Edge explains his origins to Superman as he enacts the final stage of his plan.

* AbsenteeActor: Wole Parks (Irons) sits this episode out.

* AmbiguousSituation: Jonathan wonders if the Morgan Edge from Irons' Earth was also Tal-Rho. And since that Earth's Kal-El didn't marry Lois or have any family, it was easier for Tal-Rho to persuade him to turn against humanity since he was offered the family he never had and was no longer alone. Jonathan worries this will happen to them since Clark is being offered his Kryptonian family back, but Lois shuts the fear down with how ''they're'' Clark's family on Earth-Prime and he will never abandon them for any reason.

* WillingChanneler: Lara explains that the Eradicator can't imprint a mind onto an unwilling host. Even if they don't understand the full context of what's happening to them, the subjects do have to consent to the procedure for it to work. This is why Edge recruited individuals willing to do anything to improve their lot in life.

He worries this will happen to them since Clark is being offered his Kryptonian family back, but Lois shuts the fear down with how ''they're'' Clark's family in this world and he will never abandon them for any reason.

* FreudianExcuse: When Edge landed in Britain as a child, he was shot at, captured and studied until he eventually escaped. Hence, this tragic experience fuels his hatred of humanity and to see them as the enemy or, at best, "inferior" to Kryptonians.

** Though related in vague terms, Lana's explanation of Tal being the result of a genetic match vs Kal being a birth suggests the latter's origin (and Kryptonian reproduction in general) is roughly similar to that of ''Film/ManOfSteel'' and ''Series/{{Krypton}}''.
** Tal-Rho being a Kryptonian who landed in Britain, nods slightly to ''ComicBook/SupermanTrueBrit'', if not also a Meta-gag to Superman's traditional Kryptonian enemy, General Zod, thrice being played in live-action[[note]]the Creator/ChristopherReeve films, ''Series/{{Smallville}}'', and ''Series/{{Krypton}}''[[/note]] by British actors.

* PutOnABus: Irons's absence continues in this episode.

** The device Morgan Edge has been using to implant Kryptonian consciousnesses in humans is called the Eradicator, an invention of Lara which also allowed Jor-El to preserve his consciousness in the Fortress. Edge is using it to colonize Earth.

** Jonathan tells Jordan about seeing the footage of alternate Superman killing alternate Lois.
