He just stared, not liking what he was seeing. Knowing that he was unable to do a damn thing. His magic was still faulty. He just had to take after his father in magic. And he was not as bright or smart as his sister was. Nor as creative. That didn't mean he was weaker, no. He spent a lot of time with his Uncles Freed and Natsu. Both were interesting, to say the least as both people and as a same-sex couple. They had a shared wife in Lisanna, who he was pretty okay with. Just at the moment, he wanted to beat the ever living fuck outta the idiot who was pawing his sister.

She looked uncomfortable, even as she smiled that smile that was the same as their mothers. Ever since she turned twelve and her body began to change to look like their mothers, he noticed that boys were always staring at her. Talking and saying things that had him wanting to lock them in a barrier with strict rules and induce them with the rune of Pain over and over again. Hell, he had talked to their father about this. And all he was told that his sister was a strong, opinionated girl like her mother. She would speak up when she was ready. Making him think his dad was a pansy.

Growling as he shoved his hands into his slack pockets, Castor watched as that idiot nobles son's hand slide lower to his sisters hip and back to her butt. He was now seven, it was his birthday. And his party was being ruined. Soon his sister would be turning thirteen. Why did all these arrogant, know it all, rich people think that they could act like this and treat any female this way? Why did the rich women marry to them let them? It confused Castor. Of course, as a tiny, plain brunette walked up to him, Caster turned his dark gaze to her and sent her packing. Girls were not icky, just very annoying. His mother and sister aside.

He could admit he barely tolerated his aunties at the Fairy Tail Guild most time. Still loving to pinch his cheeks and coo at how cute he was. But at least the guys in the guild treated his sister with a load of respect. Then again, she could deliver a kick that put most of them on the other side of the room. And after sucking up to Uncle Bickslow, he got the story about his mother's famous kicks. Which he got to witness when she heard his uncle talking about it and then describing how she wore so little clothes that horrified him. His mother was a respectable and refined lady. But the fact his mama got that flustered and his Uncle had gone through the guild's wall and into the pool a good distance away had him fearing his mother more.

"Hey, Caster-oil!"

Rolling his eyes, he looked away from his sister to the group of boys who were four years and older than him. Lifting an eyebrow, he just stared blank faced at him. The way they sneered and jeered at him did little to affect him. And when they said nothing else, he turned his attention back to his sister. To find that she was looking rather flushed in the face as the boy had openly splayed his hand on her backside. From what he could see of her face, her eyes flashing in a manner he had seen only once he smiled and chuckled.

"Looks like he has finally lost it!"

"Yeah, lookit the little Zeigler, such a whipped pansy for his sister."

"Hey, maybe he wants up her skirts too."

That last one had him laughing as he shook his head. He kept his eyes forward as he contained his mirth.

"I have not lost it. Your friend just crossed a line and now he will pay," He said. "My sister is not a possession that you can own and do with as you like. She is not a bird-brained simpleton like these other ditzes of the High Society. She is a vivacious woman who has her mother's temper."

As if time with his words he watched as his sister pulled away, her voice rising in anger. Just for him to step aside from an put a bit of distance between him and the other boys, who were now watching his sister. Then their friend came flying and smashing into the wall. Making him laugh as the boy groaned and slide to the floor.

"Yeah, I wanna see you all try doing something like thinking you can paw at her. Treat her like an object. Because she is working on that kick!" he said as he turned from the boys who were pale-faced and horrified.

He walked to his still angry sister, bowed and offered her his hand. The look of shock on her face before she smiled and took it. Then they were dancing. He looked up at her, hating that she was so much taller than him, even with the six-year gap.

"I think you might have made them back off for the moment, AL," he said. "And thanks for some entertainment at this party. It is so boring having to do this. Droll, I tell you."

At his nickname for her first two initials, Castor saw his sister calm down. And then laugh at his choice of words as they swung around the mostly now empty dance floor. He delighted in hearing his elder sister's laughter. It was truly a beautiful thing. A thing he would protect even if they rarely got along.

"Told you that you didn't need to worry."

"I see, but this is not a good thing."

"And are you telling me that you want to change our daughter?"

"No. GODS, no, Lucy!"

"Good. Because I wont have her being some possession to a little fucking Chretien that is undeserving of our daughter. Though I am worried about that temper of hers and where she got it."

"I have an idea, my dearest."

Brown eyes lifted up to look into amethyst in silent question. Only to get a small, teasing smile and a quick head shake to indicate that nothing more would be said. Just for Lucy to puff her cheeks and pout at her husband. Turning her gaze away from him, she watched as her children danced a perfect dance to the Viennese waltz. She was proud of her children and how they were growing. And knew perfectly well that these young men that showed interest in her budding daughter were mostly because of her lineage to the crown, and the fact she was truly beautiful.

"Either way, I am glad our son is finally smiling and laughing at his own birthday party. Now, about that one that Fairy Tail wants to throw for him next weekend on his real birthday," she asked.

Lahar tensed and shuddered physically. Because he didn't want to think of the crazy that was her guild. Laxus and Erza were married and ran it with an iron fist, damages were down… mostly. Natsu and Freed married and had a child together with Lisanna Strauss as the surrogate that became their mutual wife. Agni was a mini demon who had an odd mix of all his parent's magic. Mostly the Slayer though and that was gonna be a problem due to him taking after his pink haired father.

"Can we talk about it later? I would rather take you on the floor and show everyone who you belonged to. I am tired of these leeches ogling my beautiful treasure," he said, grinning down at her.

"Oh? Possessive much?" Lucy quipped back at him.

"Damn straight, your my lucky treasure and a one in a million, once a millennial kinda gal. And you only get more gorgeous every day of every year, Lucy," he stated as he led her to the floor. Not caring how smug he looked as he spun her out and back into his arms and danced with her.
