Cho heard his barely audible words about an invisibility, and gave a nod, disillusioning him just as she got through the checkpoint.
It didn't take long to get to his home, bringing him up to the porch as she quickly released the spells. She heard a gasp, and tried to hold him up. "You be right from here?" She asked, realising now that he might just talk. All these years of keeping her identity a secret.
Her mask was off, but flying back home, nobody would really notice. "Oh, there's just one more spell," she said as she reached for the door.
"Obliviate." She didn't need to do much to obliviate his memories of the past few hours - he'd bee half delirious.
Quickly, before he got his senses back, letting him head into his home and fled. She did hope he'd get that wound looked at more. It was nasty, and she'd done all she could.
Cho was exhausted, and it took the last of her energy to hop onto her broom and get home. The Remorseless Dragon was very tired, and needed rest. She didn't get to kill anyone, but Higgs owed her - big time.
