Sir Cadogan's Advice to Luna
Harry Potter and the Half-Blood Prince
Fifth floor hallway, right hand side...
"Who goes there?"
"Would you be speaking to me, sir knight?" asked Luna, gazing right at the portrait.
"Indeed, I am my fairy lass." replied the knight, "And what brings you to wander about, this dark night?"
"I have just come from the seventh floor. It seems the Come and Go Room is occupied by some horrible people in masks. I saw them and need to warn my friends that they are in danger." replied Luna.
"Quite right, young lady. It is a good thing – to want to help your friends, and I am glad you asked for assistance. I shall help you. Let us notify the other portraits that they may spread the word." said the knight as he mounted the pony and set off down the hall one way, while Luna went the other.
With their help, the entire DA, the portraits and the teachers were able to fight off the Death Eaters with minimal damage. Luna was forever touched to think that they were her friends and that it was okay to ask for help.
