When they arrived to Auradon him and Carlos were fighting over something blue and he noticed Audrey and he maybe fall in love with her. He later when they were in the museum tried to get the wand by foolishly reaching his hand out to grab the wand even though their was a force field around fairy godmothers wand and despite Mal shouting at him to not put his hand near the force field he did so and that set off a siren signalling the museum guard to awake and investigate the intrusion and what was the cause of the siren going of and the villains kids were then forced to make a run for it but Carlos lied on the phone to security telling them it was a malfunction in the brethren circuit and the siren was then turned off making the guard return to his working post where he was originally. Carlos was then called by Mal to hurry up and he haughtily said in a moody sarcastic voice " Your Welcome" and the kids ran of back to the school with mal complaining to Jay " way to go Jay now we have to go to school tomorrow". the next day he joined the tourney team with Carlos who he found extremely gorgeous in his tourney Uniform and Carlos. When he started tourney he became the best tourney player of the team and Coach Jenkins was extremely impressed with him and asked to sit down with him later on talk about the rules but he was very impressed with him nonetheless.
