#1.3
After shoving Albus back out to the corridor and bidding Malfoy a hasty goodbye, Rose followed his now-curious cousin back to their original compartment. He slowed down his steps purposely and not-so-subtly glancing to her.
"Why were you sitting across Malfoy, Rose?"
Rose sniffed, and pushed her cousin from behind to walk faster. "Because there were no empty compartments left, and Merlin knows I can't read with all of you yelling."
Albus placed a hand over his heart, and put on a wounded look. "So you left us for a book? I'm hurt, Rosie!"
Glaring, she smacked him lightly over the head with her book and placed her hand on the door to someone's compartment. "Yes, I did and I would, again," she resumed their walk, "how did you notice that I wasn't with you anymore though?"
He rubbed the top of his head, ruffling the already messy black hair. "After James asked for your opinion a few times and nobody answered," he took three long strides to be back beside her, "got to say your sneaking skill has improved, Rosie."
"It wasn't me being stealthy, it was you being oblivious when it comes to Quidditch." She was a bit curious though, on how Al managed to guess where she was, so then she asked, "how did you know I was in Malfoy's compartment anyway?"
"Easy," the middle Potter grinned and gave a thumb up. "Just listen to the noise and sneak a peek — his compartment is one among the few quiet ones in this part of the train."
Quite satisfied with his answer, Rose just nodded and pushed the door to their compartment open. Knowing Albus, it wouldn't be the last time he'd ask about Scorpius (whom she hadn't even known aside from his name), but until then, she'd just let it go. And maybe he'd forget for the time being.
