History Recap / BlackLightning2018S3E9EarthCrisis

* KickTheSonOfABitch: Jinn being erased by the Anti-Matter wave could be considered this. [[spoiler: It's unclear whether or not her Earth was even restored when [[Recap/ArrowS8E8CrisisOnInfiniteEarthsHourFour Oliver rebirth the Multiverse]].]]

* ContinuitySnarl: The episode sets up “Earth One” and “Earth Two” versions of Jennifer, who aren't likely to be the same worlds that the other Arrowverse shows refer to by those designations (For starters, Earth-2 was erased at the end of “[[Recap/ArrowS8E1StarlingCity Starling City]]”). It's likely this was intentional, as the whole point of the episode was to show a GoodAngelBadAngel situation, more than setting up their multiverse placement (even Black Lightning's Earth is denied a designation; the Arrowverse wiki calls it Earth-BL for the sake of covering it).
* CrossThrough: In the grand scheme of Crisis, Black Lightning's Earth was just one of many in the process of getting erased, with Jefferson escaping the Anti-Monitor Wave to take part in the [[Series/CrisisOnInfiniteEarths2019 Crossover]].

* GenreShift: For at least this episode, Black Lightning was allowed to have elements more commonly found on [[Series/TheFlash2014 The Flash]] and [[Series/Supergirl2015 Supergirl]].

* OmnidisciplinaryScientist: Gambi's TechnoBabble has him theorise from a fairly short examination of Jennifer's condition that she may be phasing uncontrollably into other dimensions (which the others scoff at initially), and explains that the red skies are interfering with her powers, and the skies are giving off anti-matter. How he has a machine to detect this is a bit baffling, and because of this, he figures out the multiverse faster than even the world's greatest geniuses on the Arrowverse's Earth-1 were able to. Justified to some extent, as we do need a MrExposition for TheMultiverse concept just so Jefferson doesn't go into the Crisis totally unprepared. In-universe WildMassGuessing ensues that the ASA is involved in changing the skies, or being in even more branches of clandestine super-science that the cast were previously unaware of, of which Gambi shoots down as, being a former ASA Agent, he knows what the ASA does, and weather manipulation isn't one of those things.

* SpellMyNameWithAnS: The alternate versions of Jennifer are differentiated from her by the spelling of their names: her Earth One counterpart is "Gen" and her Earth Two counterpart is "Jinn". The former seems like she may just be named "Gennifer" rather than "Jennifer"; the latter, judging by the rage she exhibits when her father calls her "Jennifer", picked "Jinn" as a supervillain alias (see MeaningfulName).

* KickTheSonOfABitch: Jinn being erased by the Anti-Matter wave could be seen as this. [[spoiler: And it's unclear whether or not her Earth was restored when [[Recap/ArrowS8E8CrisisOnInfiniteEarthsHourFour Oliver recreated the Multiverse]].]]
