I haven't read to books in a long time, but maybe Sirius told him...

(I know, it's very unlikely.)

Dumbledore might have also knew, everyone trusts him.

(This is a bit more likely, but still very unlikely.)

Once the subjects of the charm were killed, the charm was broken. Remember when Harry went to Godric’s Hollow with Hermione, they were both able to see the house.

But everyone who is told becomes a secretkeeper, right? So was Hagrid told?

That’s only if the secret keeper dies. Sirius was still alive, so that doesn’t apply. If the subject dies (James and Lily in this case) the charm just ends because there is no longer a secret to protect.

Right, so it shouldn't be possible?

Infinity, James and Lily died, Peter was to keep the secret of James and Lily. I don't get what you don't understand.

I'm talking about Hagrid picking up baby Harry, not their deaths. It shouldn't have been able to happen because of said Fidelius charm, that's the post's point.

How do you not understand this?! The spell is broken because James and Lily died!

Sorry, my bad, I don't know how I got so confused, but calm down.

But thanks for telling me, sorry for the aggravation.
