Onde está a espada falsa?
A última coisa que vemos, ainda está no cofre de Bellatrix (ênfase minha):
Harry shone his lit want around the vault: its beam fell upon glittering jewels, he saw the fake sword of Godric Gryffindor lying on a high shelf amongst a jumble of chains.
Deathly Hallows Chapter 26: "Gringotts"
É possível (mesmo provável) que a espada tenha sido removida do cofre pela subsequente avalanche de tesouros falsos (ênfase minha):
The tiny golden cup, skewered by the handle on the sword's blade was flung into the air. The goblin astride him, Harry dived and caught it, and although he could feel it scalding his flesh he did not relinquish it, even while countless Hufflepuff cups burst from his fist, raining down upon him as the entrance of the vault opened up again and he found himself sliding uncontrollably on an expanding avalanche of fiery gold and silver that bore him, Ron, Hermione into the outer chamber.

No entanto, presumivelmente, os duendes têm meios de trazer tudo de volta para onde pertencia; seu sistema de segurança não seria muito eficaz se eles não pudessem limpar depois disso, afinal.
A espada falsa nunca aparece depois disso
Onde está a espada real ?
Isso não está claro. O último que vemos, Griphook está levando para o meio de uma multidão de duendes com raiva:
Hardly aware of the pain from the burns covering his body, and still borne along the swell of replicating treasure, Harry shoved the cup into his pocket and reached up to retrieve the sword, but Griphook was gone. Sliding from Harry's shoulders the moment he could, he had sprinted for cover amongst the surrounding goblins, brandishing the sword and crying, "Thieves! Thieves! Help! Thieves!" He vanished into the midst of the advancing crowd, all of whom were holding daggers and who accepted him without question.
Deathly Hallows Chapter 26: "Gringotts"
Não vemos novamente até que Neville o remova do Chapéu de Classificação:
In one swift, fluid motion, Neville broke free of the Body-Bind Curse upon him; the flaming [Sorting] hat fell off him and he drew from its depths something silver, with a glittering, rubied handle - The slash of the silver blade could not be heard over the roar of the oncoming crowd or the sounds of the clashing giants or of the stampeding centaurs, and yet, it seemed to draw every eye. With a single stroke Neville sliced off the great snake's head, which spun high into the air, gleaming in the light flooding from the entrance hall, and Voldemort's mouth was open in a scream of fury that nobody could hear, and the snake's body thudded to the ground at his feet.
Deathly Hallows Chapter 36: "The Flaw in the Plan"
Na ausência de outras informações, temos que assumir que os goblins estavam mantendo-o em algum lugar seguro. De qualquer forma, não há mais duas espadas de Gryffindor por aí, o que me leva à próxima pergunta:
Snape está em perigo de ser descoberto?
Provavelmente não. Até onde Bellatrix sabe, a espada que estava na posse de Harry era a farsa:
"How did you get into my vault?" they heard Bellatrix scream. "Did that dirty little goblin in the cellar help you?"
"We only met him tonight!" Hermione sobbed. "We've never been inside your vault.... It isn't the real sword! It's a copy, just a copy!"
"A copy?" screeched Bellatrix. "Oh, a likely story!"
"But we can find out easily!" came Lucius's voice. "Draco, fetch the goblin, he can tell us whether the sword is real or not!"
Harry dashed across the cellar to where Griphook was huddled on the floor.
"Griphook," he whispered into the goblin's pointed ear, "you must tell them that sword's a fake, they mustn't know it's the real one, Griphook, please -"
[...]
"Well?" Bellatrix said to Griphook. "Is it the true sword?"
Harry waited, holding his breath, fighting against the prickling of his scar.
"No," said Griphook. "It is a fake."
"Are you sure?" panted Bellatrix. "Quite sure?"
"Yes," said the goblin.
Relief broke across her face, all tension drained from it.
Deathly Hallows Chapter 23: "Malfoy Manor"
Provavelmente deve ter parecido suspeito de que, apesar de alegar que é uma farsa, Griphook continua a segurá-la pela sua vida; então, novamente, os Comensais da Morte não são exatamente conhecidos por prestarem atenção às raças "menores".
Bellatrix presumivelmente acredita que a verdadeira espada ainda está em seu cofre, então a capa de Snape é segura.
No entanto, mesmo se veio à luz que a espada em culpa de Bellatrix era uma farsa, isso não necessariamente soprava a capa de Snape. É revelado perto do fim de Relíquias da Morte que Dumbledore escondeu a espada real dentro de seu escritório, enquanto deixava uma falsa em exibição (que é onde o falso se origina, lembre-se):
[Snape] approached the portrait of Dumbledore and pulled at its side. It swung forward, revealing a hidden cavity behind it from which he took the sword of Gryffindor.
Deathly Hallows Chapter 33: "The Prince's Tale"
Se o falso fosse descoberto, Snape poderia facilmente absolver-se da suspeita dizendo a verdade : Dumbledore plantou uma espada falsa, e todo mundo (inclusive ele 1 ) foi levado por ele.
1 Eu nunca disse que ele tinha que contar a verdade toda ...
