On the one hand, yay, a raise! On the other hand... I don't know what sleep is anymore...
There are two distinct sides to this girl - her work mode, and everything else.
At work she shows initiative, curiosity, boldness and creativity, wanting to be a step ahead of the curve. She's motivated both by the need of funds to finance her brother's education/life as well as her strong sense of justice, looking to give people the truth from the most unbiased point of view she can muster. Most of her articles nowadays are small time, unfortunately, due to her being a rookie in the press and having yet to win the full respect of her peers (and editor/boss). Despite this, nobody can deny her work ethic.
Outside of work, she takes a complete 180º turn, almost like she turned off a switch. In truth she's very quiet and demure, opting to keep to herself whenever able - she prefers to stay at home with her half-Kneazle, Brownie, and prefers solo activities more than anything else. Very much an introvert, her geeky habits fed into her imagination, which in turn made her the excellent writer she is today.
She is kind to those she meets, even if she's not particularly fond of them or antagonizes them - she doesn't think conflict helps and tends to avoid it like the plague, trying to be understanding instead. She never raises her voice either, and nobody really remembers ever seeing Diana openly angry about anything.
She has a (very much appreciated) tendency of flying under the radar - people rarely notice she's there unless she happens to speak up, she doesn't have a very solid presence, and is very much a background person in most situations (save for when people close to her are involved). This helps in investigative journalism and observation as she's often left to her own devices without much suspicion.
She's extremely consistent in her work ethic and respective quality although she doesn't believe she's that good at anything. In fact, she has several self esteem issues stemming from having her legs proverbially cut off at various points in her life, such as when she was ripped away from Tallygarunga and when the person she's interested in went for Diana's best friend instead.
Despite having a very clear moral vision and sense of justice, she's not above stepping on that notion to get a much needed something accomplished - the best example of which is her deciding to alter various minds for the benefit of her brother's freedom, despite being very much against doing so and having to live with that for the rest of her days. Ultimately the ends justify the means and she acted in the interest of the greater good, or so she tells herself. She's just able to do anything for those she calls 'her own' at any cost, even if that cost is losing herself.
Her upbringing has made her a pessimist, although she does her best to put on a strong face and brighten other people's days if she can. She doesn't want to perpetuate the abuse her parents took out on her and wants others to feel the exact opposite of what she felt back then.
Diana is quite slender and petite, her frame not being built to take sports too seriously, but fortunately has quite the hard time putting on any weight to begin with. She stands at 164 cm and is quite happy about her height. She is often confused to be younger than she actually is (a Tallygarunga student still, for example) much to her chagrin.
She's of the firm belief that if it weren't for her wavy blonde hair and pale blue eyes, she would've gone so much under the radar people wouldn't even know her name. When she is indeed noticed, she's mostly seen with a pleasant smile on her lips.
She likes experimenting with her wardrobe, having it range from casual chic to rebellious to quite girly and changing in between those styles at the drop of a hat. It's also not uncommon for her to tie up her hair in a ponytail. As for work, she has to wear reading glasses at times.
Despite her general shyness and quietness, Diana's network of acquaintances is quite large (most of which deliberate as well, so to have sources). As far as actual friends go, however, one could count them on one hand; and those who breach the status of friend automatically become her close friend with no in between, given how she has a tendency to invest in friendships greatly and becoming a sort of confidante for all of them.
She usually places her friends' needs above her alone, to a self sacrificial degree. She's lost count of how many times she's gone out of her way to appease to them and continues doing so to this day, having a fierce loyalty to them and being unafraid of breaking a few rules in their stead.
Unfortunately, Diana only has one person remaining for a family - technically, anyway. Having erased her own and Gideon's existence from the small town of Mildura, her parents are none the wiser to the fact they've actually conceived two children. Ever since that fateful day it's been Diana and Gideon on their own, and it still is.
She's very overprotective of her brother, capable of doing egregious things (as seen above) to achieve what she believes is best for him. Her actions eat her up inside every day but the fruits of her labor are showing and she couldn't be more proud of her little brother and his education through Tallygarunga. She motivates him to pursue his dreams and make friends as much as she can, and visits him often at school.
Back in the day, during Tallygarunga and the start of her VMU career, she used to idly date - it became a bit of a reputation that most people wouldn't notice her, but those who did would become fixated on her for extended periods of time. Diana's always felt self-conscious over that fact, feeling that she's unwittingly ensnared people and possibly destroyed their love lives for a large period of their lives, and as such she's grown to relish the fact she tends to go by mostly unnoticed even more.
At a point though, tables were reversed as she hopelessly fell for someone, and remained in such a way for several years, up to this day - though, unfortunately, that person is her best friend's partner. As such she's vowed to stay out of the way and hasn't spoken of it to a single soul, but she's not dated anyone ever since either, claiming she's 'lost interest'. It remains to be seen if she can move on by herself at all, let alone be able to like someone else.
Diana's never had a whole lot of these outside of work - being a mostly likable individual, it was fairly hard to make enemies (if people noticed her at all); as for bullies, she was blessed with having fairly strong friends growing up and as such if anyone dared approaching her she would have been protected, and they would've given up after a while.
As for within work, she does work in a bit of a competitive industry - it could be that someone perceives they were stepped over by her in the career ladder, or someone who has her in their sights; there could even be a story or three where she's chased down a number of people and some didn't take too kindly to her questioning. She apologizes for upsetting people, but then again she's just doing her job.
Diana is the first born child of an accountant, Dwight Sharpe, and his wife whom was a local nurse, Carina. They were very young when they first had her and the family went through a number of financial troubles because of it, but Diana herself was never bothered by this too much - she was always able to entertain herself as a child with the most mundane of things and was rather quiet and modest, never really asking for anything. She never gave much trouble to them and they were appreciative of the fact.
Of course, this took a bit of a turn when the seemingly normal girl started to display strange powers as she grew up. Her parents were horrified of this and only wanted their daughter to be normal, but the idea of having her sent out to dormitories to receive a mostly free education weighed in heavily on the couple due to their financial difficulties. They ultimately opted to send her to Tallygarunga. Ironically they had their second child at roughly the same time, so this did little to actually improve their monetary problems.
Diana was enchanted by the wizarding world, no pun intended, on first sight. She knew that was the world she wanted to live in, what she wanted to explore and immerse herself in, what she wanted to die by. However, fate conspired against her - her parents both received promotions and bonuses, and steadily they saved up enough to rip Diana away from the 'blasphemous' education she was receiving just as she ended her fifth year in Tallygarunga. She was torn away from her life and her best friend and placed in a Muggle high school instead, much to her dismay. She was also forbidden to refer to magic in any way, practice it, or keep in touch with her fellow peers (which she did, regardless, since they couldn't do much about it to begin with).
Always having had an eye for prediction, she took it in stride and did her best in the Muggle school (a lot of knowledge which she was lacking, and had to 'cheat' her way through various tests, given that Tally never taught such needless things). While she was passing through the years she made an effort to fit in by writing for the school newspaper, and eventually for the local paper so to save some money to eventually leave. She didn't need that much at all, fortunately, since the stay in Tallygarunga was free and that was her first objective.
As she came of age, her brother started to display magical abilities of his own. She knew that their parents would not allow him to nurture that talent so it was finally time to take action. Instead of enrolling in college, like her parents wanted, she tampered with their memories to erase their children from existence. Added to that she also tampered her way into having her brother under her legal guardianship. With those issues out of the way, she took him all the way to Narragyambie overnight and enrolled him in Whitlam Bilby, while she herself returned to Tallygarunga to finish her education.
Her best friend had let her stay in his place after she graduated, so she could get her bearings - having a little money leftover, she managed to pay her own way through VMU while letting her brother live in Tallygarunga for the time being. It was in VMU that she met the one she believes to be the love of her life. For once, away from her parents, it felt like her life was finally starting to make sense.
Unfortunately the object of her affections began a relationship with Diana's own best friend instead. It seemed that life was throwing another curve ball at her - but at least she didn't actually hold any ill will towards them, unlike she did with her parents. Leaving them to do their own thing, Diana managed to move out and secure a small apartment in Melbourne for herself (and for her brother, of course, whom now finally had a residence that wasn't a dormitory if he so wished). She fully plans to throw herself at her job and ensure her sibling doesn't have to face half the problems she had to face on her own, and money solves a whole lot of troubles, now doesn't it?
With her pulling away from Kyle and Amalea, Diana was finally able to fully focus on work and Gideon, her little brother. Not too long before the move, an old friend of hers returned to town and stationed herself in Tallygarunga - it was an extra set of eyes to keep the young Sharpe out of trouble, something Diana very much appreciated.
Down the first trimester of 2019 another blast from the past showed up, though that time it had been in her friend's life - and Diana was entrusted to pull strings and figure out what had happened for this person to disappear in the first place. She wound up uncovering a harsh reality of the Dhampir community in Perth, WA and grew wary of anything associating with May Bowen, whom had once been someone she liked to consider a good friend but has been on thin ice ever since.
Her paranoia over the danger the woman could bring to Victoria increased as Gideon told her that his roommate, Ian, was receiving blood bottles from his sister, said May Bowen - except, the 'Ian' sibling she'd had had an obituary listed from several years back, and the cause of death had been suicide, meaning he was under some sort of protection program. She had a very bad feeling about it all, and for once, felt like she had to rail against her own friends to keep her kin safe.
