Bloom's seven now, and her trick with holding fire never went away or was forgotten.
She quickly discovered that only she can touch fire and be unharmed - and she alone knows she can shape it into any form she wants. At first, she was going to tell them - then, she thought of what Thor would say or do if she told him she could shape the fire from a torch into whatever she wanted. That thought, the thought of more belittlement and scorn from him, is enough to make her keep this little ability to herself - at least for now, she's never planned on keeping it a secret indefinitely.
She's walking out of the training room now, fed up with Thor's disregard for all the work she's put into trying to learn to use a weapon. Ever since she picked up her first sword, Thor was convinced she had no hope of ever being any good at it.
She can still remember that day, she tried to pick up the sword in front of her with one hand like she sees everyone else do all the time, the tip of the sword never left the ground. When she grasped it with both hands, the end of the sword went up into the air - then started wavering as she tried to hold it still, earning mockery and scornful laughter from Thor.
Now, she can hold the sword perfectly still - as opposed to when she was attempting to lift a weapon that was as tall as she was; but he still thinks she is worthless with a sword, that's when Sif stepped in and started teaching her herself. That particular description hurts worse than most he makes, so she didn't tell everything she can do in earshot of him - he'll likely say it's got no worth either.
Loki always says Thor belittles anything he can't do, but Bloom thinks a king should have much more of an open mind - would there have been a peace treaty with the Jotuns if Allfather had Thor's mindset at the time? Bloom seriously doubts it, she's heard him say the Frost Giants should fear him as they fear Allfather.
Bloom can hear footsteps coming down the hallway as she turns out of it, too heavy to be Loki or Frigga's - who were also watching her training along with Allfather and Thor - and it's too hurried to be Allfather; so it's got to be Thor.
Mother and Father likely made him come and apologize, too bad this isn't just once or twice. I really don't want to talk to him though.
She gets a grin on her face, and remembers her brothers' infamous trick - 'get help!' Loki would pretend to be hurt while Thor dragged him, then Thor would throw him into whoever they wanted to get away from. Demeaning and embarrassing to Loki, and it got them into massive amounts of trouble every time they used it - as they were making it out to be Loki was dying.
Bloom can't exactly do that, or any variation of it, for a number of reasons though: all stemming from the fact that she has no partner to do it with.
Making a big commotion just gets you caught in the end, something quiet however…
She has already mastered illusions from Loki by now, so what she's thinking is no stretch of the mind: an illusion covering her, one of empty air. She's not entirely sure how she does it, she just imagines something and it appears - so if she imagines she's not there…
Thor pounds around the corner, looking around for his little sister - his eyes pass right over her, despite the fact that she's in the middle of the wall. "That girl and her magic, where could she have gone off to already?"
Bloom can't fail to stifle her laughter, and quickly makes it so that her illusion blocks the sound from getting to Thor's ears.
This is perfect. I can become invisible with none the wiser.
All she has to do is be careful of where she does this and where she drops the illusion. She makes her way to the library, where she immediately drops the cover once she's safely hidden away in the bookshelves with her books that have never once made her feel small or not worth the effort - because that's what Thor said this time, she wasn't worth the time and effort of trying to train her. She stormed out of the training ring, justifiably so, and everyone is probably looking for her.
She's on about the dozenth story when Loki comes in the room looking for her - unsurprisingly, he finds her. "Bloom, where have you been? Mother, Father, and I have been looking everywhere for you."
Bloom sighs and says "I came here, Brother, when I left the Training Ring."
"If it's any consolation for Thor's words, Mother and Father were furious with him, and disappointed."
Bloom says "Well, wonder how many times they'll be disappointed when he takes the throne."
Loki shakes his head, and says "You know it's still a possibility they won't choose him."
"He's the Firstborn, Loki. Besides, I don't want to be Ruler of the Nine Realms anyway, it sounds really boring and like a lot of work - Father is always on the throne most days." She has a point, and she's always been too hyperactive to stay still for more than a few minutes when she's not reading or concentrating on magic.
Loki sits down next to her, and asks "You feel like you're in Thor's shadow, the shadow of his glory and greatness that everyone else it too blinded by, don't you?"
Bloom looks at Loki, and seems to see something in his expression - hyperactive or not, Bloom's always been extremely smart, along with compassionate and almost empathic at times. "I'll be your light, Loki. I'll be your glory. I'll master magic like you, and then you'll be able to say 'I taught her everything she knows.'"
Loki smiles despite himself, and pulls Bloom into a hug - she really knows how to say exactly what he needs to hear sometimes, this was definitely one of those times. He's felt like he's just living in Thor's shadow for years, getting no glory or recognition for his own talents - somehow Bloom manages to say the stuff that means the most to him without even realizing it.
Somewhere between now and when she first turned invisible, she decided to keep this particular trick of hers a secret - Loki already taught her to keep a trick or two up her sleeve, this can be her trick - nobody, literally, will see it coming.
When she pulls out of her hug, she's got a gleam in her eye that can only mean she's learned something new in magic. He smiles at her, and says "Bloom, while you may be good at keeping your emotions off your face for Thor, you can't hide that look in your eye from me. You've figured out something new, haven't you?"
Bloom's lips form a huge grin, and she says "We'll need a torch, Brother." They go to her room instead, where they can do this uninterrupted by anyone - Thor, in particular.
Loki's long since stopped worrying when Bloom grabs handfuls of fire by now, he's seen her do it more times than he can remember now - the shock wears off after a while - and so he doesn't freak when she pulls out as much of the flames as she can hold. He does go still in shock when she starts shaping the fire like a forge master shapes a blade however, she never ceases to have some new shocking revelation when he thinks she's shown him everything.
She molds it into a knife the length of her upper arm, then swings it around in an imitation of Sif's sword swings. It acts like it's perfectly balanced for her, but Loki can guess anyone else will only feel a burned hand - it even acts like a sword would when in her hand, not dissipating when it hits the ground by accident. Of course, it immediately falls to a bunch of dying embers on the floor when she accidentally nearly hits Loki because he got too close. "Bloom, that's…incredible! Do you have any idea of what this means?"
Bloom innocently shakes her head, then turns and grabs another handful of fire to shape. He can see her eyes flashing orange, but shrugs it off as the firelight - which she shapes into a circlet that's the size of Loki's head. "I know Thor's going to get the throne of Asgard, Brother. The crown, any woman he wants for a queen…"
She trails off, and Loki asks "So what's this? Because it won't fit your head." "It's yours. Your crown - because I think you'd make a better king than Thor right now. You listen to me, you talk to me while Thor talks down to me. You care about me while Thor only cares about getting onto the Throne and getting into another fight."
Loki smiles, and says "You'd make an excellent queen. Like father says, you were born to be one."
Bloom shakes her head, and says "But I don't want to be one, Brother. If the throne turns people arrogant and uncaring like Thor, then I don't want anything to do with that boring old chair. I'd rather be in the library, practicing magic with you." She holds up the circlet she's finished making, saying "So, this is yours. Do you like it?"
Loki smiles and says "It's lovely, Sister." When he puts a finger near it, he can feel the intense heat radiating off it. "Bloom, I think you'd better wear it for me though. Remember the sword?"
Bloom nods, and sadly begins shortening it to fit her head instead - making it turn from bright orange like her hair to nearly white with fire and heat. When she places it on her head, it stays there perfectly - but she hates the very idea of it. Sighing, she tosses it back into the fire where it promptly dissolves back into flames when it stops having physical contact with her.
AN: Seriously people, any suggestions would be great! If someone wants to see something, just message me! Yes, it just worked out that way that they're going in order at the moment, but it really doesn't have a particular order. Enjoy, can't wait until May and the next Avengers movie!
