Luna walked alongside her professor as they approached Ravenclaw Tower. Luna didn't notice that they weren't speaking, she was far too caught up in her own head. She was thinking of the ghosts, the paintings, the virus, and different species of animals. As they reached the tower, Luna waited for Septima to go in first. It certainly wouldn't be appropriate for Luna to go headfirst before her teacher!
The office was not a surprise for Luna, she'd been here before. The staff all had nice offices though, and Luna liked to take in each and everyone one of them. Reaching into her bag, Luna plopped her notes on Septima's desk, and waited for the teacher to offer her own.
