The students are informed of the Yule Ball, a Triwizard Tournament tradition, which requires Harry to find a partner with whom to open the dance. He eventually asks Cho Chang, a Ravenclaw fifth-year with whom he is smitten, but she has already agreed to go with Cedric. Ultimately, Harry asks Parvati and Padma Patil to go with him and Ron. Hermione, offended that Ron did not consider her except as a last resort, attends with Viktor Krum, causing intense jealousy in Ron. At the ball, Cedric tells Harry to take the egg into the bath in the prefects' bathroom to work out the clue, but Harry is reluctant to accept the advice because he is jealous over Cho.
