Some fanfiction authors like to play with the idea of betrayal for the sake of creating drama. So, they might depict the Weasleys as untrustworthy to Harry in their stories. But in the real Potterverse, the Weasleys have always been there for Harry. They welcomed him into their family, provided him with a home away from the Dursleys, and fought alongside him in many battles. Their loyalty is a cornerstone of the series, and these fanfiction ideas are just a deviation from that.
Well, it could be that in those fanfictions, the writer is exploring an alternate universe concept. They might rewrite the Weasleys' characters to be more self - centered or having hidden motives that Harry discovers over time. But this goes against the general perception of the Weasleys in the official Harry Potter series where they are loving and trustworthy.
It could be that in the fanfiction, a dark wizard has somehow influenced the Weasleys' actions without their knowledge. Harry, being cautious after all his experiences with the dark side, might misinterpret these changes in their behavior as signs of untrustworthiness. So he doesn't trust them until he figures out what's really going on.
One possible plotline could be that the Weasleys are secretly working for a dark wizard. They pretend to be friendly with Harry but are actually spying on him for the enemy. Another could be that they have a family secret that would put Harry in danger if he trusts them too much, like a curse in their bloodline that could harm Harry.
Maybe he has been betrayed too many times in the past. For example, in the original story, some so - called friends or allies might have let him down, and this experience makes him overly cautious in the fanfiction.
Another reason could be outside influence. If there were dark forces trying to drive a wedge between Harry and the Weasleys, they might plant false ideas in Harry's mind. This could make Harry question the Weasleys' loyalty, even though they are truly his friends.
Harry Potter has lived through his own real experiences in the wizarding world. Fanfiction is often just the creative interpretations of fans. It could distort the true nature of his relationships, the events he's been through, and the values of the wizarding world. So, he doesn't blindly trust it. For example, some fanfiction might change the way his friendships are portrayed, which doesn't align with his real experiences.
In some fanfiction, Harry might not trust Dumbledore because the author wants to explore different power dynamics. Maybe they show Dumbledore keeping too many secrets, like about Harry's past or the true nature of the threats he faces. This secrecy can make Harry feel manipulated and thus lead to a lack of trust.
In some fanfiction, the author might create a plot where Harry has been betrayed before. So, he has trust issues even with his friends. For example, if he was tricked by someone who seemed like a friend in the past, it could make him more cautious and less trusting in new situations with his real friends.
In the original story, the Weasleys are like a second family to Harry. They are his closest allies and friends. But in this fanfiction, the distrust changes the dynamic completely. It goes against the warm, loving relationship they have in the original.
Perhaps in this fanfiction, Snape has proven himself to Harry in some extraordinary way. Maybe he has saved Harry's life multiple times or has shown his true loyalties that were hidden in the original story. It could also be that Snape has some special connection with Harry that makes Harry trust him unconditionally.
Most likely. The 'Harry Potter' series is all about friendship and family, and the Weasleys are like a second family to Harry. To have him kill them is a huge deviation from what fans expect and cherish about the story.
