History Recap / Supergirl2015S3E8CrisisOnEarthXPart1

** Barry asks Kara to sing at his wedding, having noted her impressive soprano [[Recap/TheFlash2014S3E17Duet the last time they met]].

** The awkward waitress at the wedding reception[[note]]heavily implied to be Barry and Iris’ future daughter Dawn Allen, or Dawn's future daughter Jenni Ognats[[/note]] says she’s just really happy to be there. At a wedding, any wedding. Not specifically Barry and Iris’, of course.

* WhamShot: Dark Arrow and Overgirl are Oliver and Kara's doppelgangers, respectively. And Eobard Thawne is still alive and once again wearing Harrison Wells' face.

'''Barry:''' [[SubvertedTrope ...oh. That's... I got nothing for that, I'm sorry.]]

** When she shows up nearly late to the wedding, Alex claims she was out "jogging... fully clothed." Then Sara arrives and foregoes any pretense about the fact that she and Alex had sex.

* TooDumbToLive: Not a single one of the Resistance soldiers Dark Arrow attacks at the beginning thinks of just firing their weapon at him instead of charging towards him, which naturally gets them all killed. Of course, [[StatusQuoIsGod this is generally the case with Mooks... they never shoot at the main characters.]]

* SanDimasTime: While in 1183 AD England, Sara abruptly remembers that the Legends never [=RSVP=]ed for Barry's wedding.

** 1183 AD Nottingham, the Legends are robbing a bunch of royal tax collectors.

It is the day before Barry Allen and Iris West's WeddingDay, and some "special guests" show up to make this a momentous occasion. In the ceremony itself, before they can exchange their vows, some uninvited guests arrive: Nazis, from the "secret" world that is Earth-X.

The heroes of Earth-1 (and Supergirl) must contend with an invasion by a hostile world in the multiverse.

* BreatherEpisode: Outside of the cold open and the disruption of the wedding, this episode doesn't really concern itself that much with the Earth-X plot.

* SanDimasTime: While in 1183 AD England, Sara abruptly remembers that the Legends never [=RSVP=]ed for Barry's wedding. Justified, since [[MundaneUtility using the Waverider to RSVP on time]] would require them to travel to a point in time where they already exist, which they know can have nasty consequences.

* DisintegratorRay: Overgirl's heat vision acts as this when she kills the wedding pastor.

** 1138 AD Nottingham, the Legends are robbing a bunch of royal tax collectors.

* ArrowsOnFire: Sara catches one in 1138 AD England when noting that the Legends are not Robin Hood.

* KissingUnderTheInfluence: Alex and Sara are first seen kissing after getting drunk. [[BedmateRevealThen we learn that they had sex.]]

* KissingUnderTheInfluence: Alex and Sara have sex after getting drunk.

** Cisco and Harry devise a serum to decouple Stein from the Firestorm matrix using [[AppliedPhlebotinum quarks]], [[Recap/TheFlash2014S4E1TheFlashReborn again]].

* ChainPain: Sara brought some kind of ball-and-chain variant to the wedding, which she uses against Prometheus-X.
** It is more likely that Sara just picked up a censer, which when in use would have had burning incense inside.

* {{Crossdresser}}: While staying at Stein's house, Rory borrows a flowery nightrobe from Stein's daughter since she objected to him walking around the house naked. Played With, as the terminology he uses seems to indicate he’s just wearing one of Martin’s bathrobes that he is ''calling'' a dress.

** Killer Forst hates pink - guess what Caitlin is wearing at the wedding?

* FunnyBackgroundEvent: Mick spends the entire wedding procession catching some Z's and no one bothers to wake him up.

* NoodleIncident: It isn't explained in the ActionPrologue how King Shark broke out of A.R.G.U.S. custody.

* NothingUpMySleeve: At the wedding, Oliver keeps a bow that’s collapsible to the size of a small baton up his sleeve, [[CrazyPrepared just in case]].

--> '''Kara:''' The end of the world.
--> '''Barry:''' Faced that three times.
--> '''Kara:''' Time travel.
--> '''Barry:''' I've been there a lot.
--> '''Kara:''' He's married to someone else.
--> '''Barry:''' [[SubvertedTrope ...oh. That's...I got nothing for that, I'm sorry.]]
