It was a little reminiscent of the whole Loki - Thor relationship from Marvel. Certainly not a traditional MOTU action and battle story. I think it doesn't win any fans for Miro and, to a degree, Randor. I wish the writer and the characters would have spent a little more time on why a half Gar king is a bad idea rather than just flatly accept it as a matter of fact. You're the king Miro, you can change the law! Their whole stance is just like saying a black gay woman can't be president because we've never had one.
Another thing that would have helped the issue is a little more backstory on just what Keldor did! "You betrayed us" is all we got. How horrible was the betrayal and damage?
