Pj had taken several minutes to convince Hagrid to let him skip Care of Magical Creatures to study for Potions. At first he was kinda hurt looking to see that he wanted to skip, but after Pj explained himself, Hagrid was happy to let him skip. McGongall was a different matter entirely. She absolutely refused to let him skip. Said that he would need to study just as much for her class as potions and that he should use his class time with her to really figure out what they were doing.
Unfortunately Pj wasn't able to get word to Kayleigh about being an hour later than they originally planned. Once class was over he rushed from his desk, using the charm to have his books trailing behind him. He made it to the library and found Kayleigh in the empty room and he came in with a sorrowful look on his face.
"Kayleigh I'm so sorry, McGonagall wouldn't let me skip and I didn't have enough time to send you word." He rushed a little breathless. His books made an appearance in the room and he grabbed them out of the air and smiled at her.
