How had she missed the fact there was a spider in the ingredients? She'd have to drink this? Seriously? Not like it was a candy confectionery, it was REAL. You did NOT eat real spiders, especially not after Cassia's little brother killed their darling Venom. Poor tarantula, never stood a chance with the idiot...and her idiot of her cousin as she'd heard it.

If she found she couldn't drink it then she was most likely gonna feed hers to a firstie and record the data afterwards. How would Collarbin know? Unless the kid squealed but she figured she could take care of that.

With some reluctance, Lex added the spider. Next, according to the board, was the crocodile tooth which she added. For maybe a minute or three, she stood there waiting until she heard the potion grumble, then she added the second. That was it then, right? Done with the potion until it matured? That was most likely the case given they were cleaning up. It didn't take the Gryffindor long to get everything scourgify-ed. Idly she wondered why some bothered with the wash basin but to each their own, yeah?
