the Black House to Yaxley, but they only told him the place. He was not able to tell others.

I think the point was that with the original Secret-Keeper (Dumbledore) dead and everyone who knew at that time becoming new Secret-Keepers, anyone those Secret Keeepers told would in turn become Secret-Keepers. Yaxley would thus indeed be capable of telling the other Death Eaters the secret.

And even if he couldn't reveal it and the Trio just had an Idiot Ball moment, I wouldn't want to keep living in a house a known killer can get into just because his friends are locked out. 04:22, July 14, 2011 (UTC)

But besides that one about living in a house with a known killer, no Yaxley would not be able to tell anyone else about 12 Grimmauld Place. Hermione was Secret-Keeper and accidentally told Yaxley, but he would not be able to tell it as he wasn't Secret-Keeper. That post can only be given to the next person if the original dies. And only Secret-Keepers can reveal the location. Furthermore Yaxley was only one person against three, which leads to the question as to why it would be dangerous to be there. ---- 11:19, July 5, 2012 (UTC)

shell cottage

The Fidelius charm wasn't placed on Shell Cottage until after the trio escaped and the Weasley family had to go into hiding. —The preceding unsigned comment was added by Tjb173 (talkcontribs).
