The rest of the A/N is at the end but I belieave this should be at the beginning.

Its crackfick or slight crack I definitely don't take it serious.

Neville is the BWL

James and Lily are alive

No Voldemort after the first time when he got blown up by Neville.

Harry teaches the Patronus

Harry didn't know it was possible for a person to show so many emotions at the same time but Daphne was proving him wrong. She was beaming because she finally managed to cast a corporeal patronus, she was all red because of the form her patronus took and she was annoyed because he was laughing at the form.

It all started two weeks after the beginning of their fifth at Hogwarts he was leaving after a particular difficult potions class, thank Merlin his mother was willing to give him tips on how to brew or he would be screwed all because Snape hated his guts, when he heard someone calling him.

"Harry"- he looked behind him and saw Daphne approaching, he stopped and his friends stopped too, it was not usual for the two of them to talk, everybody knew they were acquaintances, their sisters were close to each other and so were their mothers that friendship coming from their own time at Hogwarts

"May I talk to you?" Daphne said and glancing at his friends who were looking at her with suspicion,"in private" she added.

Not unusual considering she was a Slytherin and they were all aware that the two houses did not get along, not that it stopped their friendship, Harry made it clear the first time someone showed to have a problem with him having friends at other houses, during their first year that he would not let anyone stop him from making friends because of Hogwarts houses, something he learned from his mother, and that he knew Daphne for years already anyway even if they were really close but friends anyway, not like their sisters anyway. That particular rant of him came to be useful when his sister was sorted in Slytherin.

"Yeah, sure, go on guys I'll catch up with you later" he said and turned to look at her, "What class you have now?"

"Transfiguration" was her answer

"Ok, I have a free period let me escort you there and we can talk then" and the two of them took off to the transfiguration class.

After some small talk, mostly about classes, he finally asked "So what you need?"

"Well I heard your sister talking to Astoria that you spend most of your summer learning the patronus charm, is it true?" He would need to have a talk with Sophia, his sister, about not gossiping in the common room where everyone could listen, not that he cared that Daphne heard but it made him wonder if someone else also heard,

Apparently reading his thoughts she said "You shouldn't worry the three of us were alone and I just happened to be nearby because I was doing some homework." Well that eased some of his worries at least.

"Yeah and it was one of the most difficult charms I have ever learned" It really was, he was really good with charms, much like his mother and the patronus took him around two months to learn, his taking the form of a Formosan odd-scaled snake, according to Hagrid at least.

"Could you.." he looked at her and saw that she was looking somewhat nervous at him, she made a determined face and said "Would you be willing to teach me?"

"Well, sure I don't mind but I'll say this now, it will take time a lot of time so you will have to be patient, it's not something you will learn in a couple of hours or even a week, it took me two months to learn how to cast it and I had mom, who is a charm's mistress to teach me" He was looking at her while he said that and when he finished he had that same determined face again and said "Don't worry I don't mind that it takes some time as long as I can learn it"

"Good, well here we are" He said and Daphne realized that they had reached their destination, which was the transfiguration class.

"Meet me at this abandoned classroom" he said pointing to the room in front of the transfiguration class. "This saturday after dinner and we can begin"

"See you Daphne"

"See you" she said with a soft smile on her face, something he knew was rare to happen especially at Hogwarts, there was a reason she was called the Ice Queen after all.

Fast forward a couple of months, after a lot of training and even more frustration Daphne finally did it, on the day before they were to leave for the winter holidays, she insisted on one last class because she was sure that she was close.

Harry knew of course that Daphne had a slightly, maybe a little more than slightly, obsession with ice cream. She could eat bowls of the stuff and never get full, on the occasions that their families would get together to have dinner or lunch or something like that it had to have ice cream for dessert or she would go apocalyptic.

That being said it brings us here to the moment that he was laughing and she was beaming, all red and annoyed at the same time, he could never in his wildest dream believe that a patronus could take that form, that being of a Vanillish, a type of ice creature who took the form of all the things, an ice cream, according to the rumours it was a spirit who possessed ice creams and went to haunt people who did not like said dessert it was also very friendly for those who liked it.

"It's not funny" said Daphne in a slight growl, she started walking toward him, that made him stop laughing, she could be scary.

"Yes it is, oh Merlin just wait until your sister sees it" if it was possible she got even more red, Astoria would be merciless in her teasing and they both knew it.

"Well you will not be telling her or I'll gut you" she was really close now and all he could do was nod, he liked to live thank you very much. "Good" was all she said.

Then she beamed at him again "Thank you Harry" and suddenly she was hugging really tight and when he managed to look at her face he saw her smile and boy did she have a pretty smile.

She got on her tiptoes and bent forward slightly and gave him a soft kiss. It was his turn to get all red. He couldn't deny that he enjoyed the time they got to spend together, more than they would usually spend at Hogwarts anyway, and he might have developed a small crush on his childhood friend.

"You will be taking me to Diagon Alley this holiday won't you Harry?", He nodded once and she smiled.

"And you will buy me anything I want from Florean Fortescue's Ice Cream Parlour right?" He laughed and said "Of course"

When they were leaving the classroom he said "I wonder if a patronus can eat and if yours can eat ice cream" Laughing at his own joke he once again got really nervous when she turned to him sharply and gave that annoyed look again.

"Don't worry if it can't, I'll eat for the both of us" Was all she said, he gave her a smile and a fond look.

A/N

I own nothing.

English is not my first language so i'm sorry for any mistake, considreing I wrote this on a diferent document i dont know how formatation will look like.

This as you imagine is a little crossover with Pokemon (if you don't know what a Vanillish looks like just google it)

Daphne's obsession with ice cream comes from the fic "Ice Cream" By Andrius, check it out, is pure gold.
