Stage Entry
Initial "Something urgent has just come up, so I really need someone to take care of tutoring the kid I usually teach. I'll be waiting in the lower class dorms, so please come see me as soon as you can." -- Klein, Year 2, Class V
1 After speaking with Klein:
  • Klein teaches a boy named Emile who lives in a house near the river south of the Lower Class Dormitory.
  • They were going to go over orbal science. As soon as I've brushed up, I should go talk to his mother, Melinda. It probably wouldn't hurt to go over the history of the Reinford Company, either.
2 After picking all the correct options:
  • That's one tutored kid! I don't think I made any huge mistakes, and he seemed pretty happy with me as a substitute.
