Liz looked puzzled- she'd heard the bludger whizzing around for a moment, then it got fainter. That could only happen if... she realized a second too late that it would be coming from above. She didn't have time to pull back and swing at it, and she couldn't pin point exactly -where- it was coming from aside from 'up'.
Liz held up her bat, above her head, with both hands. She might be able to use that to make it bounce away.
A split second after her bat was held up, she felt the bludger coming towards her, several inches away from where she currently held the bat.
Liz quickly swung the bat forward with both hands, hitting the bludger dead-on with the bat sideways. It flew at George. She grinned, and swung her bat into one hand, ready to hit it after George did.
"Well," Liz began, "Courtney, Bella, and I decided to go out into the forest and wander. We ran into a cougar." she felt bad about lying to him, but until she'd talked with Courtney about this, it was the story they'd stick with. Maybe she could tell him later.
