* BadLiar: Simmons, [[RunningGag yet again]]. She tries to deceive Audrey into thinking they're from the CIA. Audrey easily figures out they're from S.H.I.E.L.D., but she doesn't mind since since S.H.I.E.L.D. saved her the last time Marcus showed up.\

* ButNowIMustGo: May decides that with Coulson's trust in her destroyed she doesn't belong on the team anymore, so she heads off on her own to find Maria Hill.

* SarcasticConfession: While under the lie detector, Ward says he's with HYDRA after Koenig gets suspicious, but Koenig ignores it since he follows up by saying that HYDRA had taken over so much of S.H.I.E.L.D. that ''every'' S.H.I.E.L.D. agent was complicit in HYDRA's activities whether they knew it or not.

* WhamEpisode: May leaves the team, Ward kills Agent Koenig, and Skye pieces together that Ward is a HYDRA agent.

* ChekhovsGun: Set up but not fired. There's a lingering shot of Skye looking at one of the "windows" which change images occasionally just before she allows Ward to find her.

** SarcasticConfession: While under the lie detector, Ward says he's with HYDRA after Koenig gets suspicious, but Koenig ignores it since he follows up by saying that HYDRA had taken over so much of S.H.I.E.L.D. that ''every'' S.H.I.E.L.D. agent was complicit in HYDRA's activities whether they knew it or not.

* MetaphoricallyTrue: Ward passes an enhanced polygraph test that ''Romanov'' was allegedly unable to beat by giving answers that were technically true but out of context.
** SarcasticConfession: He actually does say he's with HYDRA after Koenig gets suspicious, but Koenig ignores it.

* OhCrap: Ward has a bit of trouble hiding his apprehension when told that Fury's custom lie detector chair was designed to beat Romanov.

* ContinuityNod: Part of Koenig's test involves the subject's knowledge of Project Insight and Alexander Pierce, two major parts of ''Film/CaptainAmericaAndTheWinterSoldier''.

* BadLiar: Simmons, [[RunningGag yet again]]. She tries to deceive Audrey into thinking they're from the CIA. Audrey easily figures out they're from S.H.I.E.L.D., though fortunately, she's supportive of S.H.I.E.L.D.
* CannotSpitItOut: Fitz just can't bring himself to admit his increasingly obvious feelings for Simmons, even when Ward urges him to, Coulson subtly sets things up for him to do so, and Simmons is noticing his jealous hostility towards Triplett.
* CastingAShadow: Blackout gained this ability while in the Fridge—with S.H.I.E.L.D.'s help.

* DoubleMeaningTitle: In the past, Marcus Daniels had called Audrey "[[TitleDrop his only light in the darkness]]". It becomes a LiteralMetaphor when it's taken into account that Daniels can absorb all light into himself. The title may also refer to Ward finally showing his true colours ''around the good guys'' and Skye discovering this, alluding to HYDRA's message [[Recap/AgentsOfSHIELDS1E17TurnTurnTurn two episodes earlier:]] Out of the Darkness, Into the Light: HYDRA.

* RetiredBadass: Implied with May's Mom.
--->'''May's Mom:''' I may be retired, but I still have contacts. And ''my'' agency hasn't fallen apart.
* ShoutOut: Agent Koenig, as part of a polygraph test, asks each Agent, given the scenario that they're trapped alone on a desert island with a box, what they would find in the box. Simmons' answer? [[Series/DoctorWho The [=TARDIS=]]].

* TouchOfDeath: Another one of Blackout's abilities—he simply absorbs the electrical impulses powering the heart and brain.

* WeakenedByTheLight: How Blackout was taken out in the past and present, though the light had to be amped significantly up in the present.

* IdiotBall: Given how DangerouslyGenreSavvy Ward is, it's somewhat surprising that he didn't account for the possibility of Skye stumbling upon Koenig's body.

* StalkerWithACrush: Blackout's obsessed with Aubrey, who he considers to be his "light in the darkness".

* WhamEpisode: May leaves the team, Ward kills Agent Koenig, and Skye pieces together that Ward is a HYDRA agent.

* InternalReveal: Skye discovers that Ward is TheMole.

Things get personal for Agent Coulson, who must race against time to save his one true love, the cello-playing Audrey (Amy Acker).

* CharacterDeath: Agent Koenig.

* StalkerWithACrush: Blackout, big time.
