In many fanfics, Fleur is often depicted as strong - willed. She's a Veela, so she has that alluring quality, but she's also smart and not just a pretty face. For example, in some fanfics she uses her Veela charm in a strategic way to get what she wants or to protect others.
Peeta could be the one to save her. He has always cared deeply for Katniss. He might gather a group of rebels secretly and launch a rescue mission. Maybe he'll use his charm and skills to infiltrate the Capitol and find where Katniss is being held.
Gale might also attempt to rescue Katniss. He's her friend from District 12 and is quite skilled in his own right. He would be furious to hear that Cato has kidnapped Katniss and would likely gather resources and allies to try and save her.
Her character could develop a new level of determination. Before, she was fighting for her family and district. Now, with a baby on the way, she has an even greater reason to survive. She might become more calculating, using her wits to avoid dangerous situations rather than charging in head - first. She would also probably show more vulnerability, as the pregnancy adds an extra layer of stress and worry.
Katniss would likely become more protective. Her natural instinct to survive would be amplified by the need to protect her unborn child. This could make her more cautious in her actions in the arena, but also more fierce when directly threatened.
She might get angry. Katniss has a fiery side, and seeing Peeta with another girl could trigger that. She could give Peeta the cold shoulder and refuse to talk to him.
Fleur Delacour is a character from the 'Harry Potter' series. She is a witch from Beauxbatons Academy. She is known for her beauty and her skills in magic. She participates in the Triwizard Tournament and plays an important role in the story.
In many fanfiction interpretations, Fleur's response would depend on how the author has developed her character. If the author has portrayed her as more open - minded and adventurous, she might quickly accept Harry's invitation with a smile. But if she is depicted as more cautious or reserved, she could decline politely, perhaps stating that she already has other plans or that she doesn't think it would be appropriate given the inter - school dynamics.
It could be Charlie. Since Charlie works with dragons in Romania and has connections in the wizarding world, he might be in France for some dragon - related business. He knows Bill well and also has some acquaintances in Beauxbatons. So, he could introduce Bill to Fleur at a gathering of international wizards.
