You know, Quidditch is a lot like real life. That might not make sense, but think about it. You've got a Keeper, who stops the other team from scoring points. You've got three Chasers, who try to score points. You've got two Beaters, who try to keep the danger away from the other players. And you've got the Seeker, who steals all the glory from the team.
Quidditch is a team sport, really, and I'm sure the Seeker doesn't mean to steal the glory. But no matter how well the Keepers block, no matter how hard the Beaters hit, no matter how many points the Chasers score, everyone decides that the Seeker is the one who should be praised and respected.
You see, the war is a lot like Quidditch. The Keeper would be Dumbledore, stopping Voldemort from scoring 'points'. The Chasers would be the Order, working together to score 'points' by stopping the Death Eaters. The Beaters would be Hermione, because if a single thing threatens her 'team', she'll be knocking it away, and one angry Hermione is worth twenty Beaters.
And of course, Harry would be the Seeker. Because no matter how well Dumbledore blocks Voldemort, Harry gets the praise for just stopping him for a second. Because no matter how many Death Eaters the Order catches, Harry gets the praise for getting just one of them to spill their secrets. And because no matter how many times Hermione uses her spell knowledge to create a spell to take out any threats, Harry gets the praise for getting the main prize; the Horcruxes.
And it's not fair to the Keepers, Beaters, and Chasers, who work so, so hard, but what's there to do? They just have to live with it.
So all of the other people on the Quidditch team have to get used to Seeker getting all the recognition. It's not fair, it's not just, it's not right. Sally-Anne Perks should have gotten more than a passing mention when she gave up her life so Harry could try out a new spell, one that required the use of a human heart. But she didn't, and thousands of other players died, and everyone praised the Seeker.
But that's how Quidditch is. All the players fly their hearts out, but everyone praises the Seeker.
A/N: I was just really, really bored, and then I think about it, and really, I've never heard anybody throw a "good job!" the way of Oliver or Fred or George, or anyone on the Quidditch team besides Harry Potter. And then I tie that in with the war, and there you have it!
