History Recap / ArrowS4E21MonumentPoint

* KickTheSonOfABitch: Although Machin is far worse than her, it's hard to feel bad when he brutally stabs [[AssholeVictim Ruve Adams]] to death.

* ArtificialOutdoorsDisplay: Tevat Noah was designed by H.I.V.E. to mimic a suburban town, with the algae from Star City Bay providing oxygen to the entire facility. The facility is the only place on Earth safe from Damien Darhk's planned apocalypse.

* IncrediblyLamePun: Anarky tells Thea she's not a pawn--she's a queen.
-->'''Anarky:''' ...Get it?\\
'''Thea Queen:''' [[SarcasmMode Yeah, I get it.]]

* DownerEnding: Although Team Arrow manages to stop most of the deaths Genesis could have caused, they do so at the cost of destroying a major city, leaving thousands of innocence dead. Furthermore Damien Darhk only needed to destroy that one city in order to [[TheBadGuyWins become all powerful.]]

* LeaningOnTheFourthWall: Felicity refers to Murmur and Brick -- a Season 3 VillainOfTheWeek and mid-season ArcVillain, respectively-- as "last year's specials."

* CorruptCorporateExecutive: Subverted with the Palmer Tech board of directors. They dislike Felicity's charitable use of company resources, but they actually want to have a proper board meeting to discuss this with her. [[RealityEnsues Only after Felicity keeps making decisions of her own without bothering to contact the board do they throw her out, which is a perfectly valid reason in real-life.]]

* RealityEnsues: Just like Oliver before her, Felicity's neglect of her duties as CEO during a crisis leads her to being terminated.

* ArtificialOutdoorsDisplay: Tevat Noah was designed by H.I.V.E. to mimic a suburban town, with the algae from Star City Bay providing oxygen to the entire facility.

** There's also Thea for 'creating' Anarky, and Oliver for setting him free from prison, resulting in the death of Thea's boyfriend.

* TooDumbToLive: Alex doesn't run away, leading to him being killed by Anarky.
** Too be fair, he was under H.I.V.E.'s mind control. There's little telling what was going through his head.

* DeathBySecretIdentity: Alex watches dumbfounded as his girlfriend spars with Anarky, right before he's killed by Anarky. Anarky also discovered Speedy's SecretIdentity in this episode, but killing Thea's boyfriend won't help his life expectancy either.

As Team Arrow scrambles to stop Hive from destroying the world, they form a tenuous alliance with Felicity's father, the Calculator. Meanwhile, Thea has to stop Anarky from blowing up Hive's bubble.
