It was still sort of a damp in her mood that her former Head of House wasn't the History of Magic professor anymore. Serena wasn't the type to grow attached to people (she hardly did), but it was more in a sense of routine. Although she very much adored adventure, when it came to academics she thrived on structured routine.

She was here, though. A sigh leaving her lips as she stepped inside. She still didn't know how to feel about Professor Holden.

"Good morning, Professor." She was polite, though. After her little...incident in Africa...Serena had promised her parents she'd be an angel. As much of an angel an evil spawn could be. So really, there was no promise. It had been something to put them at ease.

Serena Baltazar-Dos Santos was no angel.

On her way to a random desk, she waved at her friends and sat down, her satchel landing on the table with a firm THUMP.
