The theory suggests that had Ron not returned as he did, Snape would surely have saved Harry's life instead. Fans will recall that it was Snape who had conjured the Patronus in the first place to lead Harry to the Sword.
If Ron died, well it would be Hermione being devastated and Harry would of course help his friend mourn him while doing so as well. Then they would honor his memory and go on to destroy the Horcruxes as they were meant to.
Harry's friendship with Ron would be off to a rocky start. Even after their friendly meeting on the train, Ron would avoid him as he believed all Slytherins to be evil. But sooner or later, he would realize that Harry's different from Draco and the others, and would become his friend.
The theory posits that Ron became radicalized from a young age, clinging to Harry when the pair first attended Hogwarts. Depending on the Second Wizarding War's outcome, Ron would have been in a win-win situation based on his secret identity as a Death Eater.
Ari Ron seemed to be most effected by the locket Horcrux. He left because it intensified all the negetive feelings he already had: Jealousy at how easy Harry and Hermione's friendship was, hunger, frustration, fear, desperation, his quick temper and tendency to jump to conclusions, concern for his family...
The REAL Reason the Weasleys Are So POOR (They're CURSED) - Harry Potter Theory
Why did Hermione not hug Ron?
In the film, she only hugs Harry, and just gives a hesitant handshake to Ron (Note: This was the result of Emma Watson being hesitant to hug both Daniel Radcliffe and Rupert Grint in public view, with her hugging Radcliffe during filming having to be frozen for a few seconds to get the desired effect due to Watson ...
She heard Ron making fun of her. Hermione was crying in the girls bathroom during the first book because Ron Weasley was making fun of her and insulting her terribly.
Ron never casts Avada Kedavra at Nagini in the books. What if Nagini was not killed by the time of the duel between Harry and Voldemort? The curse would rebound, just the same as the events unfold in Deathly Hallows. However, Tom Riddle's body wouldn't hit the ground.
Ron thinks quickly and is able to put him back under a spell. But the goblin ends up being killed by the dragon guarding the vaults - meaning Ron has blood on his hands.
He actually asked the Sorting Hat to place him in Hufflepuff, as he was intimidated by Gryffindor's reputation for bravery, but the Sorting Hat didn't agree.
You are sorted into a house based on what you value, not the traits you posses. Percy valued the Gryffindor traits and therefore was sorted into Gryffindor.
In the end, Ron sacrificed himself to the white queen to allow Harry to checkmate the opposing king. It was unknown how Quirinus Quirrell/Voldemort managed to bypass the chessboard.
The Horcrux affected all three of them equally but Ron's delicate condition prompted him to leave. He had more going against him than the other two. Harry and Hermione had already faced their fears.
But it was the mead that was poisoned). Ron was given an antidote to the Love Potion he inadvertently took, however, it was his taking a mouthful of poisoned mead that threatened his life.
The Disarming Charm became Harry Potter's signature spell, and it notably caused the final defeat of Lord Voldemort during the Battle of Hogwarts by rebounding his Killing Curse, because the Elder Wand recognised Harry as its master through the spell connection, and thus strengthened the Disarming Charm to the point ...
But when Ron and Hermione are about to die by Nagini, Ron casts the killing curse as a last resort and it simply rebounds off Nagini as it was nothing.
Peter Pettigrew (a.k.a. Wormtail) is one of two Death Eaters known to have been in a House other than Slytherin (Gryffindor) while at Hogwarts. There, he was a close friend of Sirius Black, James Potter, and Remus Lupin, although he was the least intelligent and least talented of the group.
He didn't want to be a Death Eater, once he realized what being a Death Eater truly meant. He didn't want to be on Voldemort's side, once he came to truly understand what Voldemort stood for. I don't think Draco was inherently a bad person.
It is unknown how Ron reacted when Lavender was killed by Fenrir Greyback, although when he saw her being savaged, Ron was clearly horrified and concerned but Hermione beat him to saving Lavender. Considering this, it is likely Ron at least was saddened by her death.
It was confirmed on Pottermore that Hermione was also a bit of a Hatstall, as the Sorting Hat saw the potential for her to be both Ravenclaw and Gryffindor. In the end, Gryffindor won out, and it's possible that Hermione wanted to be seen for being brave more than for her intelligence.
The three become a tight-knit group, with Ron and Hermione bickering a lot and showing signs of romantic interest in each other, culminating in their fourth year when Ron is jealous of Hermione's date and later boyfriend, despite Hermione wanting to go with Ron.
