A little step back from the characters of the series. I was thinking of having one of Galahad's crew tip Newt off about the Circus critters, but it seems there was no time for that to happen at any point in the movie. Please correct me if the timeline is too far off.

Chapter contains mention of sexual assault.

Blood Brothers

"Gal, if I undo your bonds now, you will go over to warn Miss Queenie's sister, right?" Bedivere asked. Galahad was trembling under his bonds. The healer took his silence for assent and freed him. Somehow, he sensed he would come to regret it…

Galahad bucked up so suddenly, he unseated Bedivere. Next came the punch to the side of his head that made him see stars. Before he could regain his bearings, a fist smashed into his solar plexus, leaving him gasping in agony on the floorboards.

"I beg your pardon. We will talk about my issues later, much later…" Galahad ruffled Bedivere's hair. "I think I have an appointment to keep with yours truly…"

"Merde! Don't tell me you are falling for that too."

"More than one of us have received this… Stay put now…" Galahad took out a rumpled leaflet from his coat. He pointed his cane at the hand mirror.

"Percy's dead because of him… Gal!" The blond had vanished from the attic.

Bedivere picked himself up. He should have guessed there would be trouble. Arthur 'Squibby' Graves who ran the Black Creek General Store had alerted them to an odd batch of Woolworths catalogues he received before Halloween. They were distributed to stores and homes all over the country. He tossed them in the store's safe until Galahad found time after Thanksgiving to look at them. When handled by a wizard, the catalogues transformed into a manifesto of the Alliance. The flyers had made their way to numerous Magical homes over the past months before MACUSA managed to catch on and contain the damage.

Queenie had been easy prey. Now she allowed Vinda to take her to one of the bedrooms, tastefully refurnished by Vinda to appeal to Queenie's sensibilities. Grindelwald watched the women leave before he turned his attention to the mirror. He frowned. Yes, it was not his imagination. The mirror above the mantel throbbed with power that had not been there earlier.

"Come on out," he muttered. He had his acolytes spread the word far and wide in the past months. Someone was foolhardy enough to taunt him by placing a reconnaissance spell within his recently acquired abode. The audacity of this intruder…

"Greetings, Gellert…" A flurry of his own leaflets scattered in a whirlwind before settling. "Or should I call you Big Brother?"

The newcomer was standing beside the rocking horse, the plaything of the child who once lived there. He was dressed in a tiger-stripe suit of smoky grey. His hair was pale blond and the eyes that stared fearlessly back into Grindelwald's were cornflower blue. The scorpion collar pins were familiar. No doubt MACUSA had returned them to Graves' next of kin once the trial was over.

"My parents would have told me if I were not an only child," Gellert considered the newcomer. This one oozed magic, dark magic too. A possible asset…

"Half-brother if you wish to be exact. Your father seduced my mother and abandoned her. So there. If he were about, perhaps we can ask the old man how many other half-siblings we have out there… but I forget my manners… My name is Galahad Graves…" he offered his hand to be shaken.

"Graves, a familiar name – was Percival Graves a relation of yours? Are you here to seek vengeance?" Galahad could sense the probing of legilimency as Grindelwald shook his hand. He put all his occlumency into play in reply. He was about as good as Rosier, Grindelwald noted.

"Percy always was an honourable fool. He will be missed, just a little. My mother's Elaine de Lance. A cousin on your mother's side… So we are kin twice over. Now shall we get down to business? I doubt you are the sentimental type."

"So you wish to join our cause?"

"No, I would like you to leave things as they are, at least in the States. Overthrowing the Statutes of Secrecy will be very bad for my family's business interests…"

"How American," Grindelwald sneered. Galahad was showy where Percival was more restrained. The manticore-tipped cane, ridiculous boater. He could have been a hustler at a circus. "If I refuse?"

"I suppose there might be other opportunities…" Galahad smirked. "If one knows where to look… or we can end this now…"

Grindelwald saw the flash of a blade as his visitor lunged at him. He hurriedly dodged the thrust and cast a Stupefy, which Galahad blocked.

"Imperio!" Grindelwald shouted. Galahad's attack faltered. He dropped to his knees and grappled with the dagger, panting. He was now fighting against his own body. His hand twisted around, bringing the point of his dagger close to his throat. Then just as suddenly, the spell snapped. Grindelwald dodged the dagger that was flung at him, but not fast enough. The point sliced through his sleeve and grazed his bicep before lodging in the wall behind him.

"Accio," Galahad picked himself up caught the bloodied dagger that flew back to him. He retrieved his boater and cane in the same way. Dusting himself off, he straightened his lapels. It was all an act, an audacious but calculated act. If he had cast a Killing Curse, would Galahad had blocked it with nearby furniture?

Footsteps announced the arrival of Carrow and Nagel, who burst in with their wands drawn. He waved at them to stand down. Thankfully, Queenie had not come to investigate the commotion.

"Shall we continue this discussion in a more civilized manner, like over drinks?" Their eyes met. Mismatched eyes into blue. Grindelwald made use of that moment to shove past Galahad's shields.

A children's nursery, no, a mock-up of one. Rough hands touching him where they were not wanted… Strange men wanting to play their sick games with him and the other children… His sister… where was his sister?

"Sir?" Carrow asked as Grindelwald staggered back from shock and the other wizard's shields snapping back into place. Galahad's face remained impassive. A trickle of blood oozed from his nose. That memory was one he had studied too many times. He always kept it close to the surface, ready to be used if his shields were breached.

"You do not look too well, Gellert. Perhaps another time." With a twirl of his cane, Galahad was gone.

"Sir?" Carrow pressed.

"Let him go and leave me… NOW!" His acolytes gave a curt nod at their dismissal and walked out, shutting the door behind them. Grindelwald did not want to appear weak before them. He cast a quick healing spell on his arm. It was a mere scratch.

"Bombardo," he pointed the Elder Wand at the mirror and blasted it to smithereens. It was a pointless act of destruction. Monsieur Graves had already lifted the spell on it. Grindelwald knew he would have nightmares that night. His own brother and perhaps a sister…

More evidence some Muggles were not to be trusted to even live. Would things have been different if his father had acknowledged and provided for the bastards he had sired? Would Mutti's pureblood pride have allowed it?

"Gal!" Bedivere caught him as soon as Apparated. His knees were shaky. He was trembling like a leaf in a gale. The healer looked him over. "Side-along. No arguments!" Bedivere retrieved their possessions from the attic, took Galahad's arm and tucked him close before they Disapparated out.

He chose the crypt under Notre Dame as his destination and sent word to Pellinore and Kay. He did not want to impose on Nimue's honeymoon or work. He had never seen Galahad in so bad a state for many years. The last round, Timmy had been there to ground him. Kay was the first to respond.

"What did he do this round. Try to raise the dead?" The last time that had happened was when his mentor decided he needed to be taught a firm lesson on not messing with the dead.

"If only, he went to face Grindelwald and I think he got a hole punched hard in his shields."

"Wish Percy were here…" Pellinore added. "Gal would pull himself together just for the sake of punching Percy in the face…" he held out Bedivere's doctor's bag.

"I am out of Dreamless Sleep…" Bedivere snapped as he rummaged through it.

"N-no…" Galahad's hand clutched at his coat like a drowning man. "Don't want to forget… her…"

"Shh, it is just to calm you. Come back, Galahad… You are safe… Your sister is safe… Nothing can touch her…" Bedivere rubbed soothing circles into Galahad's back while his free hand scribbled a list of ingredients to be purchased by Kay or Pellinore. He continued rubbing circles and repeating his reassuring words until the blond wizard's racing heartbeat slowed, and his breathing became more regular.

Kay transfigured one of the sarcophagi into a bed and they laid Galahad on it. The healer did a quick check for further injuries they might have missed.

"What's this?" Pellinore noticed the bloodied dagger unsheathed inside Galahad's coat.

"He drew blood. Save that now. Gal might need it later…" Bedivere instructed as he tucked his patient in. There was silence. The wizards knew blood could be used for a variety of purposes in dark magic.

"Coo-ee, Percy would toss all our asses into a jail cell for this one," Kay remarked.

"Aren't we so lucky Percival is no longer around for that?" Bedivere smiled ironically.

"Mutti?"

He should be in bed like a good little boy, but he had a nightmare. The light in Vater's study was on. Rubbing his eyes and confused with sleep, he went there instead. His formidable father was there, pants down to his knees and bending over the desk. Pinned between the desk and Vater…

"Anya?" The boy recognized the tear-streaked face of the junior nursemaid. Unlike other wizarding families, Vater never cared for house-elves. Instead, he hired local Muggles, half-breeds, or squibs as servants. Her face was bruised. Her dress was torn. He could see blood running down her white stockings.

"Leave now, brat!" Vater snarled at him. "Breathe a word of this to anyone and you will be sorry!"

He had been too young to fully comprehend what was going on, or why Anya went away a few months later. The maids at their mansion were constantly changing. The young pretty ones never stay long. There were always more young girls offered by their parents to take their place. When Mutti's health started failing, Vater became more brazen in his ways. He would leave his wife at home while he seduced young witches in society, witches whose families dare not or could speak out against him for fear of ruining their daughters' reputations.

When Mutti's illness progressed to the point where she was bedridden, Vater brought his women home. Some were entranced away from their families. Others were women of dubious repute. It made Mutti cry to hear Vater and his paramours disporting themselves across the hall. He was too old for nursemaids by then and Vater had to qualms about letting his son witness him carrying on with his women or the maidservants.

At ten, he had confronted Vater about those women and had been struck for it. Vater then went off on a drunken rant about Mutti's failure to meet his needs and how he was justified to meet those needs elsewhere. If the women were too weak to stop him from ravishing them in the first place, it was their fault. In his world, only the strongest had the right to live as they wish.

"So weak, like your worthless mother," Vater had taunted him. "A pretty, little freak. Perhaps Durmstrang would make a proper man out of you." Vater always hated his mismatched eyes and how he had inherited his mother's looks instead of his. Gellert had received his one of his first visions then – his father lying dead at the foot of the staircase and a young witch fleeing into the night. He never blamed the witch. Any one of those young women could have borne his father a child. Or perhaps even one of the family's maids.

The marriage between his parents were arranged by their families for the sole purpose of maintaining the purity of their bloodlines. His parents often fought, shouting at each other and sometimes wands were drawn. Sometimes, Vater just ignored Mutti, especially after she became ill. If there was any love between them, it died when Mutti was unable to bear his father another heir. They had already waited a long while to have him. They tried, but the babies never lived, so Mutti told him.

Elaine de Lance.

He had checked up on his family on both sides after he was expelled. He had found Grandaunt Bathilda, a British cousin of his grandmother on Vater's side. Mutti's family had little connections he could use. The de Lances or Delances had migrated into the New World or died out over the last century. They were related on his mother's side. Mutti refused to have anything to do with her family as far back as he could recall. She had denounced them as a pack of ingrates. He always sensed there was something stronger behind the dislike.

There was a name on the family's register that had been struck out. He had tracked down their old housekeeper, a part-elf on the verge of senility. She had recalled a Fraulein Elaine, an orphaned cousin taken in by his parents as a child.

"They loved her. Could not bear to even send her away to school. Master Gerwyn tutored her himself. Lovely little thing she was, part-veela so they say… but she went away after Master Gellert was born…"

It was not unheard of for a magical child to be home-schooled. Or for a pureblood family to take in a distant pureblood relative to protect the bloodline. Perhaps his worthless father had indeed conducted a liaison with this cousin and gotten her with child.

Author's Notes:

I cannot find much background on Grindelwald's family. I choose to have him pureblood but with utterly dysfunctional family life. Gellert is not a pureblood supremacist as he has witnessed the hypocrisy behind the entire blood status thing. He respects and values magical power over blood purity.

Vater (German) – Father

Mutti (German) – Mommy

The duel between brothers ended in a draw. As mentioned earlier, a theory is that Grindelwald has lost the Elder Wand's allegiance and has not regained it. So no risk of wand loss to his brother.
