Characters who seem mis-sorted

Even if Hermione might seem mis sorted but obviously she was sorted into the same house as Harry and Ron so the they way they could become closer friends, and even the eventually relationship between Ron and Hermione. Outside of Gryffindor when did you really see Harry Potter, Ron Weasley and Hermione Granger socialize with their classmates in their other houses, other then Luna Lovegood of course? And of course Harry Potter did have his rivalry with Draco Malfoy. Most the the time they spent time together. Did Professor Trelawney not think she was the brightest of her class, one professional of course didn't was Professional Severus Snape. And he didn't like her at all and one point cause her something of a know-it-all or asks if she likes being it. I am surprised you don't think the Harry Potter is mis-sorted as well.

When you think about it, Percy can be seen as a more interesting character than what it might seem like he is at just the first glance. The rest of the Weasley family were typical Gryffindors: brave people, who were not afraid to defy the conventions or even fight in wars. And we know that at least five out of the seven siblings were great Quidditch players. Percy though was always the outsider, who never was able to fit in with his own family. But I guess that he had some desire to change that, and that is why he was sorted into the same house as the rest of the Weasleys. But he soon realized that he simply was too different from them, so he put his mind on getting good grades in school and getting a good career at the ministry instead. Which wouldn't have been a bad thing, except for that he had a big fight with Arthur, accusing him of ruining the family's prospects with his excentric ways, and took a three year long break from his family. And that sounds terrible, and it made even Harry (who by the way was another typical Gryffindor and a great Quidditch player, mind you) decide that Percy had always been his least favorite out of Ron's brothers. But we should remember that Percy only said those things to his own father after nineteen years of not understanding his family. I guess that he had simply grown tired of trying to fit in with them and had to find his own path in life, so he propbably needed that break from his family to find himself and see what was right and wrong...

And as for that weird letter to Ron, where Percy asked him to stop being friends with Harry and confide in Umbridge, it too makes much more sense if you put yourself in Percy's situation at the time. True, he should have known that Harry wasn't as bad as some people said he was. But at this point in his life, Percy was trying to find his own way and break away from the "bad" influence of his excentric family. And to him, Harry would have represented everything that he now was trying to leave behind. Maybe he was also jealous of how Harry fitted better in with his brothers than what he did? And as for what he said about Umbridge, Percy probably didn't realize what a monster she was. He had only seen her as a fellow devoted ministry employee, who did what she felt was best for the whole wizard community. He had no idea that Harry and Ron already had seen too much of her evil sides, that this woman gladly tortured students for the kicks... And also, that letter must also have been some misguided attempt from Percy to connect with at least one of his brothers. He hoped that now that Ron had become a prefect, he would prefer to start "playing by the rules" and being ambitious just like him. But the way things were at the time, that was never going to happen...

Percy did return to his family in the end though, after he finally had understood the gravity of his mistakes. So there is a golden lining to this story, after all. (He would have returned even earlier though, if it had not been for that the twins and Ginny would not even let him stay on Christmas Eve and celebrate Christmas with the family).
