"Knowing things always requires time and research. I rather stop whatever that's trying to kill me first and then worry about knowing things." It had worked for him until now, no reason to change it." He stopped and turned to Malfoy, probably not a smart idea after he had recommended that they pay attention. "And Hogwarts doesn't allow Apparition, until it does. Hogwarts doesn't let unwanted people in, until it does. Hogwarts does what Hogwarts wants."
He turned around and kept going up, his goal getting to the second floor and the entrance to the Headmistress' office. "I'm still alive, aren't I? I don't know why people think you need all this fancy magic when you can usually stop people with basic first year spells. The rest is just for show or sadism. Same with the wands. We like them because then we don't look as stupid as if we waved our hands around."
He grinned when he saw a ghost coming their way. "Sir Nick, how are you? How's the Headmistress?"
"Rather dead, my dear boy. Terrible thing it was, but that was years ago, no need to fret about that. I explained to your friends , they are here as well. Ron is somewhere around here, Narcissa too, so many visitors. It's rather refreshing. The ghosts have decided to have a party in your honour and now we have two more guests, how splendid," Sir Nick answered before going away.
"What the fuck?" Harry said. "If Ron's here, we should find him, and why is he here with your mother?"
