History Recap / Supergirl2015S1E7HumanForADay

** The scene with the looters told by Supergirl to stand down mirrors the same situation where ''ComicBook/TheNew52'' Superman foils a robbery in progress post-''Men of Tomorrow'' StoryArc, but without his powers after temporarily losing them.

* AdaptationalHeroism: Subverted in the case of Henshaw, because he is ''not'' Hank Henshaw (the villainous Cyborg Superman of the comics), but J'onn J'onzz, the Martian Manhunter, [[DeadPersonImpersonation assuming Hank's identity]].

** Subverted in how the episode seemed set to confirm Henshaw as a villain, but he turns out to be one of the most iconic heroes of the DC Universe.

** Even most comic book fan viewers were stunned that after all the buildup of Henshaw being the evil Cyborg Superman, it turned out he was really the Martian Manhunter instead.
** A minor example at the beginning of the episode, when Jemm threatens to expose Hank's true nature...as a coward.

* CavalryBetrayal: Subverted. Mind control is involved, and Hank sees through the deception in seconds.
* ChewingTheScenery: Henshaw lied about the neural disruptors being destroyed "because I didn't want you DOING SOMETHING STUPID LIKE THIS!!!"

* ConspiracyRedemption: The DEO's focus on extraterrestrial criminals, and its leader's seeming xenophobia, has placed it under some suspicion over whether it would eventually go after benign aliens like Supergirl and her cousin. It turns out that Henshaw's DEO was truly xenophobic, which is why when J'onn J'onzz took it over, he began to slowly reform it.

* TheEndingChangesEverything: For weeks, the show has been hinting that Hank has already became the Cyborg Superman and will inevitably go crazy like his comic book counterpart. As it turns out, Hank Henshaw died years ago, with J'onn J'onzz taking his place and no one the wiser. And unless the series intends to make major changes to the character, J'onn J'onzz is about as far from crazy as it's possible to get.

* {{Foreshadowing}}: When Jemm hisses to Henshaw that he will grind his loved ones to dust, a quiet Henshaw whispers "there are none left to grind."
* FreezeFrameBonus: During Henshaw's fight with Jemm, which is shot mostly in darkness, a few frames show that he is actually fighting in his full Martian Manhunter form.

* InternalReveal: J'onn reveals Alex that he was actually impersonating Hank to reform the D.E.O. and to protect her by a request from Jeremiah.

* NeckSnap: How Henshaw kills Jemm once and for all.

* RedShirt: The DEO agents who are not Henshaw or Alex. The two who go with Henshaw are killed within a minute of danger, and the third gets mind-controlled just after he and Alex reach where the first two died.

* SecretKeeper: Hank/J'onn tells Alex she's going to find out something only one other living person knows, and she can't even tell Kara.

'''Henshaw:''' I am the sole survivor of my planet. [[ComicBook/MartianManhunter The last son of Mars.]] ''(transforms into his full Martian Manhunter form)'' My name is J'onn J'onzz.

** Earlier, the amazing effect as Henshaw transforms into the full green-skinned J'onn in front of a stunned Alex.
* YouKilledMyFather: Alex believing this about Henshaw just makes things worse at a point when she has to be able to trust him.

* PlotHole: As seen in [[Recap/Supergirl2015S1E4HowDoesSheDoIt "How Does She Do It?"]], the DEO has a device that mimics the effects of Earth's yellow sun, which would allow them to recharge Kara's cells. No explanation is given as to why said device isn't used here (though from a meta standpoint, it's a NecessaryWeasel for the story to work).
