Experienced, Strong, Beautiful
This, because I was inspired and feeling aghast-y.
Disclaimer: I don't own Hazel, because I am not, in any shape or form the amazing Uncle Rick. Enjoy!
Hazel knew.
She knew she was the youngest aboard the Argo II, and the least experienced (except maybe for Frank, but he was the son of the war god, he could catch up). Sure she could summon some pieces of metal, create wisps of mist that could actually work now, but it it just wasn't good enough. When Jason can freaking fly, Frank can turn into dragons, Percy can control water and create earthquakes, Hazel's pathetic chunks of metal just weren't enough. (Useless, Queen Marie spat in her brain, sitting in front of a glass exhibition of metals that they had cherished and the corpse of the boy across the street who had died because of them. Useless, stupid girl. You can't just bribe the monsters to stop attacking you. With that, Queen Marie stood up, her mystical outfit jingling as she began to imitate Hazel. "Do you want gold? If I give you gold, can you release us?")
She knew she wasn't strong. Hazel could handle herself with her Cavalry sword, but she took one look at Annabeth, swirling and turning, creating a hurricane with her celestial bronze dagger, and she could see why she was the leader. Then she sees Piper, charm-speaking monsters 3 at a time off cliffs and piercing her dagger through some other monsters that was not in her target, laughing in their faces and showering them with insults. And don't even mention Reyna. She had been like the human monster destroyer, leading troops with her pegasus Skippy and tossing anything sharp with a deadly aim towards monsters, in air, while they were still flying. (Hazel thought that she saw a screwdriver flying through the air once and nailing an earthborn in the nuts.) Hazel knew: they were strong. She, however, was not.
And her jewels, oh, her cursed, beautiful jewels. Jewels were used to beautify, but the other girls, they didn't need beautifying, they were already beautiful. Skin tanned and shining with health, messy but still soft hair. A regal sort of beautiful, even when they were mud-caked and scar-covered. But she was not. That was why she had that stupid ability: she needed it. But if only she knew. After the war, New Rome and Camp Half Blood decided to honor the heroes that saved the world and build them some statues for all the campers to see. (Leo had hyperventilated, "I can't do that, I've got a new Festus to rebuild!") But they all grudgingly stood for 8 hours while the Athena and Apollo cabins along with their artsy Roman friends sculpted out some pretty live-like statues. Hazel didn't hear the younger demigods who had said: "they saved the world, they're my heroes forever!", or, "She looks so strong", or even, "she's so pretty..."
She didn't know that she was just as experienced, strong, and beautiful as the rest of them, in her own special way.
