Kyle arrives at warriors, the green lantern lounge to find it in shambles. He finds a beat up Guy and John who tell him parallax destroyed the place looking for his younger self. We flash back to what happened earlier with Parallax fighting John and Guy, guy uses his Vuldarian power and John those strange bursts of green energy. Guy saves John when he realizes that Young Hal and Parallax are two different people as strange as that sounds, he tells parallax where where to find himself and then they have a finale duel. Parallax won and flew off for the watchtower on the moon.
Kyle decides to stop parallax before he reaches Hal, on the watchtower Jonn and Hal wax philosophical about starts before Jonn departs for his quarters leaving Hal to the stars.
Kyle reaches Parallax and they fight, though parallax doesn't remember Kyle, he's from a time before he met Kyle or was defeated, he's come to return Hal to his proper time so he can ensure his existence. Kyle realizes the gravity of the situation, if he stops parallax, Hal doesnt destroy the corp, he doesn't get the ring and worst Hal never dies reigniting the sun thus saving their universe. Kyle calls a truce but Parallax knocks him unconscious so he can finish his job. Just then Young Hal arrives ready to fight Parallax.
