Bloom, Harry, Ron, and Hermione join Fred and Percy, who are dueling a Death-Eater each.
The hood on the one Percy is fighting slips, revealing it's the current Minister of Magic. Percy hits him with a Sea-Urchin Jinx, saying "Consider this my resignation."
Bloom blasts the one Fred is fighting, sending him onto his back and smoking from his robes.
An explosion happens right next to them, but Bloom makes a shield around them all.
Fred mutters "Bloody hell, glad I've never been on your bad side like this Bloom."
"Yeah, no kidding."
Percy says "Sorry about everything again!"
"Consider this my apology for yelling at you in the Burrow! Your apology can be surviving!"
Acromantulas climb through the massive hole, but Bloom blasts them back for now.
Bloom slips into Voldemort's mind, completely unnoticed by him, and sees him at the Shrieking Shack. She's as silent as a breath of wind when it comes to mental abilities, you wouldn't even know she's there until she spoke to you - or did something she wouldn't normally do, control you for instance.
Bloom yells "He's in the Shrieking Shack! Lucius Malfoy is bringing Snape to him!"
They hurtle down the stairs, which Hermione spells to become a chute, and go through the tapestry at the bottom - and then Harry turns the tapestry to stone, making for a much harder landing for the Death-Eaters coming for them.
Bloom yells "GO! I'll keep fighting here!" They spot Professor McGonagall leading a group of desks in a charge, and Bloom flies past and joins the fighting.
Ron, Harry, and Hermione put the Invisibility Cloak on, and charge down the stairs and into a battle-filled corridor.
Bloom clears the path for them, blasting Death-Eaters to the ground with one shot each and the tide quickly turns in Hogwarts's favor.
They all get to the Courtyard, and find there's even more fighting going on here.
Draco is pleading with a Death-Eater that he's on their side, until the Death-Eater gets grabbed at the back of his robes and thrown hard into the fray below by Bloom - who's in the middle of backflips from her momentum. Draco stares at her dumbfoundedly, until she points her wand down below and hits a group of Death-Eaters with a fireball from above.
Neville Longbottom comes out with his grandmother, carrying Venomous Tentacula - which are more than happy to attack the invading forces.
Harry, Ron, and Hermione are making their way through the crowd, hitting Death-Eaters with spells left and right, and two bodies fall form the sky.
Fenrir Greyback pounces on one, Lavender Brown, and Hermione hits him with a Repulso spell - and then he's hit by Professor Trelawny with a crystal orb in a tennis serving motion.
Fyra is flying through the air with Bloom, singing her song that fills Hogwarts's defenders with courage and hope and strikes fear into the Death-Eaters - and then they all catch sight of Bloom and their fear nearly triples with she catches fire and lands to keep fighting.
Slytherin's Hourglass is broken and the emeralds are spilling everywhere - and then they start quivering when Bloom sees them, and become projectile missiles for her. About twenty Death-Eaters in sight suddenly die because of now-red emeralds and holes in their heads or throats.
Hogwarts's defenders cheer and keep fighting with renewed spirit, until a giant comes out of nowhere. It's on Voldemort's side, but they have Grawp on theirs.
The two giants fight savagely, and everyone scrambles to get out of the way of them.
Hagrid was in the crowd before, but he vanishes in a swarm of Acromantulas when he yells at people not to hurt them.
A mass of Dementors glides towards Harry, Ron, and Hermione, sucking away at their happiness.
Harry almost welcomes the thought of the Dementor's Kiss right then, until Bloom bursts into view and incinerates them all.
She kisses harry, and says "Don't you dare give up on me now, Harry. We're winning, and I'm not going to end this fight only to find your dead because you want the horrible series of events to end early."
Harry nods, and Ron and Hermione smirk. "That goes for you two as well - but I'm not kissing either of you. Kiss each other if you need a happiness-boost."
She flies off back into the fight, and the three friends sprint to the Whomping Willow.
Ron groans, and asks "Where's Bloom when you need her?"
Hermione says "I think the rest of Hogwarts needs her a bit more than we do. There's a knot that paralyzes the branches."
She floats a branch up and jams it into the knot perfectly.
They crawl into the passage, and Harry puts his cloak on and extinguishes his wand before they get into the Shack.
They can hear voices from the room directly in front of them, and Harry can see through a crack between the box muffling the sounds and the wall.
Nagini, Voldemort's snake, is in a glowing bubble of protection and there's a long, white hand holding Dumbledore's wand.
Snape is there as well, and says the castle's resistance is crumbling. Voldemort tells him there's no need for him to go back into the battle, and Snape offers to bring Harry back to the Shack.
A muscle in Harry's jaw tightens in anger, he really wishes Bloom were here right now. Voldemort declines, saying Harry will come to him as he'll hate watching his friends die when turning himself in is the way to stop it.
He's ordered his Death-Eaters to kill as many of his friends, particularly Bloom, as they want, but Harry is to be captured alive.
Snape offers once again to bring Harry to the shack, but Voldemort refuses again and changes the subject to his wands.
His own wand, and Lucius Malfoy's wand, were both incapable of killing Harry, so he found the Elder Wand - one of the three Deathly Hallows. It's supposed to possess legendary powers, powers only it's true master can activate. Dumbledore was the previous master, and it was sealed in his grave with him.
Voldemort didn't understand until recently why the wand showed none of its legendary powers when he used it though, but now he thinks he has an answer. The wand is said to only recognize a new master when the old one is defeated - Snape killed Dumbledore, so Voldemort regrettably has to kill Snape.
He brings Nagini's protective bubble over to Snape's head, and orders Nagini in Parseltongue to bite Snape.
She does, biting his neck hard. Voldemort leaves the Shack at that, leaving Snape to die from bleeding out from his neck.
As soon as Voldemort is gone, Harry floats the box out of the way and enters the room while Ron and Hermione are sitting there in shock.
Harry has no idea what he is supposed to be feeling or doing, as he kneels by his old Potions professor, but Snape's clearly feeling total shock and relief.
He whispers "Take it…Potter..."
Silvery-blue light starts drifting from his face, and Harry conjures a bottle to capture the memories Snape's giving him. When the bottle is full, Snape dies in moments.
They go back to Hogwarts, just as Voldemort's voice rings out and calls for an hour-long armistice.
"You have one hour. Dispose of your dead with dignity. Treat your injured."
When they get back, they see Fyra and Bloom flying around and glowing blue briefly before moving on.
There are mass amounts of bodies - but they're mostly Death-Eaters, Bloom really turned the tide fast every time she entered a battle.
As she lands next to another injured person, she puts her hands on their chest and glows blue for an instant - they get back up when she flies off.
Hermione grins, and says "Something tells me Voldemort might regret giving us an hour to treat our wounded."
Harry asks "Can you guys help her? I need to see what Snape wanted to show me."
Harry's ashamed at the damage he's caused, but Bloom would say it's not his fault - he didn't order the attack on Hogwarts, he isn't to blame. He feels he is though, and runs to the Headmaster's office before anyone else can see him.
Thankfully, Sirius, Remus, and Nymphadora are alright, Bloom helped them with their duels when she saw them - but there are still bodies of defenders of Hogwarts.
Harry pours Snape's memories into the Pensieve, wanting to escape his own thoughts for a while by any means. Nothing, even memories of Snape's life, could be as bad as what's in his head at the moment.
He sees a very young Snape watching Lily and Petunia - Lily's showing Petunia tricks she can do, magic, and tells her she's a witch.
Lily's insulted at being called such, as it's an insult among Muggles, and leaves with Petunia.
The next memory shows Snape telling Lily about magic and Hogwarts - his own parents are fighting, meaning he didn't exactly have the best home life. Petunia appears and insults Snape, and a tree branch breaks off and hits Petunia on the head. Lily leaves after accusing Snape of breaking the branch, but Snape's confused about the fallen branch.
The next memory shows Snape finding a compartment with Lily and two boys - James Potter and Sirius Black. He wants Lily to be in Slytherin, but James and Sirius are scornful of the House. Lily leaves with Snape to find another compartment, but the next scene shows Lily being Sorted into Gryffindor with James, Sirius, Remus, and Peter Pettigrew while Snape is Sorted into Slytherin.
More memories show Snape and Lily arguing and making up when Lily calls James an arrogant toerag one year, but later them not making up after Snape calls Lily a Mudblood but then regrets it later and tries to apologize to her outside Gryffindor Common Room. She won't forgive him, and is fed up with him - he has friends with Death-Eater intentions and she thinks he's going down that route as well.
Harry then learns that Snape revealed the Prophecy to Voldemort not knowing it was about his family, then begged Dumbledore to protect them when he realized who it referred to - after asking Voldemort to spare Lily, but was still afraid for her safety. They were placed under the Fidelius Charm, but were betrayed by Peter Pettigrew shortly after.
Snape felt responsible for Lily's death, and then reluctantly promised to protect Harry after making Dumbledore promise to never reveal that he's protecting James Potter's son to anyone. Harry also saw Snape getting bullied by James and Sirius, so he can understand why Snape would resent that part.
Snape was playing a dangerous game, feeding specific information from Dumbledore to Voldemort while telling Dumbledore all he knew of the Death-Eater's activities and protecting Harry from behind the scenes.
Dumbledore's hand had started to wither because of a powerful curse on the Ring Voldemort used for a Horcrux, and it would've killed him soon enough anyway - Snape was able to slow it, but Dumbledore knew Draco had been ordered to kill him and made Snape promise to do it instead to spare Draco's soul damage; and Snape's would be fine, as a planned mercy-killing was different and had no damage or evil intent for a human's soul.
Then, it's revealed that Harry is an unintentional pseudo-Horcrux of Voldemort's - formed when Voldemort died in the attempt to kill him. Nagini is likely a Horcrux now as well, which explains the constant protection from Voldemort.
Snape also helped with other Battles during the year, covering his tracks so nothing could ever be traced back to him.
AN: And, well, that sucks for Harry and Bloom. Yeah, they didn't know it was Horcruxes until year six - but Dumbledore really should've told them the part about Harry being an accidental Horcrux, maybe Bloom could've done something about it that wouldn't result in Harry's death. Harry thought all this time he might have had a chance at a normal life after Snake-Face was dead, now he realizes he doesn't get a future. Makes the last six years of schoolwork seem almost cruel, if you think about it.
