The second season of Invincible ended things with Mark killing Angstrom, or at least one of the versions of Angstrom, after he broke Debbie’s hand, harmed Oliver, and sent Mark through an endless list of parallel realities. Mark was rescued by an alternate version of the Guardians of the Globe and sent back to his reality, but before parting ways, the alt-Atom Eve advised Mark to give the Eve from his world some form of closure, romantically speaking, so as to save her from a life of misery. After returning home and telling Debbie that he was going to fully focus on being a superhero, Mark did meet up with Eve with the intention of speaking from his heart. However, he refrained from doing so because he was too shaken to converse coherently. In addition to that, it was revealed that Dupli-Kate was alive and planning to live with Immortal.
