Sinestro #12 THE JOKER

There's a traitor in the Sinestro Corps who has set New Korugar on a path to certain destruction! The smart move would be to evacuate the Korugarian refugees from the planet, but Sinestro knows finding the identity of the traitor is more crucial, which leads to an unexpected betrayal from someone you would never expect, and a punishment from Sinestro that will alter someone's life irrevocably!
