History Recap / ArrowS4E5Haunted

* WhatTheHellHero: Oliver is understandably furious at Laurel for bringing Sara back from the dead and keeping it secret from him since she's now killing people. To which Laurel gives him one on how she's always been LockedOutOfTheLoop regarding his own secrets and how he's never been that supportive of a friend, since he point-blank refused to support her when she wanted to take up the Canary mantle.

* FaceRevealingTurn: John Constantine in the flashback scenes, and Sara in the present (Oliver not having known that she was alive).
* {{Foreshadowing}}: Several for ''Series/LegendsOfTomorrow'' with the introduction of John Constantine, Ray Palmer turning out to be alive, and Sara wearing a white overcoat (and when her soul is pulled from the Lazarus Pit, a white negligee) foreshadowing her becoming the White Canary.

* BavarianFireDrill: How Quentin and Dig escape. Too bad Dig didn't know the plan before...

* {{Foreshadowing}}: When Oliver and Laurel pulls Sara's soul from the "pit", she's wearing a [[Series/LegendsOfTomorrow white]] negligee.

* IOweYouMyLife: In the flashback, Oliver saves Constantine from a non-magical spike trap. Constantine says he owes him a favor, which Oliver calls in during the present day plot.

* ChronicHeroSyndrome: After Flashback-Oliver saves his life, Constantine tells him he's a boat waiting to take him off Lian Yu. Oliver chooses to stay to help rescue the prisoners.

* BaitAndSwitch: Sara brutally but efficiently stops an AttemptedRape like in her Canary days, only to attack the victim as well.

* AntiHero: Constantine still is one. He's a snarky conman, but still "pure of heart".

* ChickMagnet: Given a LampshadeHanging. Constantine says that he'd have come to see Oliver sooner if he knew he were surrounded by so many beautiful women.

'''Season 4, Episode 5''':
!Haunted

* ContrivedCoincidence: Just as Conklin seems to have undeniable proof that Flashback!Oliver isn't telling the truth because of the communications kit, Reiter is busy interrogating John Constantine, who is an outsider infiltrating the island and providing a convenient scapegoat.

* GeniusLoci: Flashback!Constantine warned Flashback!Oliver that Lian Yu draws bad people to it.

* SarcasticConfession: Flashback!Oliver dismisses Conklin's accusation that he's a mole by saying he clearly must have parachuted in from a spy plane on a secret mission.
* SeenItAll: After four years of weirdness, Flashback!Oliver's not that surprised that magic exists. He doesn't even bat an eye when he learns that [[IslandOfMystery Lian Yu]] is literally a magical DoomMagnet either, probably because [[DoingInTheScientist that explains a lot of what he had to go through]].

Sara is on a rampage across the city attacking women who look like Thea before finally finding and trying to kill her. Oliver calls in [[Series/{{Constantine}} John Constantine]]--who he had met on Lian Yu and assisted in recovering a mystical artifact--to restore Sara's soul to her body. While assisting Quentin in a mission for Darhk, Diggle discovers his brother's records are being erased, and finds out the truth about Andy and why he was killed by HIVE. Felicity and Curtis discover Ray Palmer is still alive

* AffablyEvil: Damien Darhk continues to give sage advice on how to deal with the soulless Sara between his instructions to Captain Lance. Darhk is also courteous enough to bring information about Andy Diggle as a reward for completing a HIVE mission with efficiency.

* AntiHero: Constantine still is one. He's a snarky conman, but still "pure of heart."

* BrokenPedestal: Diggle finds out his brother had been into criminal activity and had been assassinated by HIVE to eliminate competition.
* {{Bizarrchitecture}}: The spot in TheUnderworld where Sara's soul is being kept prisoner takes the form of a facsimile of Nanda Parbat where [[MobileMaze intruders keep getting back to where they started]] for all eternity -- unless you have someone like Constantine who can navigate the place.

** Oliver having known about Constantine since the start of the series makes it pretty odd that he didn't call in that favor while he was dealing with Ra's al Ghul, or more to the point when he realized that Damien Darhk was a full blown sorcerer.

** Ironically Laurel's speech actually highlights her hypocrisy more than Oliver's. Her accusation that Oliver keeps secrets and doesn't treat her as an equal falls flat when she hid the fact she resurrected a souless Sara who is ''out on the streets killing people.'' With that, Oliver has a damn good reason not to trust her with anything. In the same speech she complains Oliver never thinks about how she feels, when Laurel's actions have put ''Oliver's'' sister in the hospital, while he's busting his gut to save Laurel's sister.

* {{Irony}}: [[Recap/ArrowS2E20SeeingRed Previously]], when Roy was on a Mirakuru-fueled rampage across the city, it was Sara who suggested [[ShootTheDog killing him to save everyone else]]. Now, Sara ''herself'' is on a similar type of rampage across the city, and her own sister ponders killing her to save everyone else. In both instances it's Oliver who (correctly) assumes that they can instead be restored to their former selves, and killing them isn't necessary.

* KarmaHoudini: Laurel raises Sara from the dead against Nyssa, Thea and Malcolm's warnings. Sara then goes on a blood rage, killing several criminals, attacking ''multiple innocent women'' and hospitalizing Thea, while Laurel hides it from the rest of Team Arrow and on Oliver finding out - only yells that he's not thinking about ''her'' feelings. The result? ''Oliver'' calls in a favour to save Sara, Laurel gets her sister back and Oliver affirms her as his friend and equal.

* RealityEnsues: While running from Sara, Thea tries jumping a bannister to get down stairs faster by avoiding a landing. She ends up landing badly due to trying so soon after being choked, and falls down to the next landing.

* TheReveal: Baron Reiter isn't on the island only to make drugs, he's hunting supernatural artifacts as well.

* SexySoakedShirt: Sara 's soul is dipped in a Lazarus Pit-like tub and is wearing a negligee when Oliver and Laurel pulls her out.

* UnexpectedCharacter: Constantine, especially this particular version (from a cancelled show on another network.)

* AffablyEvil: for Damien Darhk continues to give sage advice on how to deal with the soulless Sara between his instructions to Captain Lance. Darhk is also courteous enough to bring information about Andy Diggle as a reward for completing a HIVE mission with efficiency.

* ActionizedSequel: To ''Series/{{Constantine}}'', since John wasn't much of a fighter on the show. He could throw one solid punch, but in combat wasn't skilled. Here, he can at least hold off a swordsman (albeit during a probable out-of-body experience, outside the physical plane).

* KarmaHoudini: Laurel raises Sara from the dead against Nyssa, Thea and Malcolm's warnings. Sara then goes on a blood rage, killing several criminals, attacking ''multiple innocent women'' and hospitalizing Thea, while Laurel hides it from the rest of Team Arrow and on Oliver finding out - only yells that he's not thinking about ''her'' feelings. The result? ''Oliver'' calls in a favour and risks his life to save Sara, Laurel gets her sister back and Oliver affirms her as his friend and equal.

* KarmaHoundi: Laurel raises Sara from the dead against Nyssa, Thea and Malcolm's warnings. Sara then goes on a blood rage, killing several criminals, attacking ''multiple innocent women'' and hospitalizing Thea, while Laurel hides it from the rest of Team Arrow and on Oliver finding out - only yells that he's not thinking about ''her'' feelings. The result? ''Oliver'' calls in a favour and risks his life to save Sara, Laurel gets her sister back and Oliver affirms her as his friend and equal.

* AwesomeButTemporary: Matt Ryan's guest spot as John Constantine is seen by many as the highlight of the episode (and is largely its entire point), which the producers have repeatedly described as a "one-off".

* TakeThat: Constantine gets in a subtle dig at NBC, the channel that mishandled and ultimately canceled his show, when he scratches his back with a dead peacock feather. The peacock, of course, is the mascot of NBC.

** Oliver having known about Constantine since the start of the series makes it pretty odd that he didn't call in that favor while he was dealing with Ra's al Ghul, or more to the point when he realized for Damien Darhk was a full blown sorcerer.
