History Recap / ArrowS2E6KeepYourEnemiesCloser

* SuperSerum: What Ivo's looking for; the Imperial Japanese apparently did research into stem cell research during UsefulNotes/WW2 but lost the prototype formula when the Allies attacked the submarine transporting the only supply. The submarine ran aground somewhere in the chain of islands that includes Lian-Yu, and Ivo is looking for the graves of the sailors killed in the attack to pinpoint which island it was.

* DefrostingIceQueen: Zigzagged; when [[ButLiquorIsQuicker she has a few vodkas in her]] Isabel shows a more relaxed side to herself, who sees through Oliver's rich idiot façade and realises they are NotSoDifferent. They end up in bed together, but she reverts to her IceQueen persona when Oliver is NotStayingForBreakfast and apparently going off with Felicity. The next day she appears to be on friendly terms, but shuts down Oliver's attempt to discuss What Happened Last Night.

* AmbiguousSituation: Is Sara merely Ivo's minion or [[AMatchMadeInStockholm is she his mistress]] as well? The Captain drops a snide comment implying that she's sleeping with him, but even though Sara's [[ReallyGetsAround loose sexual morals]] will become a RunningGag in [[Series/LegendsOfTomorrow later years]], it's not confirmed either way.

* WeDoNotKnowEachOther: Subverted; Sara invokes this trope with 'Tommy', but it turns out Ivo knows exactly who she is and Sara is working with him to get information on Oliver's friends.

* AmbiguousSituation: Is Sara merely Ivo's minion or [[AMatchMadeInStockholm is she his mistress]] as well? The Captain drops a snide comment implying that she's sleeping with him, but even though Sara's [[ReallyGetsAround loose sexual morals]] will become a RunningGag in later years, it's not confirmed either way.

* IShallReturn: When Sara lets Oliver out of the cell, he promises Anatoli that he will come back for him.

* ComplexityAddiction: Instead of just calling Diggle on the phone, ARGUS abduct him after one of Team Arrow's vigilante escapades. When Diggle complains that he though ARGUS was more subtle than that, Waller replies that this ''is'' them being subtle. On the other hand this does make it clear they know all about what he and Oliver are up to, avoiding wasting time with denials.

* WhamLine: Mostly for WorldBuilding effect, but this bit when Deadshot tells Diggle he was hired to kill his brother.
-->'''Diggle''': Who would want to kill Andy?
-->'''Deadshot''': I don't know their name, just their alias -- [[NebulousEvilOrganization H.I.V.E]].

-->'''Ivo:''' You're going back to the island...Oliver.

* WhatMeasureIsAMook: Despite their "no kill" rule back in the States, Team Arrow have no problem shooting or blowing up several prison guards.

* SuperSerum: The Mirakuru serum enables SuperStrength and [[HealingFactor cell regeneration]].
* SuperSoldier: What Ivo's looking for; the Imperial Japanese apparently did research into stem cell research during UsefulNotes/WW2 but lost the prototype formula when the Allies attacked the submarine transporting the only supply. The submarine ran aground somewhere in the chain of islands that includes Lian-Yu, and Ivo is looking for the graves of the sailors killed in the attack to pinpoint which island it was.

** Felicity has to interrupt the argument between Oliver and Isabel because of his 'evening plans' with Harper. Given that she looks [[NotWhatItLooksLike exactly like she's discussing a date]], Oliver gripes that she needs to work on her excuses.

** Ivo asks Oliver if he's seen a [=WW2=] Japanese submarine while he's been on the island.

** The ARGUS men who abduct Diggle use the callsign Task Force X.

* DefrostingIceQueen: Zigzagged; when [[ButLiquorIsQuicker she has a few vodkas in her]] Isabel shows a more relaxed side to herself, who sees through Oliver's rich idiot façade and realises they are NotSoDifferent. They end up in bed together, but she reverts to her IceQueen persona when Oliver is NotStayingForBreakfast and apparently going off with Felicity. The next day she, albeit with a friendly smile, shuts down Oliver's attempt to discuss What Happened Last Night.

* RogueAgent: Lyla was after Deadshot for Diggle's sake when she was captured. Waller still wants her back, but as there would be problems if ARGUS was involved with springing a prisoner of the Russian government, she has no issue with getting Diggle and his vigilante friends to do her dirty work.
