Teacher's shared office

Helena, Darrel and you started with professor Mirabelle office. As long as you where here in the professor form, nobody would find the presence of student strange.

Time is running and you did not find yet the gradding papers. Now you are headed to the professors shared office. You enter first, and after finding out the room empty you let your friend in. The more you are, the faster you search. But this time you are more cautious as you would not find a proper excuse for the presence of student here. That's why Darrel is in charge of keeping watch.

After a while you finally find the papers. With a quick wand twist you change the grade. Mission accomplished
