Cirrus was jealous about Skylar, bc Skyler has a good relationship with his classmates. For this reason they "fought", I don't remember but I think Cirrus say to skylar that he hate him and obviously Skylar was sad (drama moment). today was out the new chapter in which Skylar and Cirrus talk! Cirrus told Skyler that when he see him talk with other people he don't like and dell uncomfortable. Sorry english isn't my first language so I hope you can understand!!
