Is romantisk kärlek som kan utlösa "kärleksskydd" charm?

Förmodligen. (Även om detta är ganska ovanligt och avancerat magi, och det är de enda två fallen i kanonen.)

Den bästa diskussionen om det här jag kan hitta kommer i en JK Rowling intervju i 2005 med The Leaky Cauldron och Mugglenet , där hon diskuterar aspektet av offerskydd, och om det skulle ha fungerat för James:

ES: This is one of my burning questions since the third book – why did Voldemort offer Lily so many chances to live? Would he actually have let her live?

JKR: Mmhm.

ES: Why?

JKR: [silence] Can't tell you. But he did offer, you're absolutely right.

Don't you want to ask me why James's death didn't protect Lily and Harry? There’s your answer, you've just answered your own question, because she could have lived and chose to die. James was going to be killed anyway. Do you see what I mean?

I’m not saying James wasn't ready to; he died trying to protect his family but he was going to be murdered anyway. He had no – he wasn't given a choice, so he rushed into it in a kind of animal way, I think there are distinctions in courage. James was immensely brave. But the caliber of Lily's bravery was, I think in this instance, higher because she could have saved herself.

Now any mother, any normal mother would have done what Lily did. So in that sense her courage too was of an animal quality but she was given time to choose. James wasn't. It's like an intruder entering your house, isn't it? You would instinctively rush them. But if in cold blood you were told, “Get out of the way,” you know, what would you do? I mean, I don't think any mother would stand aside from their child. But does that answer it? She did very consciously lay down her life. She had a clear choice—

ES: And James didn't.

JKR: Did he clearly die to try and protect Harry specifically given a clear choice? No. It's a subtle distinction and there's slightly more to it than that but that's most of the answer.

Jag tycker att det är modet, och det faktum att de valde att dö snarare än att låta den andra personen skadas, som gav skydd. För mig här läser det som om Jakobs offer skulle ha skyddat Lily och Harry, om han hade erbjudits det valet . Så det kan fungera för romantisk kärlek.

Du kan kanske gå vidare: kanske är detta skydd tilldelat om du erbjuds valet att leva, men offra dig själv för att skydda någon som du egentligen inte älskar. Eller skulle det falla under "kärlek till dina medmänniskor"? Den ovanliga aspekten av Lily's mord var valet , mindre hennes mammas kärlek till Harry (även om det säkert hade en roll i det).

(Observera att denna intervju skrevs före publiceringen av Deathly Hallows , så att det faktum att Snape älskade Lily, och frågade Voldemort att spendera henne, var då okänd. Det kan vara varför han gav henne ett val. Om det var Nevilles mamma på linjen är jag säker på att hon skulle ha gjort samma val, men det skulle aldrig ha blivit erbjudit.)

Tänk också på att det var romantisk kärlek mellan Harry och Ginny när han offrade sig i Deathly Hallows , men det kan ha varit en del av den bredare "kärleken till medmänniskor".

Observera också att i samma intervju får vi bekräftelse på att detta är en oförklarad och okänd gren av magi:

MA: Did she know anything about the possible effect of standing in front of Harry?

JKR: No – because as I've tried to make clear in the series, it never happened before. No one ever survived before. And no one, therefore, knew that could happen.
