How would Hermione react to getting a howler from Annabeth in the fanfiction?

He might be initially shocked. Draco is used to being the one in control and having others be intimidated by him. A Howler from Percy, someone he may not have considered a huge threat before, would be unexpected. He could be angry and vow revenge in his mind.

Harry might immediately gather his friends and share the contents of the Howler with them. He values their input and they've always been there to support him. Together, they would analyze the message and come up with a plan. Maybe he'd be a bit angry too, feeling that Voldemort is always trying to disrupt his life and the safety of those around him.

He might be initially shocked. After all, getting a Howler is a very public and embarrassing thing. He could be so ashamed that he immediately hides away to read it privately, his face turning red with a mix of anger and humiliation.

Hermione could be very hurt. She respects Mrs Weasley a great deal, and to receive such an angry message from her would be a big blow. So she might cry and isolate herself for a while to think about what she did wrong and how to make it right.

In some fanfictions, Sirius might use it as a chance to show off his independence. He could read the Howler out loud in front of his friends, laughing at his mother's old - fashioned views. This would show that he doesn't care about her threats and is proud to be different from the rest of the Black family.

Well, it depends on the context set by the fanfiction author. It might trigger a conflict or a new plotline. Maybe it reveals something unexpected about Annabeth or changes the dynamics between the characters.

Well, it could be that Draco did something to cross Annabeth in the fanfic's plot. Maybe he messed with one of her plans or said something disrespectful about her friends.

Their friends at Camp Half - Blood would be overjoyed. Grover would probably be dancing around and playing his reed pipes in celebration. The other demigods would see it as a sign of hope, that love can thrive even in their dangerous world. They would start planning a huge party with lots of food and games.

She'd probably be shocked at first. But then her face would light up with joy. After all, she and Percy have been through so much together.

He might be very embarrassed. Howlers are known for delivering their messages in a rather loud and public way. Draco, who is used to maintaining an image of superiority, would find it humiliating to have his family's business aired out in front of his classmates.
