Episode 4: It's Been a While

In flashbacks, Nolan flies aimlessly through space after abandoning Earth. While contemplating suicide at a black hole, he instead saves a Thraxan ship from it and is made their ruler. In the present, Mark's lingering anger towards Nolan is worsened when he learns of Nolan's new Thraxan wife, Andressa, and their child. Understanding his son's feelings, Nolan nonetheless asks for his help in protecting Thraxa, but three Viltrumite soldiers arrive. As he takes Andressa and her son to safety, Mark learns from her that Nolan truly regrets his actions and loves him. The Graysons defeat the soldiers but are grievously wounded. Nolan is subsequently captured and taken back to Viltrum to be executed, while Kregg, a high-ranking Viltrumite general, tasks Mark with finishing Nolan's original mission of preparing Earth for their invasion, or else they will destroy it. Meanwhile, Debbie accepts that her relationship with Nolan was a lie, stops accepting his income through Cecil, and throws out his books. Elsewhere, Donald discovers evidence of his own death. Suspicious that he might not be human, he stabs himself in the forearm as a test. Initially relieved to draw red blood, he then notices that he has bent the knife's tip.
