Most of this issue is a fight between Guy Gardner and Arkillo of the Yellow Lanterns. Yellow and Green have joined forces, but some Yellows went off on their own instead, and both teams are hunting them down and offering them a tough choice: join us or be locked up. Arkillo is one of the biggest, baddest Yellows, and Gardner decides to take him on alone, without his ring. Why, exactly, other than to prove how tough he is, eludes me, but it has to do with Daddy issues, apparently. Meanwhile, Saint Walker of the Blues has been brought back to Mogo, GL headquarters, where the two remaining Guardians have a plan for him. We don’t learn what that is yet.
I’m not a fan of fistfights, so this was not an appealing issue for me. Your mileage may vary. And, I’m way behind on this title again, or still, so anyone wanting to read it probably already has, but there you go.
