I have been reading about some of the theories people have been coming up with about the Harry Potter characters. As one theory that I came across and think is absurd is the idea that Hagrid is a secret death eater as Hagrid was very pro Dumbledore.
Hagrid also said that Albus Dumbledore helped him out when Hagrid’s Father died and being a half giant would not have been easy.
As perhaps many witches and wizards held something against giants which is why many giants relocated.
Also, perhaps Albus Dumbledore took it upon himself to find out where the remaining giants relocated to as where they ended up living weren’t as widely known.
Then maybe The Ministry for Magic rounded the giants up and forced them to relocate? As they also forced the Centaurs to live in The Forbidden Forest.
Dumbledore could have known that The Ministry of Magic knew where the remaining giants were. As Albus Dumbledore suggested to Cornelieus that he send envoys to the giants and make peace with them.
As Albus Dumbledore knew that Voldemort was sending some death eaters there. As The Dark Lord wanted to recruit the giants.
Cornelieus refused to do this, and so Albus Dumbledore ended up trying to make peace with the giants himself by sending Hagrid. As perhaps Albus Dumbledore sent Hagrid as he knew that Hagrid had always wanted to see his, Mother again one day.
However, while Hagrid was there, he found out that his, Mother had died. but he had also discovered that he had a younger brother named Grawp.
Hagrid then went to find Grawp as he wasn’t going to leave Grawp behind after he found out that he had a brother.
There is also another theory that Albus Dumbledore repaired Hagrid’s wand and transfigured it into an umbrella as he believed in Hagrid’s innocence.
Some have also come up with the theory that Albus Dumbledore may have continued Hagrid’s education by teaching him advanced spells in secret.
When perhaps not many would’ve.
Albus Dumbledore also decided that he had to make it his mission to find out as much about Tom Riddle as he could.
This realization was probably what made Albus Dumbledore decide to form a group that he led, and the group was called The Order of The Phoenix.
Then why Albus Dumbledore formed this group is because there was a lot of deaths and destruction as Voldemort was causing a lot of mayhem.
Hagrid was also a member of the original Order of The Phoenix. So, maybe Albus really did repair Hagrid’s wand and transfigured it then taught him advanced spells.
Tom Riddle had also told Harry that Albus Dumbledore kept an annoying close eye on him after he framed Hagrid when Harry and Voldemort were talking in The Chamber of Secrets.
As Harry said to Tom you framed Hagrid.
I can also see why Hagrid would want to get involved in a group that was fighting against Voldemort and, his followers too.
Though Dumbledore said to Harry that he didn’t know that Voldemort had created a Horcrux until Harry showed him Tom Riddle’s diary.
As Harry also explained to him what happened when he and Ginny were in The Chamber of Secrets with Tom Riddle.
Albus also told Harry that there are ways that Voldermort can come back in Harry Potter and the Philosopher’s Stone.
Albus Dumbledore also guessed things that were later on proven true about Harry like Harry’s connection with Voldemort through his lightning bolt scar etc…
However, Albus Dumbledore didn’t tell Harry then what he expected that Voldemort had done until years later when he was giving Harry private lessons.
As why he didn’t say anything to Harry was because Harry was a kid. Albus Dumbledore also wouldn’t want to say anything about Voldemort to Harry until he was certain.
As what Harry had told and showed his headmaster in Harry’s second year probably did, convinced Albus Dumbledore that he needed to have a discussion with Horace Slughorn.
As Horace did give Albus Dumbledore the memory he needed.
Though it was rather obvious to Albus Dumbledore that Horace Slughorn did tamper with the memory Horace gave him.
Hagrid also had an unusual affection for monsters like Aragog the spider and Fluffy the three headed dog and who can forget the dragon Hagrid named Norbet?
As certainly Hagrid would’ve had some unkind experiences with people because some people would’ve known that he was a half giant.
There would’ve been people too that wouldn’t have understood why Hagrid liked creatures that people were usually afraid of.
As perhaps this had led to Hagrid and Aragog becoming friends?
As Aragog was trying to talk Hagrid into helping him leave the castle. However, they were interrupted by Tom Riddle and Aragog had to escape.
While Hagrid ended up being expelled but because of Albus Dumbledore Hagrid was able to stay at Hogwarts.
As Hagrid after being expelled then assisted with then game keeper of Hogwarts. Then years later Hagrid was the game keeper.
Another theory that I don’t think happen is that Hagrid was told by Wormtail where to find Harry, when Harry’s parents were killed, and their house was wrecked.
As Hagrid was in a pub and was in the company of other teachers and Fudge, the then Minister of Magic when he told them that Sirius Black gave him his motorbike. As Hagrid wouldn’t hand Harry over to Sirius so Sirius gave Hagrid his motorbike instead.
Hagrid also didn’t need to be told where to go to find Harry. As the charm was broken when Wormtail told Voldemort.
So, all Hagrid need to do to find Harry was to look for a house that showed signs of severe damage from magic.
As perhaps Hagrid knew from Albus Dumbledore that magic does leave traces.
Also, perhaps the people that are non-magical could see that something bad had happened before it is covered up by witches and wizards.
