MORE TONKS. She's clumsy, funny, and creative with her hair choices. Sure, she wasn't exactly a walk-on role, but we definitely didn't get enough of her. I mean? We got so little of her romance with Lupin that it felt like she was tricking him into marrying her against his will? I would like a detective-style TV show following the adventures of cool punk Auror Nymphadora Tonks, and her will-they-won't-they relationship with the ruggedly handsome Remus Lupin.

Rowling has shared Dean's backstory with the fans, but almost none of that made it into the books. There was all this stuff about his father being a secret wizard, and being murdered by Death Eaters, and his muggle mother never finding out, and Dean's quest for self discovery...and all of it was cut. Anyway, Dean's a talented artist, he dated Ginny, he's definitely hooking up with Seamus, and we didn't get enough of him.

C'mon, Jo! A whole subplot about a Death Eater betraying Lord Voldemort and we get almost none of it? It would have been fun to get just a teensy bit more info on one of the most pivotal plot points in the entire book. No pensieve flashback to Regulus at Hogwarts? No drama where Regulus used to date a Weasley cousin or anything? Really?

Lee Jordan was just a ton of fun. He was Fred and George's best friend, he had the best quidditch commentary and...that's kind of all we know about him. But he was hilarious and we wanted more! Did he go on to replace Ludo Bagman after the war was over? I'm going to privately believe that he did, and that he's commentating at the World Cup right now.

The most enigmatic Weasley, by far. Where was Charlie? What's his deal? Why is he seemingly the only wizard in the universe who never got married? (I'm not saying that everyone has to get married all the time, just that Rowling seems to love marrying her characters to each other.) We got to know Bill a bit in the later books, but we still know very little about the second oldest Weasley brother, except that he's good with dragons.

Tonks' mom didn't get to play much of an active role in the books, even though she had one of the most interesting stories. She's the sister of Bellatrix and Narcissa, but she was kicked off the family tree for marrying the muggle-born Ted Tonks. We never even got to see all three sisters in the room together! We didn't get a screaming match over the dinner table! More family drama, please?

The Grey Lady, or the ghost of Helena Ravenclaw, did get her turn in the spotlight in the seventh book. But it would have been fun to get just a few more hints about her tragic backstory and her connection to Voldy before she swooped in for an exposition dump and then went drifting off again. Also, now I need to know the Fat Friar's sob story, too, because it seems like all the Hogwarts ghosts have one.

Why so little Angelina? She was the one who called out Oliver Wood for being sexist all the time, ended up as captain of the Gryffindor Quidditch team, and married George Weasley after the war was won (even though she went to wizard prom with Fred). She was funny and fierce and not in the books enough. Surely she and Ginny would have been cool Quidditch friends or something?

We got lots more Fleur in the later books, but only the tiniest bit of Viktor (and even then, he rolled up to drop some exposition and be sad about Hermione). It would have been fun to get some more Krum in there...like, did he get attacked by Death Eaters at Bill and Fleur's wedding and then just...go home to Bulgaria? I feel like you could have been more of a help in book seven, Vick.

No offense to the Golden Trio, but... it sounds like the Marauders had way more fun in high school. And all we get is that freaking awesome map, a few cool stories, and one measly flashback of Harry's dad being a big jerk. Where is our fun teen rom-com about the Marauders turning into animals, getting in McGonagall's hair, and having a wild spring break? Where? That's all we want, Jo!

OK, honestly this one is less out of a sense of "that character was so fun!" and more out of a sense of morbid curiosity. Really, Granger parents? You're 100% cool with your daughter going to witch school in Scotland and basically never seeing you again? That does not seem like the behavior of ordinary dentists. Like, Hermione is frequently with Harry and Ron for the holidays. Did she ever even go get her parents back from Australia? Did they forgive her for wiping their memories? Do they know that she's the Minister of Magic now? I need more of the Granger parents because I need answers.
