Jake only smirked. She blatantly realised he was GOOD at potions, so wanted him to stop talking.

It was obvious... well... Jake thought so anyway.

With a jovial smile on his face, Jake checked the temperature of the cauldron and nodded, placing it over the firepit which did not have a flame and pouring the water in. When that was in he started to dice the first daisy root into rather large pieces, as per the instructions, before dropping the bits in one at a time.

Before lighting the fire, Jake took his silver knife and bent low over the second daisy root and painstakingly chopped it finely and evenly into teeeeeeeeny tiny pieces.

"Incendio," the young man muttered to the fire pit, rotating his wand anti-clockwise to make the flame turn low. It was a neat trick.

Picking up the stirrer with his right hand, Jake cast a quick 'scourgify' over it before stirring anti-clockwise 19 times. After the 19th stir, when he started on the 20th, Jake dropped the finely chopped root into the cauldron and finished the final stir, retracting the stirrer when it was at the 'top' of the cauldron.

Watching the liquid continue to spin, Jake kept an eye on his watch, waiting for 60 seconds to go by.

And while he waited...

"What do you think of Mr. Gevrik, Professor?"
