Being at Hogwarts was terribly bittersweet for Neville. On the one hand, he had loved this castle more than just about anything. On the other, it had also seen quite a number of tragedies. The only reason he was able to come back now, like he had been able to return for the repeating of his final year, was to remember that the good time outweighed the bad. Of course now that seemed to have been turned on its head. As he walked down from Professor McGonagall's office, he couldn't help the faint trace of a smile in the corner of his lips as he remembered those good times. He had come to talk to the Headmistress, more for himself than anything, but it was good to see her again. It was on his way out of the castle that he noticed the girl sitting on the floor against the railing. For a brief moment he thought it was a student, until he was a few feet away and realized it was Lavender. He paused for a moment, wondering whether he should sit or stand to talk to her, though his body made the decision for him and sat beside her.
"Knut for your thoughts," he said quietly and nudged her with his shoulder. Neville didn't expect many people to be in good moods. He expected there to be a lot of tears at the funeral, and a number of people who would feel completely lost. It was a feeling that Neville had some experience with. Part of the reason the DA had been revived. People needed hope.
