Walden was just setting fire to a nearby store front when he felt a burning tear across his arse. Shielding as he turned in the direction of the assault, he managed to block all but one of the rest, which left a shooting pain in his left shoulder. None of which was enough to erase the manic grin from his face as he hissed with pleasure at the sensation.
His attacker looked at first glance to be one of those uptight, business sort the Ministry loved to hire as Aurors, Walden assumed because they were little good for other entertainments unless one was willing to put in the time to break them. Smirking wickedly, he fired off a volley of his own, an assortment of curses designed for pain and distraction, followed by a length of enchanted ropes.
Nothing that said he couldn't bring back a souvenir if he wanted, after all.
