[This scene is NOT mine.] Ron had so much confidence from thinking he had drunk Liquid Luck to win the Quidditch game against Slytherin, that they did win. Ron did really well in that game, and you cheered him on.. even though, you knew Lavender Brown liked him too. After the game, a lot of kids in Gryffindor, and others who were Ron's friend, came to celebrate. "Weasley! Weasley! Weasley!!" They all cheered. You looked away for one second, and back at him, and you see Lavender and Ron kissing.
