Flynn was quiet but it was in an obvious kind of way. His introspection was visible on his face and the ever-growing fourth year barely registered the existing occupants of the room when he first stepped inside - not the new teacher person, and not even his pre-Hogwarts primary schoolmates. He didn't notice what was on the board either so it was lucky when the unfamiliar adult voice telling them to grab goggles and an apron said it out loud. Flynn doubled back to grab them and then joined Fifi at her workstation.

He put the apron and goggles on, careful not to mess his hair up and then just kind of stared at the cauldron. Cauldrons were great for staring at. You could imagine all sorts of things in their depths.

Hey, at least he was here!
