Evan, with his tail between his legs, is quiet for most of the week, though not happy about it. He does his practicing primarily during the day, or outside in like, a field or something so as to avoid Nadine and Rahne's collective wrath. By Friday, though, he's gotten his mojo back and is back to his old habits.
He was also at Antoine's all four days of Aoife's stint, and applauded when she announced her support. I'm assuming his claps were drowned out by the booing, but he was openly cheering for her without caring who saw him.
Also, he sent a copy of the book back to his old nanny Ruth, who taught him everything he knows about Aurelle.
