She makes a friend in her year that she partners with during classes. Yavonne will go on to be a wand maker.

The twins are going to the quidditch try outs and Jasmine tags along. There are a lot trying out. As the twins go wait their turn,Viggo sees her and runs over to her. He has a quidditch robe on. She's surprised because she didn't know he was on the team. He's surprised too and before she can get her question in, he scolds her for coming down, thinking she's going to try out. Their mom doesn't like quidditch, it's one of the only wizard things she couldn't accept she said it was too dangerous. So they were only allowed to use the little kid brooms.
She explains that she's just here to cheer on her friends. And asks what the heck he's doing. He admits he's been on the team since his 3rd year, and has kept it secret from everyone back home.
She says he has to get her treats from honeydukes in order for her not to tell mom.

She watches and he's a very good chaser. And she claps when Fred and George's turn happens. And then tries to hold in a gasp when George manages to get a bludger at Viggo.

She hears more about Harry Potter in her second year from the twins after Ron says he's become friends with him.

She gets up to a lot of trouble with the twins. Riling up peeves, setting dungbombs, luring mrs Norris into traps. They never get caught in the act because of the marauders map. Although many of the professors suspect them.

She sneaks into the forbidden forest for the first time, goading the twins into following her. They get caught. But it doesn't stop her from going back another time later that year. She makes friends with some of the smaller friendlier creatures. She sees an ominous shadow and that night, she has a dream of a shadowy man standing in front of a mirror.

In summer after her second year, she invites the twins over. Mr Weasley bring them and gets into a long conversation with Colette as she lived in the muggle world. Jasmine sneaks them to the forest. She's only allowed in with an adult. They don't go to far in but they see a lot of smaller creatures and she's able to tell them all about them. Her favorite forest friend is a silver eagle that has feathers that can turn as sharp a a blade when it feels threatened.
Viggo finds them and scolds them.
Fred suggests that they play quidditch but then they find out about keeping it secret. So instead, the three go to Jasmines room and they hatch a prank on Marilla.

Telling Malfoy that her squib mother has more backbone, integrity, than his whole pure blood heritage combined after he insults her mother when she's in her 3rd year.
She tells Viggo and the others in the commen room about her encounter.
She starts care of magical creatures with professor Kettleburn.

She makes a mistake with one of the animals or plants that knocks her out. She has a dream about picking a certain plant and hearing an animal calling that she's never heard before. And she wakes up in the hospital wing.

She spends the summer helping her grandparents tend the forest and they give her some galleons for her effort. She buys a broom.

She's good at quidditch but doesn't try out for her team. She just likes practicing with her brother and Fred and George. Viggo (I think) is in the same year as Oliver Wood. He's still a Chaser.

Her 4th year she has a dream of Voldy but doesn't know it's him. He's standing in front of an angel and is laughing.

Summer before her 5th year, has the Quidditch World Cup. Her American relatives come over to visit. They all, aside from Colette who hates quidditch, takes a port key there and sets up a tent like so many others. They run briefly into the Weasleys. The swan family had purchased a booth which was unfortunately next to the Malfoys.

Her 5th year is the triwizard tournament. That is when Fred asks her to the dance and she starts to think of Fred in a different way. A few weeks later, she gets him alone and she kisses him. They then start to go out. They try to keep it low key in front of George and the others. But there are more and more times Fred makes excuses to meet up with George later. Which is extremely weird cuz they have always done things together. George finds out and is a little peeved but ends up cracking lots of jokes.

Idea: Finds ancient magic that bestows magic onto a squib/muggle either temporarily or permanently turning them into witch/wizard

It's in Peru in a cave behind a waterfall. An old indigenous wizard tribe bred a magical animal that laid an egg to give the magic. It's long like a dragon. Scales on most of it with a feather main going down the spine. The scales and feathers give the temporary magic or make a wizard temporarily more powerful.
Jasmine and Viggo get into an accident where they find the cave after looking for creatures that have saliva that gives wizards stamina. This is her summer before her 6th year. Albus has come to recruit Marlon, Leo, Viggo to the rebanding of the Order and had asked them to go to Peru to help some wizards who were working on a cure for werewolf bites. And jasmine had an intuitive feeling that she needed to go too and remembered that saliva. Viggo agreed that she should go too after her father's arguments.
The creature they find in the cave, jasmine befriends, they can see that it is old and alone and hurt. They find the nest it has been keeping with three eggs. There are writings on the wall and an idol-like temple around where the creature is. Viggo magically copies the scriptures into a journal to bring back and translate. Jasmine doesn't want to leave the creature in its condition and together they coax it into a magical carrying case that shrinks down into a muggle looking pet carrier. They place her eggs in there and she curls around them.

They get the writings translated from some Peru wizards. Viggo tests out what they found out about the feather and scales and the Peru wizards become suspicious. The two have to keep the special creature hidden until they make it back home. Where they reveal to their parents what they found and contemplate if they should test out the other power that was written. Where if a squib cracked open an egg, the creature inside would bond with them and share the magic ability. Colette refuses. (But later changed her mind after Arthur Weasley is attacked during winter)
They bring the mother back to health.

Jasmine has been able to keep her relationship from Viggo and her parents. Marilla has a pretty good idea about it and uses that to bribe Jasmine on things.
Jasmine and Marilla get to stay at Grimwald place for a week before school starts. Colette stays home to care for the magical creature and each day the egg is more tempting.
Then her father walks in on her and Fred kissing and is all flustered at dinner. And somehow the relationship is revealed then. Mrs. Weasley is flustered as well and from then on, she keeps a stricter eye on them.

At the end of her 6th year on the train back to kings cross, she sees Fred and George and they walk over to her. Their family in the background talking to Harry, ron, hermonie. She's impressed with their new dragon skin suits. They spin around her and George says they gotta be snazzy for jazzy. Fred spins her around and wraps her arms around her waist. They are about to kiss and the Marilla makes a gagging sound. George says he's got something for Marilla to give the two some privacy. When Jasmine and Fred step back to hide behind a pillar, a hand grabs the back of both their collars. It's Viggo. She chides him not to disrupt her relationship just because he doesn't have one. And he says that he does actually have one. Great Grandma queenie introduced him to a girl on his visit to America with their mom right after the holidays. (Her mom was contemplating the egg and she wanted to see her American family before the uncertainty of egg hatching.)
Marilla asks why he's there and not their parents. Viggo just shrugs and simply says, he came with the Order. He hurries them on. They all catch up with the rest of the Weasley family. But they are looking Harry. The Vernons had showed up to take Harry home. And some of the Order members are talking to them. After they say their goodbyes, Jasmine says to Viggo that Harry should stay with them. Viggo frowns and said that it had gotten brought up at one of their meeting when Albus visited. Harry must stay with blood relatives for his safety from the dark lord. That's why the Oder had a talk with Vernon.
Summer before her 7th year, her mother cracks the egg. They marvel at the change in Colette who now has magic. They bring her to Olivander under the impression that Jasmine needs a new wand. She passes each want to her mom while Viggo distracts Olivander until Colette finds one that suits her.
They spend a majority of the summer teaching Colette the basics of magic.
But still when out in public, she pretends she's a squib.

Luna mentions a weird creature that is similar, one time to Marilla and Jasmine as they were quietly talking about theirs while out in the grounds.

After her 7th year, she takes a trip with her mom to meet Newt Scamander and brings the magical creature with her two remaining eggs. She had been keeping them in her fathers forest. After explaining everything, Newt is speechless. He says that there were mentions of such a creature but he had never found it.
They also converse on the passing of dumbledore.

Jasmine insists on being a polyjuice copy of Harry during his journey to the weasleys after his tracker turns off. It's one of the only serious fights she's ever had with her parents. They also don't want Viggo. They says that they have enough people to divide up. Leo and Marlon were a pair. Viggo and Jasmine refuse to back down. She is part of the Order now and this is what she can do for him. They both are excellent flyers on brooms. Marking and Leo would only benefit with more eyes and wands. Marlon says nothing is going to happen that they're need those extremes. It's just precautions. They counter, exactly! It's just to transport Harry. Jasmine adds that they can ask the creature for a feather.
Colette sees that she can't change their minds but is still very angry that they feel like they need to be a part of the transport. Jasmine doesn't see her before joining the rest of her family to disaperate. Marilla sees them off and says that she will keep close to Colette to reassure her.

They meet at the designated location to collect the thestrals and then ride under hidden charms to Harry's place. Jasmine and Viggo would be together; Jasmine as Harry. But Marlon and Leo pressure them to both be Harry so that Jasmine would ride with Marlon and Viggo to Leo.
They have a little fun acting out in front of Harry as him. She can tell which is Fred by the way he looks at her. Harry looks exasperated. Jasmine tucks a feather in her pocket and hands one to Viggo.

They take off using brooms. It's chaos. Jasmine and Marlon fling curses. She catches a glimpse of Voldy before they change courses. Death Eaters cast fire at them and her arm starts on fire. Her dad puts it. But then another spell hits homans he's almost knocked off his broom. She jumps up for moment to catch him and push him back on. They reach the barrier and the death eaters pull back. They land. Leo and Viggo were supposed to be right behind them but they never made it. Marlon decides to go back for them, not letting Jasmine come along. He pushes her down with a spell so she lands on the port key just as it activates.
Shes brought to the Weasleys. In her anger she throws the port key. Lupin and Harry walk over to her. She's mumbling about them not arriving. Lupin ask her a question to know that it's actually her. She realizes that she's not Harry anymore. The question is about the time Lupin and her family had dinner and what did she try for the first time there.
She explains vaguely what happened on there end. She's still upset. She asked if all of them made it. Hermonie is there, suggesting she go inside. When she gets in, Mrs Weasley is walks through the entrance and hugs her. She asks if her family came in too. Jasmine explains. Mrs Weasley said she will keep an eye for them and that she should go see the twins.
George is resting on the couch. Fred pacing slowly. He hugs her and they have a short conversation with some humor about George. To which she sees him grin with his eyes closed. Then Hermonie shouts out and her and Fred walk out to see her family entering the gate. Viggo is supporting Leo who is barely standing. And Marlon is moving slowly. Others help them into the house. Marlon found the death eaters surrounding the two, binding them on the ground. They got crucioed. Her father took on them all but it was too much. He got spells at him. Viggo broke his bonds and did such a powerful stunning spell, that it got most of the death eaters. And then they disaparated.
Jasmine had so much anger in her for not being there to help that she was shaking. Fred noticed as he's standing right behind her. The group discusses Moody and the ruined transport. Harry gives a farewell to Moody. Lupin and mr Weasley go to search for moodys body. Mr Weasley fusses over George, Leo and Marlon. Jasmine hasn't looked at Marlon since his first reappearance. Viggo and Marlon go back to the Swan place to see Colette and Marilla. Viggo says he'll bring back potions to help George and Leo. It's too dangerous to bring them to St Mongos now.
Fred puts a hand on Jasmines shoulder and they start to walk out of the room. She notices that Harry Ron hermonie are outside as they pass a window.
She lets out her frustration as they get to his room. They comfort each other. Then she notices all the weird things in the room and he laughs about it, showing her a few of the items. She falls asleep next to him.

She wakes up early and Fred feels her moving. She kisses him good morning and says she's going to talk with her parents.
She makes her way quietly downstairs. She sees George and Leo sleeping in the living room. Just as she's walking out the room, she's pelted with a pillow. It's George. They talk about her staying overnight …
She arrives at the swan place and silent alarms wake her parents. She forgot that those were in place. She had wanted to get cleaned up first. But she talks to them and apologizes for making her mom worry with being in the Order. And she says to her dad that she understands why he did

Colette and Marlon have been helping Half-Bloods and muggle borns out of the country to the United States.

Battle of Hogwarts:
She brings the creature but keeps it hidden. They use some of the scales to help them. She's fighting with Viggo and Marilla when they get attacked. She protegos but as soon as the spell deflates, another blow comes from the side and slashes all three of them, marilla getting the worst. Viggo takes on the two death eaters while jasmine gets marilla back and covers her wound. She jumps back to help Viggo. The death eater left runs off and jasmine follows against Viggos yells.

After voldy gives them a chance to collect wounded and dead, she runs into her dad who's arm is all bloody and is weak. She helps support him back to the great hall. She finds the Weasley family. Percy is just laying Fred's body on the ground. She can't move, still holding her dad. She can hear him mumbling to her. Then his weight is gone. Viggo has him now. He's also very bloody, he's gotten another slash above his eye.
George catches her staring. He disentangles himself from Ginny. His movement allows jasmine to move to them. She kneels down beside Fred. George takes her hand.

When Voldy arrives at the entrance with the rest of the death eaters and a dead Harry, she feels so much anger. The silence spell can't keep them quiet. And then she remembers the creature is still hidden in the clock tower. She calls to it with a low whistle that she had been practicing with it. Then Voldy calls out Neville and the sorting hat scene.
The creature shows up, and jasmine plucks some feathers and scales. She melds them into her skin with a spell. The creature looks at her as if knowing she needed all the power she can get, opens it's mouth. With a now glowing tongue, licks the open wound on her shoulder. Jasmine can feel the power rush into her. She didn't know that the creature could do that. She feels light and her movements are lithe and fast. It's almost as if she could fly.
