Sir Nicholas floated into the Great Hall about the time Headmistress Hawthorne's speech began. It would be most terrible form to draw attention to himself in the middle of the speech, so he hovered near the wall, applauding at all the right moments.
When she was finished, he glided the rest of the way toward the Gryffindor table and his noble Lions.

He hovered above the table, blinking in surprise. Oddbodkins, things were certainly quiet this evening! Perfectly understandable, given the circumstances, but the relative silence depressed the ghost's mood nonetheless. He missed the sounds of laughter and conversation!

"Greetings, Gryffindors!" he said, giving all at the table a deep bow. "And friends," He added upon noticing the young lady Quinn.

Sir Nicholas spied the Head Boy. "Hello, Ronan! I do believe congratulations are in order. The best of luck to you, and may you look back fondly upon your time in the most noble house of Godric Gryffindor!"

He raised his voice to address the rest of the group, "Congratulations and many thanks to all of you as well! Your heroic efforts against the Inferi will be remembered through the ages."
