Who Made Me Athanasia's cousin?

Rumors about Jennette

Jennette's P.O.V
" Cousin Jennette!" I look over and see the fake. "I don't have time for you!" Her eyes start to water. I don't care. " Cousin! Are you mad at me? Did I do something wrong?" I glare at her. "Yes you did! You ruined my party!" she looks at the ground. " I'm sorry that I made you upset."
" Shut up! You're nothing but a bastard child! Are you a fool? I never consider you as my cousin! You don't deserve the name Ambrosia!" I slap her and walk away as she's crying. When I get back to the Ruby Palace some the maids give me weird looks.

Ambrosía's P.O.V

I hear the things said by the maids about  Jennette so I decided to make her reputation worse. I knew that she would react that way, that's why I went.

" Imperial Cousin? Can I come in?" I ask, my voice shaking " Yes.".

" Athy!" She hugs me and I hug her back.  "What's wrong? Why are you crying?" She  wipes my tears. " I went to visit Jennette to say sorry and she slapped me. She said that I am a 'bastard child' and I don't deserve the name Ambrosia." 
"How dare she! I'll talk to her, you stay here."
The maids start whispering, "To say that to a child who hasn't had her coming of age party."
" Emperor Claude must be told."
"How could the 2nd princess say that?"
"She's so mean!"

Time skip two hours later - Athanasia's tea party

"I am the 2nd princess, Ambrosia De Alger Obeila." I bow. Some of the noble girls start whispering.
"She looks like the empress."
"She's so cute!" 
"No wonder why she's the gem of the imperial family." Athanasia sighs. "Sia, sit." I do as she says. "Athy, where is Cousin Jennette?" The girls start talking. "It is rude to not show up."
"I heard this morning that the 3rd princess hit the 2nd princess!"
"Me too."
"How can she be that mean?"
"Sister, I'm here!" Her smile is so fake. "I am the real gem of the imperial family, not this brat!" I wield my eyes to water. "Jeannette! You can't speak to her like that!" Athanasia says.
"The Crown Princess is right, 3rd princess."
"Princess Ambrosia has been kind to you." The girls all speak up for me. I smile. "There's no need to be mad, cousin is probably still upset about what happened in the Ruby Palace. Also, I can't reach the tea Jennette. Since you got it for the tea party, can you please pour me a cup?" I flinch when Jennette glares at me. "Yes, 3rd princess." She pours me tea and I take a sip. See Jennette, all this belongs to Athy and I, not you. "Jennette!" Uncle's voice is cold. "Father!" Jennette smiles. "Papa! What's wrong?" Athanasia looks worried for uncle. "Blessing and glory to the sun of the Obelian Empire!" The girls bow. "Take a seat." The girls sit down. "I heard that you broke that portraits of Empress Diana and Ambrosia's mother!" I start to cry. That was the last thing a have of my mother! "May I go back to the Emerald Palace?" I ask uncle. "Yes." I run away, not seeing Jennette smirk. I fall, head spinning. When I land on my knees, I throw up blood. It was poison. At least I got it instead of Athy. I black out.
