Back in time, Harry and Hermione were waiting anxiously in Professor Lupine's office.
"We can't stay here and do nothing, Hermione!" Harry paced back and forth in the room, saying irritably, "Peter Pettigrew is about to escape, we should go to the Forbidden Forest to help Ivan catch him."
"No, Harry!" Hermione shook her head and hurriedly stopped him, "We can't go out, have you forgotten? The few of us should all be in the hall on the first floor, you can't take the risk if someone finds out"
"I know, since we can't get out, isn't Aiwen the same?"
"He is different from us. He is an Animagus. His Animagus form is a black cat. He can slip out of the castle at will without being noticed." Hermione also looked very worried. , but quickly returned to calm, "Trust Ivan, Harry, he will catch Peter Pettigrew."
Hearing her words, Harry clenched his wand tightly and remained silent without speaking.
"Harry, there's something I don't understand. Why didn't the dementors catch Sirius? I remember them coming and then I probably passed out, my last impression was that there were so many of them"
Harry sat down too, and he told Hermione what he had seen. He told her that when the dementor closest to him was about to put his mouth near his, two silver objects flew out of the castle, forcing the dementor to retreat and flee.
"Silver stuff?" repeated Hermione, seemingly unresponsive.
"There's only one thing that can keep a Dementor away, Hermione!" said Harry, "and that's a real Patronus, a powerful Patronus."
"But why are there two?" Hermione opened her mouth a little, and said with a puzzled expression, "Could it be Professor McGonagall and Professor Flitwick who summoned it?"
"I don't think it's them. They should be in the auditorium and don't know what's going on outside." Harry shook his head, trying to think about the shapes of the two patron saints.
"Will it be Dumbledore or another teacher?"
"No, those two Patronuses were definitely not summoned by any of the teachers." Harry whispered, becoming more and more sure.
"It must be two truly powerful wizards who can drive away so many dementors. I still remember that the patron saint summoned by Aiwen at that time only lasted for more than ten seconds in front of more than a hundred dementors. What if those two Patronuses could shine so brightly without illuminating themselves? You can't see"
"I didn't see who summoned them, and the two Patronuses finally parted over the castle," Harry said slowly, "but I think I should know who they are!"
Hermione said nothing, she stared at Harry closely.
"I think" Harry swallowed, knowing how weird that sounded, "I think it was my mum and dad."
Harry glanced at Hermione, seeing that her mouth was completely open and unable to close, and she stared at him with a mixture of panic and pity.
"Harry, your parents are already," she said quietly, "well, you know, they're dead!"
"I know," said Harry quickly.
"Then do you think that what you saw was their ghosts?"
"I know it sounds like crazy, but those two Patronuses"
Before Harry could finish his sentence, there was a dull explosion sound outside the castle. The distance was too far away, and he couldn't hear it if he didn't listen carefully.
"It's Peter Pettigrew's magic, he fled to the Forbidden Forest immediately." Harry hurriedly got up from the ground, "We have to get out, Hermione!"
"No, we can't, people will find out"
"We won't be seen, we don't have to go to the hall," said Harry hastily, "just go to the corridor windows, I just want to see who summoned the two Patronuses."
Harry turned and rushed out of the office, not knowing why, suddenly thinking of his dad, and of his three old friends, Moony, Wormtail and Padfoot.
Tonight, Wormtail reappeared, and everyone thought he was dead long ago!
But he is still alive, so is it possible that his father and mother also have this possibility? Harry can be sure that the two patron saints are related to his parents.
If it is them, they must know, need to see
He rushed to the narrow window in the corridor and opened it. The cold wind was blowing in. He saw himself and Hermione sitting slumped by the Forbidden Forest, with Sirius Black and Ron lying behind them, the four of them were Dementors swarm in the very center.
He hurriedly looked in the direction of the castle gate, but there was nothing there.
Hermione also followed. She covered her mouth and looked at what was happening outside in horror. The two of them were trying to summon the Patronus, but it was useless because there were too many dementors.
Beside the Forbidden Forest, two little silver glitters were struggling.
It was their own Patronuses, and one of them went out, Harry knew, and Hermione passed out. He almost leaned most of his body out of the window, desperately looking around, but there was nothing, not even the other professors.
A few seconds later, the last silvery flash also dissipated.
A shiver of fear flashed through Harry, the two Patronuses might show up at any moment
"Come on!" he murmured, looking around. "Where are you? Father, mother, come on."
But no one came, and Harry looked up at the circle of dementors outside the Forbidden Forest, one of which was lowering its hood towards him.
A savior was supposed to be there, but no one came to help this time.
"We have to do something, Harry!" screamed Hermione, and it would be too late if the dementor wasn't stopped.
Hearing Hermione's shout, Harry suddenly understood something. He raised his wand high and shouted, "Call God to protect you!"
What emerged from the end of his wand was not a shapeless mist, but a blinding silver animal.
Harry squinted his eyes, trying to see what it was.
It looked like a horse, with pointed horns on its head, and it was one of the two patron saints I saw at the time. It left him and charged across the black night sky towards the horde of dementors outside the Forest. At the same time, a silver-white figure rushed out from the hall.
The two Patronuses were intertwined, they looked so similar, so perfect, they gathered together and rushed towards the dementor.
Outside the Forbidden Forest, the dementors ran in circles, retreating, breaking apart, disappearing into the darkness, and fleeing in all directions. Then the two Patronuses turned and ran slowly back across the night sky in the direction of the castle.
Harry saw clearly this time that the two Patronuses were not horses or unicorns, they were as bright as the moon in the sky. The patron saint I summoned was looking at me with those big silver eyes, and it slowly lowered its head with antlers.
Harry understood that it was a stag.
The patron saint next to my stag patron saint is much smaller and has no horns on its head. It looks like a
"A doe!" said Hermione softly. "It's a doe, Harry!"(.)
