This has probably been done before but oh well; here is my spin on it. I know it's short and not great but it's all I could come up with right now. I haven't written a Potter fic in a while so I hope that this is okay. All rights go to Jo Rowling.
Seamus was thinking of home. He could see the rolling hills of Ireland, where he had grown up. It was so beautiful. He could remember playing with the neighbourhood kids, amazing them with his undiscovered magic. He also thought about his parents. He remembered drawing with his dad and watching Quidditch with his mum. He loved Hogwarts, and England, but if anything else they made him miss home more. He smiled.
Dean was thinking of Seamus. The only person who really knew him, who cared about him; his best friend meant everything to him. After Dean had received his acceptance letter to Hogwarts, nobody would talk to him, not even his family. They had been too scared of him. He had been so incredibly lonely as a first year. And then he had met Seamus; hilarious, accepting, understanding Seamus, and everything had been okay. Dean smiled to himself.
Luna was thinking of her mum. They used to bake cookies, and then surprise her dad with them. They would go out and pick flowers, and then make crowns. They had been so happy. Luna pretended that it didn't bother her, but it did. At least she had dad. She smiled sadly.
Fred was thinking of George.
George was thinking of Fred.
They turned and smiled at each other.
Neville was trying to think of his parents. He could see them in his mind, but he didn't know if it was a memory, or something he had seen in a photograph. Truth was, he didn't really know them at all. He frowned.
Ginny was thinking of the Chamber. When she had woken from her sleep, and had seen Harry there beside her, she had felt the most intense amount of happiness she had ever felt. To know that it was over and that she was safe, not to mention that Harry had put himself in the face of death for her, was enough to make her fall madly in love with him. She looked behind her, and shot Harry her most dazzling smile.
Ron was thinking of two very different thoughts at once. He was was thinking of Dumbledore, in the Great Hall on their first year, calling his name and granting him fifty points for his courage and a good game of chess. He could still hear the cheers of the Gryffindors as they won the House Cup. But he was also thinking of his fourth year, more specifically the Yule Ball. His mind flooded with Hermione, nothing but Hermione, looking amazing in her pink gown. He couldn't help but grin a bit.
Hermione was thinking of the troll. It was because of the troll that she had friends. Nobody had ever liked her before Harry and Ron came along. She had just been that annoying little geek at home and the know-it-all mudblood at school. And now people liked her; she had even had a boyfriend for a bit, and all because she was friends with the Chosen One. She had seen so much, laughed until she cried, and broken nearly every school rule; and she wouldn't have it any other way. She loved Harry like a brother and Ron... well Ron was another story. Hermione sighed in content and the corner of her mouth twitched upwards.
And Harry; Harry was thinking of his parents, of them looking down at him and talking. Just talking.
All at once, they all smiled, as their glittering patronus' flew around the Room of Requirement, filling each and every one of them with incredible warmth.
