Hermione Granger has always prided herself on being able to get out of any situation with her quick wits and vast knowledge. Again, her knowledge pertains mostly to the Wizarding World, as she spent the last seven years of her life going to Hogwarts, a magic school.
When Hermione was eight, her parents were killed, and Mr. and Mrs. Queen (yes, Queen) wrote that unless he was incapable of caring for her, Hermione's twenty year old brother, Oliver, would be her guardian. At the time, the elder (surviving) Queen was a party boy, allowing others to care for his parents' company, Queen Industries, and for his baby sister. When Hermione was ten, her brother disappeared after he was shipwrecked. During his disappearance, Hermione received her Hogwarts letter and Professor McGonagall's visit, convincing her that she was a witch.
Two months before she was ready to depart for Hogwarts, Oliver resurfaced. Hermione wasn't allowed to read the newspapers dealing with Oliver, nor was she allowed to watch the news during the period. After Oliver's return, his neglect augmented as he became more focused on Tess "Mercy" Mercer and rebuilding his image with Queen Industries, thus, when Hermione told Oliver (or rather her butler informed Oliver in passing) that she was going to a prestigious, unknown boarding school, Oliver readily agreed, glad to get rid of Hermione as a burden.
Hermione changed her name to "Granger" for anonymity (after all, it didn't change her blood status, not that she would want to) and only returned for summer holidays. Oliver never questioned why his sister was getting more serious and worried, nor de he question her various injuries that were results from her escapades as a part of the Golden Trio (comprised of her and her best friends-Harry Potter and Ron Weasley).
The summer after fourth year, after Cedric died, after Voldemort rose again, Hermione took a short visit to her brother. Telling him that the strain of traveling constantly (though it wasn't constant at all) was too much and she'd stay in touch (she knew she wouldn't-she had to keep him safe) and that she'd miss him as he'd miss her (a complete lie, as they were practically strangers to each other), Hermione packed the most important things she would need for the coming years during the war, knowing she may never return.
In the coming years, Hermione faced countless death eaters with her friends, demented teachers, unimaginable deaths, torture, horrid violence, accumulated scars, and never contacted her brother once. She couldn't help but be hurt that he never tried to contact her.
While Hermione was on the run with the rest of the Golden Trio while searching for Horcruxes, Hermione faced starvation, cold, and was tortured twice-once at Malfoy Manor and once at the Final Battle of Hogwarts.
Each scar meant something to her.
There was the one jagged healed scratch from when she pushed herself against a broken piece of wood to avoid being shmushed by a troll on her leg.
There was the mental scar of her heart beat rising eveytime she blindly took a corner, scared she face another basilisk.
There was the scar of mistrust for government bred by years of corrupt Ministry dealings, ranging from Sirius' false imprisonment, Buckbeaks joke of a trial, Fudge's trust in Umbridge, Scrimgeour trying to take advantage of Harry, the list goes on and on.
There were the scars wrapped around her stomach from when she was hurt in the Department of Mysteries.
There were the scar where Victor grabbed her so hard, he broke her wrist while drawing her out of the second task.
There was the scar on the back of her neck from the night Dumbledore died.
There was the scar on the back of her hand "I must not tell lies" from Umbridge's reign.
There was "mudblood" carved into her arm from Malfoy Manor.
There was burn marks on her torso from being tortured at the final battle.
There were too many scars to count.
The question was, between her physical and mental scars, would she and her brother be able to reunite after all these years and act like siblings, as they hadn't attempted to actually play a role in each other's lives since before Hermione's parent's deaths.
