Ah well. She'd just go with the flow.
Melanie shot after the other Lockhart as he zoomed past her, lying flat on her broom. She went into a dive, flying after the Ravenclaw girl and Treyen with intentions to snatch the quaffle out of the air as the girl (Vashti) dropped it. She pulled out of the dive just as soon as she went into it though, carefully dodging one of the blooders as it passed by.
Her eyes widened as she realized some of the rocks serving as blooders were looking a lot bigger. Suddenly she was very grateful for the helmet and bulky padding provided by the Professor.
Melanie flew higher and higher up. Then, when the quaffle started flying toward one of the baskets...
...Well, she reached out and grabbed it by it's strap, intercepting the ball before it could enter the scoring area.
Then Melanie zoomed in the opposite direction, toward the hoops on the other side of the field at top speed. Unfortunately, just as she got about midway, Melanie had to dodge another of those bloody blooders. As she swerved to avoid the mini boulder the quaffle went flying toward the ground once more.
Better it than her.
