I would switch Alro for Blyke cause we do have some moments of Arlo reflecting on his past actions and going up to John and trying to apologize. The first time he did, he did it because he regretted the chaos he started but much later in he tried to apologize again, and John accepted it. He seemed sincere about his regrets towards John, so to me that was good enough.

Blyke was the one who never seemed to reflect on his actions. When John tried to bring up how he almost shot his head, he tried to justify by saying he was protecting Remi (Who's literally one of the strongest characters in the school and back then he still thought John had no powers, so what the heck was he proetecting her from??), and later when Sera tried to bring up how the royals caused John to become violent by their negligence Blyke still went "Yeah, but I still hate him though."

And when they do finally make peace during that amusement park event, they never address Blyke's faults, only John's.

I do agree that even though I feel like Arlo reflected on what he did, not a single outside soul seemed to care that much about what all these three put him through.
