Harry Potter and the Chamber of Secrets2002

[In the Gryffindor common room, the Gryffindor students are talking with each other when McGonagall walks in holding a scroll.]

McGonagall:
Could I have your attention, please? Because of recent events, these new rules will be put into effect immediately. [Reads the scroll] "All students will return to their house common rooms by 6:00 every evening. All students will be escorted to each lesson by a teacher. No exceptions." I should tell you this. Unless the culprit behind these attacks is caught, it is likely the school will be closed.

[McGonagall walks out. The students resume talking with each other. Harry turns to Ron.]

Harry:
We've got to talk to Hagrid, Ron. I can't believe it's him. But if he did set the monster loose last time, he'll know how to get inside the Chamber of Secrets. And that's a start.

Ron:
But you heard McGonagall. We're not allowed to leave the tower except for class.

Harry:
I think it's time to get my dad's old cloak out again.
