At the end of Harry Potter and the Deathly Hallows, when Harry Potter pulls out the Golden Snitch, a line appears on it—open at the end.
This sentence not only hints at where the Resurrection Stone is hidden, but more importantly, in the last Harry Potter, there are several details that echo the first Philosopher's Stone.
This Harry Potter feast is coming to an end, but at the same time, it is also a new beginning.
<h1 class="pgc-h-arrow-right" data-track="3" >1, chocolate frog</h1>
In Philosopher's Stone, when Harry first opened the chocolate frog package, the frog "came alive," jumped on the train window, and slipped out of the gap.
In the finale of the Deathly Hallows: Part 2, Harry sends his youngest son, Albus Severus Potter, onto the Hogwarts train, and little Albus sits down in the carriage and sees a chocolate frog lying on the window.
Of course, this is not the same frog, but it implies that another cycle of reincarnation has begun, and the grandchildren have arrived.
<h1 class="pgc-h-arrow-right" data-track="5" >2, brave Neville</h1>
Neville's first highlight was in The Philosopher's Stone. When the Golden Triangle was about to violate the school rules, Neville stepped forward to stop them. In Dumbledore's words, "We need superhuman courage to deal with our enemies, and it takes a lot of courage to stand our ground in front of our friends."
At the final Battle of Hogwarts, Neville had the most important moment of his life, this time facing not his friends, but his most fearsome enemies, Voldemort and Nagini. Neville stood up again, refused Voldemort's persuasion, and bravely killed Nagini.
<h1 class="pgc-h-arrow-right" data-track="7" >3, the lights out of the "appearance" again</h1>
At the beginning of Philosopher's Stone, Dumbledore uses a lights-out to extinguish the street lights on Four Privet Road. At that time, the lights-out was not yet called the lights-out (put-Outer in the original English version of the Philosopher's Stone).
In Deathly Hallows, the lights-out appears again (officially named Deluminator in the novel) and is left to Ron as a relic of Dumbledore. In one part, it is used to extinguish the lights, while in the last part, it is used to point the way.
<h1 class="pgc-h-arrow-right" data-track="9" >4, Hermione's bad encounters danger</h1>
In Philosopher's Stone, Hermione hides alone in the bathroom to wipe her tears, only to be attacked by a troll, and with the help of Harry and Ron, the three of them become good friends.
In Deathly Hallows, Hermione is in distress again, this time nearly being killed by Bella Cretes. Fortunately, Dobby appeared in time, and with his help, Harry and Ron rescued Hermione again.
<h1 class="pgc-h-arrow-right" data-track="11" >5, Hagrid holds Harry</h1>
In Philosopher's Stone, Hagrid drives a flying motorcycle and carries the swaddled Harry to Four Privet Road. In the 7 Harry Transfers battle at the beginning of Deathly Hallows, hagrid drives Harry away from Privet Road.
In the final Battle of Hogwarts, Hagrid returned to Hogwarts with Harry in disguise. I have to say that Hagrid has been with Harry from the beginning to the end.
