Dean had spent the night at Lavender's flat the day before the ministry attack. Hours had passed by slowly as he felt himself pace back and forth, while checking the time every so often. It wasn't a pattern that he had meant to continuously do, however, it was unavoidable at that moment. He wasn't going to lie to the fact that the entire event terrified him. They had lost many people prior to that evening. All good people lost their lives that should be around that very day, especially Ted Tonks. A couple of days on the run had Dean almost given up. If it hadn't been that particular wizard, then he surely would have. No matter how he felt about the situation that he was being thrust into, Dean would never think twice about making an appearance that night. After all that he had been through thus far, it was never option.
As the patronus reached them at a late hour, Dean had already jumped into action. Grabbing a hold of his wand, he followed the girl in suit and entered the floo system not too much later. Once he had appeared on the other side, the ministry had already broke out in masses of violence. Dean had set off quickly into the fray to help in anyway he can to take down a couple of Death Eaters. Charms, hexes, and curses had been sent through the air quickly, almost with no precise accuracy
Coming to a stop near Lavender and wand ready, he glanced at her for a moment. "I've got your back. Don't worry," he spoke loud enough for her to hear. Dean knew that she could take care of herself to a certain point, but two sets of eyes watching the other had always been a good idea. After all, what sort of friend would he be if he didn't watch his best mate's girlfriend in such a situation as the one they were currently in?
"Stupify!" he exclaimed before a Death Eater tossed a curse in their direction.
