That was a good question... Theo stared at the professor, then looked at his ingredients. Hummm... He would start with the easiest one first, the glass of water. The Slytherin raised his hand, and taking brief notes as he went along, because he probably would forget. "I have a glass of water, because it is used in pretty much all the potions. Err, you can use a spider for..." He paused, and dabbed his quill up and down on his parchment. "I think you can use the spider legs for something." He wrote that down, even if it was brief.

The next one, he knew something about. "I know that nettles can be used in the Cure for Boils." Theo had looked that up one time because he had thought about giving Alice boils one day, but chickened out in case he got caught. The cure potion looked way too hard. And the last of his ingredients, daisy roots. He was sure that they had used them before.

But what was it for?!

OOH.

"Shrinking solution! We used daisy roots in that potion once, I think." He said, writing that down, too. Once he was done, Theo rested his quill neatly next to his parchment and smiled up at professor Lafay.
