Okay I'll say it. Even. But I really, really hope I'm wrong cause it would destroy that character a lot. He's very impulsive and act first and think later. It would fit with that he's the one who hurt Yousef, and why the gutta boys got so angry and why Yousef got upset and stayed inside and why Even and Isak was not in the fight. The boy squad assumed it was the ballon squad because they saw them during the song. It would make sense why the lyrics "that bitch is crazy". I hope I'm wrong but idk.
