Bellatrix had just enough time to grin down at him before she was pulled down to the ground. She landed rather painfully on her back, and let out a quiet groan. He was good. She was rather glad that she had decided to help him.
Rather than try to get up, she let herself relax, and she looked up at Albus with a smile on her face. Her chest was rising and falling rapidly, trying to catch her breath again. "That was very good. We'll have to try something different for next time." Hopefully he would give her at least a day to come up with something to test him.
