The Principal begins twitching in anticipation waiting for Amon to speak up after he agreed to put him in charge of the Europe field trip.
But what he really wants Amon to address is the situation regarding Caroline.
He has done everything Amon has asked him to do. Harassing Caroline into performing sexual favors for him but never did he go out of his way and stayed within the limits that Amon had set.
It's very frustrating for him to play with Caroline's body and not receive anything in return. He wants to fuck her while tasting her delicious body but he doesn't dare cross the line because he is terrified of Amon.
"Looks like you have something else to say, speak up," Amon sees the Principal twitching to ask him something so he decides to let the old man speak.
"It's regarding Caroline..." the principal says nervously as he doesn't know how Amon will react to him talking about her.
