Felix Felicis

On the morning of the Quidditch match, Harry secretly pretends to add Felix Felicis to Ron's pumpkin juice to boost his confidence. Ron plays brilliantly, saving every goal, and Gryffindor wins decisively. After the match, Hermione confronts Harry, accusing him of using the potion, but Harry reveals he did not actually use it; Ron's success was his own. The victory celebration is marred by Ron's new relationship with Lavender Brown, which he flaunts in front of Hermione. Hermione, hurt and angry, attacks Ron with a flock of conjured canaries before storming off. The incident deepens the rift between Ron and Hermione.
