Theory: Gangle is completely wrong when singing: ‘Don't break it Jax!’. It's most likely Kinger that breaks her mask. In both episodes 1 and 2, including this music video, it's actully Kinger that keeps accidently breaking Gangle’s mask. But Gangle keeps thinking that it's Jax that keeps wanna break her mask, probably because he is the one you expect him to bully Gangle, while Gangle thinks Kinger is neutral.
