Ron was practically sleeping on the table in potions, letting Harry and Hermione do all the work - nothing unusual... But he lifted up his head to check the process and only ended seeing a person he didn't know leaning forward to watch over Harry's shoulder as the chosen one explained a few steps of potion making. "Who's that?" Ron asked, his face scrunching up in a way that could be mistaken for disgust, but the boy was merely showing his interest and curiosity. It was weird, yes, but it was a little quirk Harry knew Ron had.
