I have to agree with the little green Chinese monk. The cameos in the authors were great. Alexander Corvinus was the one that got my attention, and I spotted River Tam as soon as I looked for more, but is Jane Smith a nod to the Dr Who character Sarah Jane Smith, or to Angelina Jolie's character in 'Mr. & Mrs. Smith'?
I like that you are turning into a more full-fledged story what seemed to start life as a humorous one-shot. And those who are being gits and calling you a plagarist (one of the most vile thing one can say to an author - an insult right up there with 'mudblood')? Fook 'em! You know you have permission, you've posted that you have permission, and if they can't read (and most critics obviously can't), then to he11 with them.
Now, to your questions.
Should this story contain lemons (or should it be more of a fade to black scene)?
I like lemons. Limes, grapefuit, and other yummy citrus are also gratefully accepted. Just don't let the men slash them apart before serving.
When should their relationship go to another level? (IE, How far and when?)
Hmm. As the French are much more open about amour, Beaubatons should have separate suites for arranged couples. All students get an epic length version of The Talk, including How To Best Please Your Mate. Of course, the girls are also strongly encouraged to get a contraceptive implant, just in case. This will allow Harry and Fleur to play more freely. Start with kissing and light petting in first year, heavy petting and oral in second, and sex in Harry's third year. I thought originally to say to wait longer, but in Harry's third year, Fleur is 16, and (if my girlfriends in high school were any indication) has been crawling-the-walls horny for the past couple years. And anyone who says that a 13 year old male isn't ready for sex with a 16 year old Veela has never been a 13 year old boy. Harry was ready at 12.
What do you consider over powered Harry?
He's not overpowered until reality starts warping itself around him in response to his subconscious desires.
What do you think should happen at Beauxbatons during the school years (1st, 2nd, and 3rd)?
See your second question above. Also, Harry should immediately make a request to test out of 3rd year classwork, so he can be with Fleur. He should only succeed in those subjects he has been able to practice, i.e. potions, runes, arithmancy, history, etc. Charms, Defense and Transfiguration he should stay in First year, even if he is a bit advanced (he does need some socialization time with kids his age.) A kidnapping attempt would be good, to showcase his and Fleur's training. And of course, the manipulative old bast@rd won't stop trying to get Harry under his thumb. (Maybe he was behind the kidnapping attempt...) Advanced training (Harry's parents knew the prophecy, and told Fleur's parents, who will tell him and start getting him trained), which should, at Harry's insistence, include Fleur, for her own protection (since he can't be in every class with her.) Training should include Occlumency, Legilimency, and animagery. As Harry is only going to Beaubatons to be with Fleur, Dumbles should try to get between Harry and Fleur (maybe he tries to get her raped/pregnant, or set her up, with a little chemical assistance, to be unfaithful to Harry, with a fertility potion to really mess her up.)
Wow. You had to go and ask, didn't you? Now look what you've made me do.
Anyway, thanks for writing a great story for us. I appreciate your efforts to keep us all entertained.
