'I heard that the twins are missing, I do not know any thing on that but, I saw the house elf Argyle down in the dungeon corridor when I was going to the Slytherin common room. She was shaking her head and then disappeared. I do not no if this is any help. I would looked around but I did not know if I should or if it was safe or not, so I thought I should come and tell you what I saw. Oh, I am a parselmouth so if you would need some one to talk to the snake around here about what they may have seen let me know', Mystie said
