History Recap / RickAndMortyS4E7Promortyus

** When Rick and Morty arrive back at the facehuggers' planet to retrieve Summer, they initially plan to infiltrate stealthily by using the same disguise as before of reattaching the parasites to their faces and pretending to be possessed by them...only for the aliens to recognize their ship--which they used to blow up most of the planet while they were escaping the first time--and confront them as "the worst thing to ever happen us" the instant they land.

* BigSisterInstict: Summer helping the facehuggers develop their society is in large part so they won't just kill Morty and Rick after 30 minutes by forcing them to defecate eggs the way they usually do with their hosts. Later, Summer directly and seriously tells Steve, the parasite possessing Morty, that he needs to give her brother back.

** When Rick and Morty return to the facehuggers' planet, they initially try to pretend to be possessed again by putting the aliens back over their faces; however, since they once again fly in on Rick's ship, which they earlier used to destroy most of the planet, the aliens immediately recognize them as "the worst thing to ever happen to us" and attack them, which Rick admits makes sense.
** Rick's "unnecessarily badass" suits for himself and Morty include a {{BFS}} for each of them. Since neither of them has had the proper training with sword fighting, we hear both of them complaining after just a few minutes about how much swinging the swords hurts their wrists. Rick decides to go with flamethrowers next time, and when Morty asks if he can have a [[WhipItGood laser whip]], Rick notes that he'd definitely cut his dick off by accident with it.

* WritersCannotDoMath: See ArtisticLicenceBiology above.

* ArtisticLicenceBiology: The parasites have one child and then die so they'd never be able to increase their numbers. Some would inevitably get killed befor they had a chance to breed, meaning their numbers would gradually decline.

* {{Hypocrite}}: The aliens are basically doing what Unity was doing, except they have an actual society and individuals instead of just one hive-mind. This time, however, Rick, Morty, and Summer just see them as evil and kill them without second thoughts, though the facehuggers do at least call them out at the end for having flimsy reasons to consider them "evil".

* TheStinger: Summer's friend Tricia Lang observes Jerry's beekeeping in the backyard and repeatedly makes somewhat-awkward comments about it, while Summer mostly ignores her and plays on her phone. And then...
-->'''Tricia:''' ...Summer, I wanna fuck your dad.
-->'''Summer:''' [[SarcasmMode Oh really?!]]

* StartsStealthilyEndsLoudly: When Rick and Morty return to Glorzo, they try to stay undercover but after a few steps out of their shuttle they are already surrounded by some Glorzos which prompts Rick to engage plan B which means fighting their way through.

** Quickly after, Rick tells Morty that he shouldn't worry about putting the facehugger back in this face because it's dead. Cue the little sucker reviving and trying to attach itself to Morty.
* InternalDeconstruction: This episode examines the aftermath of Rick and Morty's adventures, showcasing the sheer damage they do and how it affects the aliens. This episode shows how the duo's adventure amounted to a massive genocide and terrorist attack. One even refers to Rick and Morty as the worst thing to ever happen to their species and Rick explicitly mentions it as the reason they never head back to worlds they've been to before.

* {{Hypocrite}}: The aliens are basically doing what Unity was doing, except they have an actual society and individuals instead of just one hive-mind. This time, however, they are evil and killed without second thoughts.

* GreenEyedMonster: Rick's parasite became counterculture and preached for the parasites to go back to crapping eggs because he was jealous that Summer was taking Morty's parasite away from him.

* CreatorProvincialism: Rick and Morty referring to the damage they caused to the alien city in terms of American history. While it's understandable for the twin towers, the fact that they see the bombing right after as a parallel to Pearl Harbor instead of other instances when the american navy was the bomber is this trope.

* CringeComedy: Bruce and Steve are two facehuggers who are deeply in love, and at one point begin making out, stroking each others' faces, and holding hands--or rather, their hosts' hands. Where it gets cringe-y is that said hosts are, respectively, Rick and Morty, a [[IncestSubtext grandfather]] [[{{Squick}} and]] [[NoYay grandson]] pair.

* ConversationCut: At the dinner table, Morty tells his mother that Summer is sleeping. Cut to him and Rick in the shuttle where Rick scolds Morty four using "sleeping" as an excuse.
