Alex watched in despair as when she finally neared Snitch, he changed directions, taking a sharp turn towards a boy in Gryffindor robes, perhaps? Alex wasn't really sure, she couldn't pay much attention, after all, she was chasing a pup going over speeds of 100. At least, that's what it appeared to Alex' brain.
Shouting an apology to the person Snitch had knocked over, she desperately dived, landing on the boy in whose direction Snitch had run off to. "Gotcha!" She cried triumphantly, as she rolled of the boy, holding the squirming Snitch in her hands. "Sorry," She apologized, "Had to be done." She said, as she glared an evil glare towards Snitch.
