I planned on being in the class, but it being lead by Roark instead. I plan on giving Issac an obsession with fossils to cause him to become obsessed and start experimenting and such, being he has a fossil of his own. I can hold off on it until later, though. Mythology can spark the interest. Or maybe Roark can pull Issac from the class. I don't want you to have to go through any unnecessary trouble, though!
