Well, "soon" may have been the optimism speaking out of her.
Because the following week her imprisonment become even harder than before.
It began with uncle Vernon repairing the cracks in the door by hammering thick boards on it and putting a huge padlock before it.
When she later returned after being allowed to use the bathroom, she found him bricking up her window while humming a happy song.
Then at the very next day she found him installing a cat flap into her door while her aunt was removing the pieces of furniture or pictures at the wall, that hadn't fallen down when she accidently almost blasted a hole throw the wall.
Afterwards she wasn't allowed to leave her room anymore.
Now she had to use a bucket that regularly was pushed through the flap and got her food once a day delivered in much the same way.
In the beginning this hardly bothered Rose.
Sure, using the bucket was certainly disgusting, but she had all the time she could ask for to practise and to figure out how she had almost broken through the wall.
She was also certain that the Dursleys couldn't keep this up longer than a week.
Afterwards her suspension at school would end and if there was one thing, she was certain about her aunt and uncle then it was that they hated to have her around.
At least that was what she had told herself until the week had went passed and a bunch of schoolwork was pushed though the flap one morning.
"You are getting home-schooled from now on." Called aunt Petunias voice from the doors other side.
It was at that moment that Rose realized that the Dursleys may actually have planned on keeping her in this small room forever.
This realization caused a strange hollowness inside her.
A hollowness that grew soon into a full-blown panic.
"Aunt Petunia!" She screamed as she hammered against the now far sturdier door.
"What do you mean, I am getting homeschooled?!"
Panic started to seep into her voice.
Would she never again leave this room? This was too much!
She had all the time though that this was just temporary!
Tears started to stream down her face as she continued to bang against the door, begging her aunt to come back, making promises about being obedient, more hard working- all to no avail.
In the end she sunk down to her knees crying desperately.
"Mommy! Please help me! I don't want to die here!" She sobbed uncontrollable, ignoring how little sense her pleads made at this point.
Hours later Rose had managed to calm herself down well enough.
"It's just a door!" She sniffled.
"I almost broke through the wall; I can manage a door."
Slowly she pulled out her journal out of its hiding place under her bed.
Opening the entries about the explosion she had caused; she went through the detailed recount of what she had down back then.
Since back then she had reproduced the effect six more times.
Of course, she made sure to only use the lowest amount of energy she could manage to not cause another incident like before.
These experiments had allowed her two learn a few things about her magic.
For once was that she felt a bit tired whenever she used it.
It wasn't much or even truly relevant, just a little light-headed for a few seconds, before she was alright again.
The other was that no matter how little she used, it still just exploded in all direction when she let her control go.
In the beginning when she still hadn't really managed to control the amount of released power, this had almost caused a second explosion.
Thinking back some of her attempts where a still a bit loud and might have strengthened her uncles resolve to imprison her.
Pulling out the pendant she closed her eyes and concentrated on producing a bit of her power again. This time she didn't tried to take any control of it, just letting it drip out of her a bit just like back then when she had first managed to feel it.
Immediately the behaviour of the pendant changed.
Instead of just rotating endlessly in her end, it pointed now in one specific direction, just before suddenly to jerk around and point into a random different one.
This continued for a while until the last slivers of her magic had faded away again.
Rose pulled up her nose.
No changes.
She hadn't tried increasing the power yet, but she was scared that it would make things worse at this point.
So far, all she managed to do with magic was to blow things up.
She couldn't risk that with the pendant.
At least she had managed to change something with it, perhaps if she could figure out how magic actually worked…
Yeah, that circlet back to her only being able to create explosions.
Why could no one simply tell her how it worked?
…wait didn't Cirilla tell her that she bought it in London?
Of course!
She jumped up, motivated by her sudden epiphany.
She had done this all wrong! Instead of trying to do all by herself she should have searched to find whoever created that pendant in the first place!
Reality sunk in again when she saw the mangeld and brocken door that was now hold together by the thick boards on the other side.
Right, she was not allowed to leave.
With a gaze to her hand where small slivers of green light started to shine, her face took a determent expression.
In the following hours the sound of explosion after explosion echoed through the Dursley residence. Petunia Dursley looked quite a bit scared when she calmed down their neighbours when they came asking what the hell was happening.
"Please excuse the noise, we are doing some construction work." Was her most often used excuse, completely ignoring that no construction worker van or anything in that regard was parking in the entire street.
While her aunt tried to make up a believable story for the noise, Rose tried to catch her breath.
To avoid being hurt by her own explosions she had wrapped herself in her blanket, a bunch of old clothes and had positioned her mattress directly behind her to catch her should she be thrown back again.
This only avoided the worst though.
By now she felt even worse than after a particular intense round of Rose-hunting.
With a disappointed glare she examined the results of her work.
At this point there was no piece of furniture intact left. Unfortunate this wasn't the case with the door though.
While certainly worse looking, what ever uncle Vernon had done to it had made it more durable.
Frustrated she let herself fall down to the floor.
This wasn't working, she had to try something else, less the explosions would break her before that stupid door.
Pulling herself free from her makeshift armour out of blankets and clothes.
"The big problem is that I hit everything not just the door." She mused.
"I must direct the force more."
But how? When she compressed the power in her hand it would just explode in every direction afterwards.
Frustrated she kicked a small piece of rubble against the wall, it collided and was reflected back at her but she kicked against it again, causing it to fly once more against the wall.
She set on to just kick against it once more when she suddenly stopped.
"Could it be that easy?"
She had thought that the problem was similar to her not being able to sense or use her own magic but perhaps she had overcomplicated the problem?
Carefully she gathered a small amount of power in her right hand and compressed it.
It wasn't much, just enough to move the rubble around her and cause the air to slap in her face when released.
But she wasn't finished yet. Instead of letting the control over the mass of collected power fade, she stretched out her arm and pushed with her remaining power against it!
A load bang sound ripped the pieces of broken wood, stone and plaster up from the ground and throw them against the other end of her room. A cloud of dust soon obscuring part of her view.
Yet Rose herself wasn't hit by anything!
No sudden slap from the air against her face, no unseen force slamming into her torso, nothing!
Coughing she tried to wave the dust away.
When the dust finally settled down, the sight caused her to laugh.
In the front of her was a cone-shaped, rubble-free zone.
This was it, she decided. Her first spell and her ticket out of here.
The explosive blast was stronger compared to the explosion from before, and now she wouldn't have to be careful with how much power she used.
Just for fun she repeated her action from before, slamming the remnants of her bed against the wall.
She giggled when she saw it breaking even further, while she was perfectly fine.
This was great! She decided.
In her imagination she pushed Dudley or even uncle Vernon away from her. She imagined how she blasted the door away and left Private Drive just like she had tried before with Cirilla.
Perhaps she now even could do something against the other mages with their sticks! In her fantasy she saw them throwing lightning against her… okay perhaps better not testing that one. She still didn't liked to remember that particular situation
But she could leave now! She was certain of it!
She could go to London and… she hesitated.
To be honest, she hadn't really thought much about that. Sure, she wanted away from the Dursleys and back to Cirilla, but what then?
How would she get to London in the first place?
She believed there to be a train that drove there regularly, but she wasn't certain.
And what would she eat? Where would she sleep?
She was certain that as soon as she found who sold the pendant she could find her mother, but what was until then?
She certainly wouldn't return to the Dursleys. Who knew what they would do next after she escaped? This had escalated quickly recently; she didn't want to know what they would do after she escaped once.
No, as scary as it was, she would have to face the unknown and hope for the best!
At five a clock Vernon Dursley arrived at home.
He was immediately welcomed by his panicking wife.
"She is going to bring the house down, Vernon!" She cried.
"Since I told her that we wouldn't let her out it had been one explosion after the other!"
Mr Dursley made a sound that reminded someone of an angry sealion.
That girl had been nothing but trouble lately.
First, she started to summon spirits or whatever nonsense she had done at school and then she suddenly almost brought down the house!
He didn't know where he had gone wrong with that girl.
Had he left her too much lash recently? Perhaps getting her own room had grown to her head.
Until a few weeks ago everything had been under control.
The girl stayed in the cupboard most of the time and every moment of her freakishness was quickly punished or put down as some nightmare.
He was certain that she mostly didn't even realize what was happening. She at least didn't realize that some of the weird dreams she cried about were creepily similar to the news he would read a few days later.
Still easy to ignore and to put down as mere nightterror.
Of course, there had been moments that had been difficult to ignore.
For example, when Petunias scissors were ripped from her hands by an unseen force and thrown through the room when she had decided to cut the girls freakishly white hair short.
Or that one time where the girl had suddenly spoke with the voice of Petunias dead sister.
A shiver went over Vernon.
That had truly been the worst one. They had kept the girl in the cupboard for days before they could stand to see her again.
But now the girl seemed to have realized her own abnormality and decided to make that life of poor upstanding citizens like them a living hell!
Before Mr Vernon's mental eye, the image of a young whitehaired woman flashed and he bawled his hands into fists.
It was all that woman's fault! First, she made him hope to finally be free from that waste of space, just for the other freaks bringing the girl back and demanding that they made "her felt loved and at home".
He almost laughed as he climbed the stairs and locked at the door to the girl's room.
Hadn't they tried? They had given the girl even her own bedroom!
And what thanks had he gotten?
Disturbed teachers and exploding bedrooms!
He arrived at the girl's door.
Or what would once have been a door.
After that brat had almost ripped the house apart, he had started by enforcing the door not only with thick boards, no after overthinking it he had added a couple of metal bands above it and fixed the to the wall.
At this point it would take a day's work to get this open again.
Briefly he had considered to paint the whole thing over, just to be able to pretend that the girl had never existed in the first place. But the fact that at some point people would ask questions about her whereabouts had stopped him.
In a few years the girl would hopefully come to her senses or -and at this thought a small smile caused his moustache to vibrate devilishly- they would have no problems getting their niece admitted to some kind of mental hospital.
Frankly the thought had come to him a few times in the past already.
With a few heavy knocks he attempted to make himself known to the room's inhabitant.
"Your behaviour is not acceptable girl! If you are so set on bringing the house down, you certainly don't want to eat anymore!"
He waited a few seconds but no answer came.
Honestly, he wasn't sure if the girl could actually still hear him, the door had become pretty thick after his "adjustments". Petunia always communicated through the flap he had built into it, but he refused to go down on his knees for that brat.
"Do you hear me girl?! No food until you start to behave yourself!"
Or until they remembered it at least. Sometimes the "forgot", they were only human after all.
Still lacking an answer Vernon Dursley turned around and was in the process of leaving, when a load bang caused him to flinch.
Angrily he turned around.
"What have I just said gir…" He called to the door, but what he saw there stopped him.
The metal bands had deformed under the sudden movement of the door. The thick boards started to show deep cracks and at the places where the bands had been connected to the wall white dust started to trickle down the floor.
His eyes almost pooped out of his head as he realized what an immense force must have hit the door just right now.
"Girl! I am warning you…!"
But Vernon Dursley should never finish that sentence as in the next second the heavy door, and a good chunk of the surrounding wall, flew straight into him, knocking him of his feet and slamming him straight into the neighbouring door.
He never saw Rose exiting out the newly formed opening, Dudley's old backpack on her back, sprinting down the stairs, pushing aside a terrified Petunia and jumping on the street before Privet Drive number 4.
