|Muggles' Guide to Harry Potter - Character|
Katie Bell is a member of Gryffindor House. She is one year ahead of Harry, and plays Chaser for the Gryffindor Quidditch Team.
Role in the Books Edit
When the Gryffindor Quidditch team take to the air for their first match, against Slytherin in November, it turns out that Lee Jordan is the announcer. He identifies the Chasers on both teams who are holding the Quaffle. This is the first time we hear Katie Bell's name, although presumably she has been practicing with Harry and the other members of the Quidditch team since Harry was made Seeker in mid-September.
Katie again plays Quidditch as Chaser for Gryffindor alongside Angelina and Alicia.
With Quidditch being suspended for the Triwizard Tournament, we don't see much of Katie at all.
In the warmup before the first practice of the year, Ron passes the Quaffle to Katie too enthusiastically, and it catches her in the nose. Fred Weasley gives her something small and purple from his robe pocket, saying that it will clear up immediately. It does not, however. When Angelina tells her to do something about it, Fred examines what he has in his robe pocket and appears horrified by what he sees. Shortly afterwards, Angelina stops the practice; Alicia points Harry at Katie, who is being attended by Fred, George, and Angelina. Fred says that she had likely been given a Blood Blisterpod by mistake, and that he and George would take her to the Hospital Wing.
A short while later, horrible weather keeps the students in at break. Peeves is floating overhead in the room, flicking ink balls at the students when Angelina arrives to tell Harry and Ron that the Quidditch team has been re-formed. Peeves manages to hit Katie Bell with an ink ball, and she starts throwing things at him. As the bell rings, Peeves dumps an entire bottle of ink over Katie's head.
Katie plays in the match with Slytherin, a match which ultimately Gryffindor wins, despite Ron's poor Keeping, as Harry catches the Snitch for a final score of 160 to 40. Angelina, Alicia, and Katie then hold Fred back from attacking Draco Malfoy, who is taunting the entire Weasley family, while Harry holds George. When Draco starts insulting Harry's family as well, Harry is unable to restrain himself, and he and George attack Draco, while Fred remains restrained by the three Chasers.
As Harry has been unwillingly reduced to the role of spectator at Quidditch, he no longer interacts with Katie on the pitch. While we can assume that she continues to work with Dumbledore's Army, her work is not singled out on the rest of the story.
Katie Bell again makes the Gryffindor Quidditch team, after pointing out to Harry that she should try out like everyone else; if there is someone better at Chasing than she is, that person should have her spot, friendship shouldn't automatically control team selection.
On a Hogsmeade weekend, she is apparently given a package to give to someone at Hogwarts. The contents of the package turn out to be a necklace that was seen earlier at Borgin and Burkes, which carries a curse. Katie is injured and spends significant time in St. Mungo's Hospital. On her return, she tells Harry that she does not remember anything after walking into the ladies room at The Three Broomsticks, from which Harry concludes that she was put under the Imperius curse.
As she had graduated at the end of the previous year, we would not expect to see Katie return to Hogwarts. She does, however, return for the final battle against the Death Eaters; Harry sees her when he returns to the Room of Requirement after visiting Ravenclaw Tower. We don't hear much of how she acquits herself in battle, though.
Relationships with Other Characters Edit
While Katie does not obsess about Quidditch to the same extent that Oliver Wood, or later Angelina Johnson, does, she still seems to be quite caught up in it. We seldom see her when she is not playing or practicing Quidditch. It would seem that Katie has good relationships with Alicia Spinnet and Angelina Johnson, with whom she played Quidditch for most of her time at Hogwarts, and is generally seen with the two in most of her appearances throughout the series. Another of her good friends is Leanne, who isn't mentioned until the sixth book. Also, there are times that we see her sitting in a corner of the Gryffindor's common room, but generally there is no indication as to who she is sitting with, or what they are doing.
Although Katie Bell has a relatively minor role in the books, she has become a fairly popular character on the internet. In particular, a large amount of fan fiction has been written that pairs her with Oliver Wood. There is nothing in the books that would suggest this, or in fact any, romantic relationship.
