Harry, Ron, and Hermione have just been taken inside the Hog's Head Inn in Hogsmeade, and they can hear the man who helped them out, Professor Dumbledore's brother, walking back up the stairs when the Caterwauling Charm goes off again.
Harry is suddenly stunned into silence when he feels a familiar feeling - one he hasn't felt since last year.
As Hermione peeks out the window, she sees a bunch of Dementors and Death-Eaters surge forward, only to get thrown backwards - and the Dementor's obliterated - by a wave of fire.
She stares for a moment, then realizes what it means and starts jumping excitedly.
Ron asks "What is it?"
"The Death-Eaters just got knocked out and the Dementors got obliterated by a wave of bloody fire that came from a person's body! There's only one person that can do that!"
Ron is stunned, until Harry runs down the stairs two at a time - just in time for them to hear a banging on the door.
It's loud, hard, and insistent, and Aberforth Dumbledore opens the door just in time for them to get downstairs.
Bloom is standing in the doorway, looking like she's gotten a lot of sun with her golden suntan while they've been running around trying to find Horcruxes and not get arrested and killed.
Harry sweeps her into a massive hug, which Hermione and Ron soon join in on.
Hermione says "Bloody hell. Bloom, next time your old headmistress decides to need to get stronger, don't take bloody well forever about it!"
Bloom says "Sorry Hermione. Training took longer than anyone expected. On the bright side, I've now done the impossible how many times?"
Harry asks "You…"
"Got my Enchantix, don't ask me how. I don't know, but I do know I'm going to find Snake-Face and give him a body-ful of fire."
They catch Bloom up on everything that's happened, all the things they've done - they had to fight Umbridge again, and she had the real locket.
They broke into Gringotts bank earlier today, and stole the Hufflepuff cup from Bellatrix Lestrange's vault then rode out of the bank on a half-blind dragon.
Ron asks "And you've been what? Running around through a forest by your description."
"Ron, I nearly got turned into lunch several times!"
Harry kisses her, then breaks it and says "Sorry, needed to do that." Bloom smiles, then kisses him back for a minute.
Ron clears his throat, and says "I know you just got back, but please cut the snogging for now. We've got more important things to worry about."
Bloom asks "Is everyone still alive? Sirius, Remus, the rest of the Order?"
Ron says "Most of them. Sirius and Remus are for sure, I'm pretty sure Tonks is as well. She and Professor Lupin have a kid now, by the way."
Bloom's jaw drops in shock, and then she says "Well, let's make sure he grows up in a better world than this one!"
Aberforth tells them there's only one way back into Hogwarts now, and the picture of his sister, Ariana, disappears for a bit.
When she comes back, the painting swings open to reveal a heavily beaten and bruised Neville.
He gives out a shout of excitement when he sees them though, and jumps for joy then regrets it.
Bloom says "Neville, sit down now. I'll heal you, you tell us what's been happening at Hogwarts."
He does, and they discover its worse than they could have imagined.
DADA class is basically just Dark Arts class now, Muggle Studies is mandatory and is teaching everyone to hate muggles and muggle-borns, it's not really Hogwarts anymore.
Voldemort took control of the school and the Ministry when Rufus Scrimgeour was killed - he died because he wouldn't tell them where Harry was.
Bloom feels bad about yelling at him now, and says "Guess he wasn't such a bad Minister after all, huh Harry?"
Harry nods grimly, and then Neville leads them back to the school, they can all guess where they're going to end up.
Sure enough, they come out into the Room of Requirement - and find it's jammed with students of all houses except Slytherin.
Most of Gryffindor, Hufflepuff, and Ravenclaw is there, and all of them get up and start cheering when they see Harry, Ron, and Hermione.
The reaction is deafening when Bloom comes out though, and they all pick the four friends up on their shoulders now. Fyra comes flying over, and Bloom hugs her gratefully.
When they finally get put back on the ground, they hear how the new teachers, Amycus and Alecto Carrow are in charge of punishing students - and neither they nor Snape can get into the Room of Requirement.
The DA has been hiding out in here for two weeks now, and the passage to the Hog's Head Inn has been appearing as students get hungry - the room can't make food, unfortunately.
Fyra's been a huge help healing people and boosting spirits, and Neville's become the leader of the group, along with Ginny and Luna as sort of Lieutenants.
They all say they'll absolutely help with finding whatever it is they need to find, and Bloom says "Alright, but first let's get everybody healed first."
She transforms, much to everyone's amazement - and Harry's mind-melting - and then she starts glowing brightly and earns a new transformation.
She's in a bright blue and pink top and skirt, has even larger wings, and her hair is held in place by itself in a kind of braid-tiara.
Neville asks "Is this why you disappeared last year? Nobody saw you on the train."
"Yeah, the last transformation was. And I just got a whole lot stronger." She says a spell under her breath, and then everyone's injuries are healed.
Some kids are staring at her in shock, and Lavender asks "What exactly are you? And, is this why you're the strongest kid to ever go here?"
"I'm a fairy, Lavender. And, yes, this is why I'm so strong. Now, everyone, we've got a Death-Eater regime to overthrow! Everybody got the coins I spelled up two years ago?"
They all hold up a coin each, and Bloom says "Good, don't lose them. They've got protection spells on them, to keep you safe and let you know if we need you. Now, let's go stop some evil!"
More and more DA members, like the Weasley twins and other graduated students, arrive by the tunnel, and stop dead when they see Bloom.
She smirks at their reactions, and says "Don't crowd the entrance people! More coming in behind you!"
Fred and George are seriously stunned speechless, and Bloom teasingly asks "What? You've known me for years and now you stop and stare?"
Ron says "Yeah, I know. Roll with it guys."
Twenty minutes later, Bloom's told everyone they're going down to the Great Hall - they're going to win this tonight.
She's already sent Fyra to Professor McGonagall with a message to get everyone ready to evacuate if it becomes necessary.
Ron and Hermione are going to destroy the two Horcruxes they already have, she and Harry are going to find Rowena Ravenclaw's Diadem and destroy it, and the Death-Eaters are going down.
They can all guess Voldemort would have used the Diadem as a Horcrux, that's the way he is - arrogant, only willing to use such an important and iconic item for a Horcrux.
They march out, after Bloom does a spell on herself to give them all an edge - the DA members can see her, but their enemies won't be able to until she gets their attention.
They encounter Alecto Carrow, who is about to start punishing all of them when Bloom clears her throat behind the woman.
Harry's under his Invisibility cloak, and smirks when Carrow tries to use the Imperious curse on Bloom - nothing happens, Bloom's too stubborn and strong-willed to be controlled.
As he watches, Bloom blasts Alecto just after she presses her Dark Mark and floats her wand in the air.
The wand explodes after a second, and everyone grins. Neville jokingly asks "Is that what you did to Umbridge's wand?"
"Oh yeah, absolutely."
Amycus and Professor McGonagall come in moments later, and find an unconscious Alecto on the ground.
Amycus decides to blame her summoning of the Dark Lord on the mass of students glaring at him - and then he spits in McGonagall's face when she says won't allow him to put her students in danger.
He then gets decked by Bloom so hard he falls to the ground unconscious and his wand flies up.
Bloom catches it and snaps it in half, then sees Professor McGonagall staring at her with a mixture of joy, shock, and wonder. "Bloom?"
"Hello Professor. Good to see you again. Hope I won't get expelled because I attacked a teacher."
McGonagall breaks out into a grin, and she says "I got your note, where're you headed?"
"To stop this. Lead the way, Professor."
They run into Snape in the Great Hall, along with the rest of the students.
AN: Yeah, Bloom got her Believix. The cartoon said they had to get someone on Earth to believe in fairies, and she transformed in front of nearly a hundred kids - chances are some of them had to believe. Also, the Death-Eaters are very literally toast. Keep reading to find out whether Bloom cooks them well-done or extra-crispy!
