She had just been hesitating, the incantation for the cleansing charm on the tip of her tongue, still too reluctant to use her wand, when someone else did it for her.
Rika gawked as Vivianna took out a vial full of some thickened liquid, uncorked it and dipped her fingers in it. Those potioneer-hands stretched out towards her, and Rika understood too late: Vivianna meant to apply it herself.
The fingers skimmed on her wound, and Rika executed a full-body flinch. To anyone else it would appear as if the paste had stung and Rika simply had a low pain threshold. But her calf muscles clenched and unclenched, her legs were quivering, and she had to curl her fingers into the earth to prevent herself from slapping off Vivianna's hands. A witch like Henri Finch already knew how much she loathed, no feared touch.....a Slytherin didn't need to know it too.
Hold on. I know you can do it.
The scream that had been swirling in her throat, barely held back, died when those hands suddenly withdrew, and she let her legs collapse, fall flat on the ground. Her mind had already started spinning excuses for her behaviour, when she realised that no questions were hitting her eardrums. She raised her head, and gawked again at Vivianna, who appeared to be banging her head against a tree. It was a rather refreshing experience, to be able to stare at others and contemplate their weirdness for a change.
"What on earth are you doing?"
