Is there any evidence as to how Regulus found out about the horcrux? Everything I've been able to find has just referenced that he found it somehow, but not the actual how.

Thank you!

I'm in the process of planning out a fanfic, and I wasn't sure about the details of the diary as a Horcrux. Is it canon that Voldemort used the murder of Moaning Myrtle to turn the diary into a Horcrux, or is that just an assumption I've made in my head? I've checked the HP Lexicon and came up empty. Any help would be appreciated.

Thanks for your

Hello there--we've a theory floating around up here (and we know it's been theorized already--but we want a canon-based theoretical approach, not fanon).

Is it possible that Harry could be a Horcrux? It seems to me that Horcruxes must be established BEFORE the possible death occurs, yes? Any and all thoughts are highly appreciated! Thanks, guys

Okay, so Harry tells his friends about the Horcruxes. But does he tell them everything he saw in the Pensieve? I'm trying to find out if Ron and Hermione know which people have had the locket so far.

Thanks in advance. :)
