Kingsley ended up fighting the Dark Army the entire time. He had a brief stint with Tabby before dueling Dorian, whom he gave boils. He tied up Dorian, but Dorian managed to have Clara untie him.
Kingsley ended up with a broken arm (above the elbow), but luckily it wasn't his wand arm. He also had scratches on his face and down his back and a bite on his shoulder, but he's going to let them heal the Muggle way because they're kinda badass.
