Astrid was shocked to see the Professor's lesson was being interrupted. How rude! She thought silently.

When the cookies were passed her way she took one and passed the basket on. She still remembered the last time she had eaten one of these cookies. This time she'd just pretend to eat for a bit to buy some time until she could see whether or not any of the girls start acting weird again. The idea of being drugged, whether it caused ill-affects or not, really freaked Astrid out.

When she heard Professor Lainey's warning, she was relieved that she had hesitated about eating the cookie. Something was going on here and she had NO idea what it was.
