Who is the last person to see Harry's carriage depart? What is the feeling of this character to see such?

Rose

"And there was one looker-on, who remained with eyes fixed upon the spot where the carriage had disappeared, long after it was many miles away; for, behind the white curtain which had shrouded her from view when Harry raised his eyes towards the window, sat Rose herself. "

"Tears are signs of gladness as well as grief; but those which coursed down Rose's face, as she sat pensively at the window, still gazing in the same direction, seemed to tell more of sorrow than of joy."
