Bea looked at Elizabeth, rather annoyed.

"What, can't I have any fun? The ball is starting and I just want to have a few more moments of fun before the competition starts."
Turning her attention to her brother, she replied
"You don't look to bad yourself 'Prince Victor'."

Next, she leaned in and whispered softly, "You're on pointy." 
She had called him 'pointy', for a long time. It was a joke towards his ears and him being a elf, despite being half elf herself.
After Elizbeth declined the drinks, Beatrix decided she was right.
"I'd love to get some Vi, but Elizabeth is right. We must think of the guests."

Taking in a breath, she attempted to compose herself. 
"Anyway, we don't want to get too drunk and make a fool of ourselves, do we?"

She put on a false smile, and said: 
"We're all equals in this contest right? We have as much chance as any of our siblings do, so let's try our hardest!"

She wanted to say- "I'm going to win this, and when I rule the kingdom, I'll protect it better then father ever could.", but that wouldn't be a very good thing to say, especially to her competition.
