"Hey, look what I got." Harry smiles as he slides into the seat next to one of his friends in the library. "Fred and George gave it to me, but they said I can't tell anyone so you can't tell anyone, okay?"

"It's called the Maraders' map." his voice drops to a whisper, like it was a super secret conspiracy, as he takes out the piece of parchment. "So, like, you say the password, but I'm not gonna tell you that, and it shows you Hogwarts. It's a map that literally shows you every secret passage, and classroom, and person here, isn't that cool?"

He raises a hand to stop whatever question his friend was about to ask. "Yes, it was how I knew you were in here."

A smug grin spreads across his face as he puts the map back into his pocket. "We can explore together, imagine what we can find!" he says a little too loudly, earning a glare from Madame Pince as he sheepishly quietens down. "And since I'm getting extra DADA lessons, I'll protect you if we ever saw any weird creatures in the secret passageways."

He pauses. "I mean, only if you want."
