With Stewart placated, Walker takes Jordan to Odym. There, the reader is introduced to the second member of the Blue Lantern Corps, as Walker and Jordan watch Warth being given a blue power ring by Ganthet and Sayd. After which the two former-Guardians ask Jordan to aid the Blue Lanterns in rescuing Sinestro from Atrocitus, as his survival is important in the upcoming War of Light. Jordan reluctantly accepts Ganthet's request and goes with the Blue Lanterns to the Red Lantern home planet of Ysmault. Along the way, Walker tells Jordan that the Green Lanterns are nothing but a police force, and that Jordan would lead the Blue Lanterns like no other. Though Jordan tells him he has no intention of leaving his Corps, the reader observes Walker telling Warth that it was imperative that Jordan become a Blue Lantern. On Ysmault, Jordan locates Sinestro but is promptly ambushed by the Red Lanterns. He's captured by Atrocitus' forces, and though Atrocitus tells Laira that Jordan's flesh and blood belong to her, her attack is interrupted by the arrival of the Sinestro Corps. Chaos ensues, during which Walker and Warth come to Jordan's aid. They are shown not only boosting Jordan's power, but also capably handling the two battling Corps. Warth easily keeps the two from fighting one another, while Walker keeps Atrocitus himself at bay (though admittedly is unable to douse his red fire). During the conflict, Jordan seems to be able to appeal to Laira's true self despite the red power ring's control on her. Any true reversion of its effects are halted as Sinestro kills her. Outraged, Jordan attacks Sinestro and is so overcome with rage that Laira's red power ring chooses him as its new host. Atrocitus welcomes him to the Red Lantern Corps. Despite Walker's claim that the power of the blue light is the greatest in the spectrum, Atrocitus reveals the weakness behind the Blue Lanterns: hope is nothing without willpower to enact it. Walker concedes that with Jordan's green power ring inactive and no other green aura influencing them, he and Warth are reduced to the basic abilities of flight and aura projection. Despite his disadvantage, Walker holds true to his earlier assertion that Jordan would join his Corps as he places his own ring on Jordan's hand. The red power ring is destroyed, and Jordan is released from its influence. Feeling their powers drained by the coalescing blue energy, the Sinestro Corps flee.
