Percy was working. Or doing the best he could to work. What, exactly, the duties of a lawn boy entailed, no one cared to explain to him. He did ask.
With no given answer, Percy decided that a lawn boy must try to keep the lawns and general landscape looking.. neat and orderly. Weeds would not be tolerated. The shrubbery should be trimmed. If a plant's leafy fronds were hanging too low, they needed to go.
As such, he was wandering about with a pair of scissors for lack of better equipment to utilize for the tasks he set himself on. He was crouched down, clipping a stubborn weed, when a shadow fell over him. Looking up, he recognised the young face of a Mr. Anthony Goldstein. As Prefect and Head Boy, Percy had taken it upon himself to learn the name and face of every student under his surveillance.
"You've been taken away from that point in time," Percy explained, straightening up to stand. "I don't know how, nor why, but most of us are in a similar state of utter confusion."
