Hide behind Dumbledore

From Create Your Own Story

DumbleDore steps aside and frowns at you. "Are you sure you should stay here, Potter? I'm really considering sending you home...and I don't send students home often here...but you are not the Potter you once were. Don't you remember anything?"

After a while of thinking about this, Dumbledore turns to you. "Potter follow me please, I need to show you something." He walks up the long staircase and into a room full of moving pictures. There are pictures of you... as an infant... with your parents, your real parents! Dumbledore stares at you and waits for you to remember something...anything.

Remember but lie and say you don't and should get home. That he must be sick, you are not a wizard

Look up at him and shout with excitement that you remember it all so well now.

Yell at him to get away. You are not a baby, you can take care of yourself. And anyway you want to look at the pictures by yourself

Stare at the pictures for so long that finally Dumbledore has to force you to leave so you can get back to the sorting hat
