Luke continues to look around in the strange room, waiting for Sir Cadogan to return. He sits down in the empty room and watches as Sir Cadogan gallops through six paintings before he finally stops at his favourite painting. It's true, isn't it? Everyone is gone...there's no sign of anyone in this castle now.
Good lord, this is real weird...but there are still places where I can't go as long as there isn't any paintings on the walls, Cadogan explains.
Well, I don't even know what exactly happened...but anyways, where am I? This doesn't seem like any ordinary room. Luke asks curiously.
You are in one of the safest places in Hogwarts! Look at those 6 other paintings...behind them lie secret passages leading to various locations around Hogwarts and one of them...leads you right out of Hogwarts and straight to the Ministry of Magic! All you need is the password and I'll open it for you... Sir Cadogan says as he gallops right to the painting of a silver dragon.
But I don't know the password!
No password eh...what is your name, young lad?
Luke Night, sixth year in Gryffindor...is that what you need to know before you give me the password?
No...I just trying to know you more..since you're going to stay here for a long time...
