Very good chapter. Adriar's betrayal wasn't expected, but I wasn't surprised after finding out about Kane. I'm glad he went back to Delta's side at the last moment, and as far as the Exo's moral code goes I definitely approve. You obviously have a plan, but if I'm going to be honest, it might have been more realistic for them to capture Yara and Alpha with the intention of taking them to the City, and then have them escape en route rather than letting go. But again, you clearly have a plot in mind, and my suggestion would make more barriers and might mess your story up, so keep doing what you're doing because it is turning out [i]so[/i] good.
