Okay, so the moment his fellow students Disillusioned themselves, Adi found it hard to keep track of them. Obviously. They blended in with their surroundings. He then decided to hop onto one of bigger stones so he took his time in doing so. Maybe from high up he could spot some give aways?

Ugh!

It was toooooo quiet. Not even a sound of a twig cracking, stones tumbling or rustle of leaves (save for the wind). Staying at one place was NO FUN. Adi jumped down from the stone, making quite a bit of noise on purpose. But it was too late for anyone who came to investigate for already he was carefully making his way unknowingly towards Yoongi.

Adi stopped a few paces from his, listening. All he could hear was the breeze. Hmph. He swung his eyes here and there looking for any disturbances in the surroundings but so far nothing. Nada. Zilch.

Since all was so quiet, he decided to take matters into his own hands. ''Homenum Revelio!'' Ahh, the advantages of being able to cast non verbal spells... no one could hear him.
