Mona is using a compact to both check her lipstick and spy on Hanna, Aria and Emily. She slams it shut and the music seems to think that's a BFD. We head over to the Liars who are freaking out because Spencer is a no-show for school, even after an SOS text from Emily. Hanna tries to calm everyone down. Emily says that if Spencer doesn't respond, they'll go to her house after school.
The bell rings and the girls take off. They are stopped by someone I'm guessing is the principal. (S: LOL, look at him, pretending to have any authority at this fake school.)
