In the HSM series, Jason Cross is part of Troy and Gabriella’s homeroom class. He is also on the East High basketball team and is very close friends with Troy and Chad. He is the jokester of his peers and always seems confused and out-of-the-loop. Throughout his
junior and senior years, we see Jason mature a little bit. However, he never looses his fun, care free personality.
In HSM 1, we meet Jason as the kid that falls asleep in class and the kid who asks random questions. We laugh at him and his silliness. He becomes more serious however when he and his teammates find out Troy is trying out for the school’s winter musical. Jason and the rest of the East High basketball team think that Troy should be devoting all of his time and energy into their upcoming championship game, and not singing with some girl. They come up with aplan to stop him from singing which backfires and drives Troy away from them. In the end, Jason and the rest of his peers learn an important lesson that friends should let each other be whoever they want to be. They should enc
ourage, not deter, each other from trying new things and being the best person they can be.Â
In the summer before Jason’s senior year, he gets a job working with a lot of his East High friends at Sharpay’s parents’ country club. He is assigned to be a waiter along with Troy. When Troy starts getting a lot of attention from Sharpay’s parents and the University of Albuquerque basketball team, Jason and some of his other teammates start feeling left behind. Troy seems to be forgetting them and all of their plans for the summer because he has this awesome opportunity. In the end, Jason and 
his friends are able to help Troy set his priorities straight and finish out the summer having a great time.
In their senior year, Jason and the rest of his East High classmates are signed up (against their will) for the musical. At first everyone is very hesitant to participate, but in the end they all agree to make it one of their last memories together in high school. Jason has lots of laughs with his friends as they are practicing for the musical, even though he is way outside of his comfort range. At the end of the musical, all of the seniors step forward with their diplomas. None seem as happy as Jason to be graduating.
Were all in this together
