Since Kyle dislikes being around with too many people, Alfonso rented a private plane to ride on. And before they got on the plane, Alfonso pulled Kyle on the side, and reminded him, "Kid, I know that you're being way too childish with your jealousy, but don't you dare make any weird things to my son, okay? Or else, Anna will hate for the rest of the trip."
Knowing how fond Anna is toward his son, Alfonso is sure that Anna will get angry if Kyle ever happens to pull some weird tricks. That is why he is here now talking to Kyle to warn him about that because Anna wouldn't let anything slide just because she likes Kyle.
Kyle stayed silent for five seconds and thought about it, he did not want Alexandre to be with Anna way too much and he does plan to make separate the little guy away from Anna, but he does not want Anna to hate him for the rest of the trip.
