Episode 4 of Season 2 of "Invincible" bridges the narrative gap by revealing Nolan's cosmic odyssey following his departure from Earth. Wandering aimlessly through the vast expanse of space, Nolan narrowly escapes being swallowed by a black hole but serendipitously rescues a group of Thraxans on the brink of a similar fate. He reappears before Mark, echoing the haunting scene from the preceding episode, much to Mark's mixed emotions—relief tempered by disappointment as Nolan reveals his sole purpose in returning is to aid the Thraxans. Nolan has forged a new life with Andressa (Rhea Seehorn), his wife, and their infant child.
Elsewhere, Debbie, barefoot and resilient, treks across the urban landscape to visit Nolan's mock tomb, a poignant gesture of her unresolved grief. Meanwhile, the Mauler, a burnt and scarred figure, spawns another clone, Donald, who—upon finding his glasses at the scene of his demise—stumbles upon unsettling truths about his existence. Nolan implores Mark to assist in shielding his new family from the menacing Viltrumites, whose arrival precedes Mark's decision-making. Eve squares off against Killcannon once more, amidst expectations that prove unfulfilled as Eve's actions inadvertently wreak havoc.
Andressa confides in Mark, her voice tinged with sincerity, that her life span equates to but a single human year, her intentions never to usurp anyone's place. As Mark confronts Lucan, a formidable Viltrimute warrior, Nolan intervenes, rescuing his son from certain peril. Eve's clash with Killcannon takes a turn for the worse, causing collateral damage that underscores the gravity of their conflict.
Art arrives at Debbie's doorstep, offering solace and empowering her to recognize her inherent strength.

Fuelled by a searing anger stemming from the loss of countless innocents, Mark taps into a reservoir of unprecedented speed and power. Just as victory seems within grasp, Lucan reappears, complicating the equation. The Viltrumites seize Lucan and Nolan, providing them with medical aid amidst the chaos.
