"Come on now, I've no time for shirkers. Say 'UP'. 'UP' like you mean it."
-- Madam Hooch (CC1.4)
Madam Hooch teaches the first flying lesson to the first year Gryffindor and Slytherin students. Rose Granger-Weasley and Yann Fredericks both are immediately successful commanding their school brooms. Everyone else manages on the second try, including Scorpius Malfoy, but excluding Albus Potter (who is unable to raise his broom). He is then unfavourably compared to his famous Quidditch-playing father (CC1.4).
