Clark looks at his son. At Lois. At the monster on the other side who is just a grieving father.
Lois realizes it first. "The pendant fragments. They're not weapons. They're phones . He's been calling you."
Lois grabs her coat. "That's not a portal. That's a lens ."
"Time to push him over."
Cut to space. BIZARRO SUPERMAN (the real one, not the zombie from earlier) is pushing through the dimensional barrier, bleeding red sun radiation, screaming Lois's name.
