The same day that she had seen Catalina in the hallway and ignored her, Blair decided to talk with her to address the issue, she means 'Yves'. After lunch, she knew that Catalina will go to the library since the next hour is vacant for Catalina's class. It maybe sounds creepy but she got Catalina's schedule memorized just by observing the girl.
Blair has a class. She only had a 'long quiz' for the whole period so when she finished answering the quiz, she asked her teacher if she can go to the restroom but the truth is she will go to the library instead. Luckily, her teacher let her since she's done already. She only has less than 30 minutes to get this problem solved, thanks to the commercials before they started taking the long quiz. Blair sped up her steps and made it bigger than usual
