** [[spoiler:Jack covered up Siri's escape to save his job, including later destroying that showed Helena is not her.]]

* AdultFear: Helena finds herself locked in a secure mental institution where everyone believes that she's her dangerous twin.

* CassandraTruth: No one believes Helena is who she says, instead of her twin Siri. Those who do entertain it don't for long, since things always point the other way. [[spoiler:Until the last few episodes, but then those with interests in doing so cover it up.]]

* MixedAncestry: Helena mentions having an American mother and Swedish father (along with her twin Siri).

* CassandraTruth: No one believes Helena is who she says, instead of her twin Siri. Those who do entertain it don't for long, since things always point the other way. [[spoiler:Until the last few episodes, but then those with interests in doing so cover it up.]]

* WoundedGazelleGambit: Dr. Fisher injures himself, then tazes Margot, making it look as though she'd done this because she'd reveal Helena isn't Siri otherwise, to discredit her as this could ruin his career.

* CassandraTruth: No one believes Helena is who she says, instead of her twin Siri. Those who do entertain it don't for long, since things always point the other way. [[spoiler:Until the last few episodes, but then those with interests in doing so cover it up.]]

* YouHaveToBelieveMe: Helena tries all that she can to convince people she's not Siri. She goes about it more calmly and logically than most, but since Siri is a sociopath, they're suspicious, because lying to manipulate is very common for this condition. Helena attempts to show evidence she isn't Siri, but it always falls apart.

Helena attempts to show evidence she isn't Siri, but it always falls apart.

* LackOfEmpathy: The defining trait of sociopathy, which the sanitorium's psychiatrists exposit about. Helena having empathy is a sign to them of Siri improving, surprisingly.

* InsecuritySystem: Despite them boasting that their security system is airtight, the sanitorium staff apparently saw no issue with leaving identical twin sisters together, such that one of them could walk out impersonating the other.

* EvilDetectingDog: Luck, a dog at the sanitorium, barks at Siri but likes Helena. Siri, it turns out, is a dangerous sociopath, quite unlike Helena. Luck also dislikes Raymond, another dangerous sociopath.

* GreatEscape: There are rumors throughout the series of patients planning an escape, but it turns out to be largely false. [[spoiler:In the season one finale Helena and Enzo manage it, despite extensive security measures.]]

* ActionGirl: Helena and Siri were both pushed to learn self-defense skills by their father, rather than traditional feminine things such as ballet. So they learned aikido instead. It serves Helena in good stead at the sanitorium.

* {{Blackmail}}: Carol gets ahold of the hammer Siri used to beat another woman into a coma, and uses it as leverage on Helena, her twin, since as they're identical DNA evidence Siri left would also implicate her.

* DirtyCop: Some of the "hosts" (guards/orderlies) are in bed with Carol, a ruthless crime boss among the patients, who cover up his dealings.

* ObfuscatingInsanity: Enzo faked having sociopathy, thinking he'd get better treatment in a mental institution vs. prison. This ended up [[GoneHorriblyWrong backfiring however]], as now he may never leave, and every attempt to prove he's not a sociopath has been taken as sociopathic manipulation.

* ShowerScene: Helena is shown going into the showed topless in episode three.

* YouHaveToBelieveMe: Helena tries all that she can to convince people she's not Siri. She goes about it more calmly and logically than most, but since Siri is a sociopath, they're suspicious, since lying or manipulating others are common traits.

* EvilDetectingDog: There's a dog at the sanitorium who barked at Siri, but likes Helena. Siri, it turns out, is a dangerous sociopath, quite unlike Helena.

Helena visits her estranged twin sister, Siri, in a sanatorium within the Italian Alps where she resides. After claiming she's there to get help with alcohol and drug problems, Siri begs Helena to switch places with her so she go visit her girlfriend on the outside, who's been badly injured by her ex-husband. Helena refuses, then finds the next day that she's been drugged by Siri, who left in her clothes anyway. Though Siri had proposed only being gone a day, she never returns. After this, Helena is horrified to realize that everyone, staff and patients, believe she's Siri. Not only that, but the sanitorium and Siri herself have far darker things going on than Helena realized...
