Draco was pleased to return to lessons, if only because he wanted to see the state of things after being locked away from it - and that had irked him. For all anyone knew he was as loyal as any of the rest of them to the cause, why he was locked away with the rest of the children was annoying - and also because being locked up for a day had left him restless. Of course, there were mixed reactions to the removal of the muggleborn students. Draco couldn't care less. He wasn't Snape's turncoat out of any sense of connection to the mudbloods. He was interested, though, in the new professors.
Derrick? Seriously? But he said loudly enough to his classmates that it was a far better choice than McGonagall, the old bat, and then hung back as the class filed out to greet his former Housemate.
"Welcome back, Professor," he said with a smirk, perching at the edge of the front table where he'd been sitting.
