History Recap / Supergirl2015S1E4HowDoesSheDoIt

* BombDisposal: Comes up twice in this episode. The first time there's a bit of WireDilemma and WrongWire when Lord cuts a wire, believing it will defuse the bomb, only for the timer to start going faster, forcing Kara to desperately fly the bomb a safe distance away from the city before it detonates. (Of course, Lord cut the wrong wire on purpose to test Supergirl's speed and durability.) The second time, Henshaw manages to defuse the bomb with the help of his as-yet-unexplained powers, later claiming the bomb was a dud.

* ShesGotLegs: When Cat asks Carter what he thinks makes Supergirl a hero, this is his first answer, before [[{{Troll}} laughing it off]] and saying it's actually Supergirl's heart that makes her a hero.

* ShesGotLegs: When Cat asks Carter what he thinks makes Supergirl a hero, this is his first answer, before [[{{Troll}} having a laugh at his mother's expense]] and saying it's actually Supergirl's heart that makes her a hero.

* OutOfOrder: Aired fifth in the season despite being fourth, due to the [[TooSoon attack on Paris]] the previous week. This episode suffers quite a bit more from the switch:

* CuttingTheKnot: When Alex asks Kara to hand her an allen key in order to remove the end of a disabled bomb, Kara simply pops the end off.

* OutOfOrder: Aired fifth in the season despite being fourth, due to the attack on Paris the previous week. This episode suffers quite a bit more from the switch:

* TooSoon: The episode was postponed due to the 2015 Paris attacks.

!!Tropes in this episode include:

* YouOweMe: Cat mistakenly assumes this is why Kara agreed to watch Carter, but rather being upset by it, she actually admires this (perceived) quality in Kara.

* GambitRoulette: While the bomb at the airport is reported in, Kara initially doesn't find any on the train or station, and Knox doesn't make any announcement he is carrying a bomb. Lord's SadisticChoice depends on the two bombs being revealed almost simultaneously, and it's only dumb luck that Wynn recognizes Knox and contacts Kara, before she arrives at the airport to deal with that device before anyone knows about the bomb on the train. Also, Lord is only able to guess that Kara knew someone on the train because he invited Carter (who, at the time, he only knew as some random kid with no connection to Supergirl) on the train and Kara found out about it.

* WouldHurtAChild: Lord shows no hesitation in inviting Carter onto the train, knowing fully well it's going to be bombed. It can't even be part of his plan, either, since A) he doesn't know that Supergirl knows Carter and B) he has no guarantee that she will find out.
** Though there’s a bit of OmniscientMoralityLicense, since he can disarm it whenever he wants.

* ParentsAsPeople: Eliza confessed that she and Jeremiah didn't know how to deal with raising a teenage alien girl with powers. Which is why they charged Alex with watching over her.

* KickTheDog: Maxwell Lord invites a young boy onto a train which he knows full well is going to be blown up. While this ultimately works out to his benefit (by giving him a clue to Supergirl's identity), he had no way of knowing that it would at the time, so this is basically just him being an evil son of a bitch.

* VillainWithGoodPublicity: Lord firmly moves to this.

* OutOfOrder: Aired fifth in the season despite being fourth, due to the attack on Paris the previous week. This episode suffers quite a bit more from the switch, with Cat asking about Kara's mother, and Kara shrugging off a glimpse of Henshaw's red eyes, as she wasn't supposed to be suspecting him of anything yet.
