Katie was thrilled to finally be out doing something that wasn't quidditch practise, though she was also more than happy to be on her broom despite this having nothing to do with quidditch; Katie was more at home on her broom than anywhere else in the world.
As much as she hoped they would find something, anything, she didn't want to admit that she was equal parts nervous and doubtful, nervous that they'd have to fight (and the last time there'd been a fight, lots of people had been lost, including Fred, which she refused to thinker she'd start crying, which she was sure wouldn't be appreciated by those around her) and doubtful that they'd even find anything (wouldn't Harry and the other aurors have found something by now if it was this easy?) at all.
Pulling her broom up next to Oliver, she leveled put beside him, keeping her eyes on everyone they were flying with and the ground they were moving over, a skill that she used without even thinking thanks to years of quidditch. "Oliver," she said, loud enough for him to hear through the wind, but hopefully quiet enough not to bother anyone else.
