Lavali Chatterjee and Jacoby Malone - one of the most dedicated members of the Order of the Pheonix, and one of the least pleasant initiates of the Death Eaters respectively - are a unique presence in the works of history due to their intertwined past. While it could not be said now, seeing from their entirely different paths, the pair were once close friends.
They met eachother through their mutual house, Hufflepuff. It was their past that formed their bond... poverty... even if it belonged to completely different walks of life. (Jacoby grew up in Ireland, while Lavali moved to Britain as a young girl from India.) However, time went on, and the pair reacted quite differently to their past.
Lavali saw it as an opportunity to realize the misfortunes of others, and strived to always better those in situations worse than her. Jacoby, on the other hand, turned to violence against those better than him as revenge, and was constantly hopping from brawl to brawl against the wealthy of Hogwarts.
Time ticked on, and the pair went their separate ways... Lavali working to be the best that she could be, and Jacoby losing both soul and body (his eye was taken in a duel) to he-who-must-not-be-named and his own wrath. Yet still, it is rumored that when the two crossed paths, there could always be a glimpse of doubt seen in their eyes... A shadow of choices made.
Danny closed the textbook with a shudder, adjusting his cap, and glancing at the moving Quiddich poster hanging on the wall, trying to imagine the darkness that must possess a soul to join the Death Eaters. He could never do that... never kill and personally try to cause misfortune.
Not that he didn't understand where Jacoby came from... the bandages on his own face were plenty of proof for that...
However, there's always someone far worse off. There was always someone else who needed to give that punch more. Always somebody else out there who needed a hand. Serving oneself wouldn't get them anywhere, now would it?
He put the textbook on the shelf next to his bed, and then let out a sigh. One day he'd like to do something good with his life. Something like the people in the historybooks.
Perhaps the Order of the Pheonix would be a good place to begin.
