"I see. Mr Charlie" Billy says, turning back to the spirit "I regret to say that I can not stay longer to speak with you. I have a, friend, I think, who is in desperate need of help. I have wronged this person, and need to make up for it. Please, call on me if you ever have any problems or if anything strange happens, and pass it around to all the other ghosts that Billy Bishop always has time to listen. Thank you, sir."
Billy gets up to leave, turning to the professor. "Thank you, master, for teaching me." He then leaves the room, He wonders if he should attend Mr. Bone's class, But instead heads for the wind dorm to Look for Mr. Ashgrove. He doesn't know what he plans to say, but he is a diplomat. He will think of something.
Unfortunately, Eric is not in the wind hall. He taps a passing wind student.
"Excuse me, hate to be a bother, but do you know where Eric Ashgrove is. That's Ashgrove, not Ashcroft."
