At night, Ella is grading the test papers at school. She sorts through the test papers and takes out Emily's paper. She finds that Emily has left the paper unfinished. After giving it a thought, she takes a pen and finishes the test for Emily. Just then, she hears a noise outside, as if somebody is watching her.
One of Aria's past indiscretions is fodder for a new "A." A still-shaky Emily tries to focus on school, but could be derailed when she remembers a crucial piece from "that night." #PLL #PrettyLittleLiars
