In elementary school, he met Jeremiah and Mabel, and later in high school, he met Mabel's best friend Jessica. Since Mabel and Jeremiah were dating, Jose and Jessica felt pressured to become a couple, and Jessica controlled everything that Jose does. After they all graduated, they moved in together. However, seeing each other at school and hanging out is very different than living together. Jessica is shown to be very controlling and hot-headed. She doesn't admit it, but she wants to control Jose's life. Jose secretly wants to break up with Jessica, but he's too afraid to ruin their friend group and have Jessica hate him. Jose wants to become an athletic and play basketball, but Jessica may force him to become someone he's not.
Jose is athletic, but is a coward and that influences his way to stand up for himself. He enjoys the outdoors and flirting as well.
