Dobby: Terrible things are about to happen at Hogwarts. Harry Potter must not stay here... now that history is to repeat itself.

Harry Potter: Repeat itself? You mean this has happened before?

Dobby: I shouldn't have said that. Bad Dobby! Bad!

Harry Potter: Stop it! Stop it, Dobby! Tell me. When did this happen before? Who's doing it now?

Dobby: Dobby cannot say, sir. Dobby only wants Harry Potter to be safe.
