Seamus Finnigan stunned the Death Eater, and looked up at the sky-
The Giants were sweeping their way across the field, and he saw Dean Thomas kick away an Acromantula.
"Aranea Exime!" shouted Dean, and the spider was launched ten feet away. Seamus grabbed Dean's hand, and pushed him away.
"Run!" he shouted. The Giant stepped and shook the ground, and as they ran, they heard shouts of "Crucio!" and "Avada Kedavra!", and it horrified them. The school and it's grounds were lit not by the beautiful moon and stars, but by the bright green light that signaled destruction.
He ran into the school, and saw Neville fighting alongside Luna Lovegood.
He smiled. They were cute. He felt a stinging pain along his ribs, and then it seemed his very bones were being cracked, every little atom of him exploding and writhing…
He heard a sickening crack, and he dropped to the ground, exhausted.
Dean had pushed his attacker under the foot of a giant, and that was the crunch he had heard.
He shout thousands of spells, and he had seen many things, but he was not prepared for all of this.
He shot one last spell, and retreated to a secluded corner. He was a coward, but he had never seen this.
He saw a spider climbing on Dean- and he sprung forth, and with all his might, he punched the hair spider. Nothing would hurt his best friend- he became a true Gryffindor in that moment, and he saw the Weasley hair streak through the battle field- He saw Harry choke, and their patronuses flutter. He saw two other people shoot their patronuses.
He sighed, hugged his comrades, and kept fighting.
Hogwarts was his home, and it was their job to defend it.
