Perhaps the extreme behavior of the two Swedish sisters who crashed on the M6 was temporary, but given that drugs aren’t part of the equation, it seems more likely that this behavior is related to something more hidden (in our opinion, at least) and more durable . The “folie à deux” (induced paranoia) makes sense, but is it just a temporary non-drug delirium?
What about the family background of these two women? They choose to live away from home as adults. Why did you choose to do this? Just adventurers, or they feel they have to escape from something (including each other). Having similar experiences growing up as twins would have prepared them more for folie à deux (a common psychosis). Because even when not mentally ill, family members often affect each other mentally.
What about their pockets? Paranoia seems to be addressed there. Maybe their actions lead to some kind of temporary insanity, but that’s probably just because the madman (or madwoman) woke up, not because it was fabricated in an instant. The level of detachment/over-connection with Ursula that Sabina exhibits seems to be two sides of the same coin. It just isn’t grounded in reality on any level. She needs to be friendly and organized while also dealing with intimacy issues. That foundation may not have been established when she and Ursula were young children. Maybe they developed massive denial systems that worked for them in many ways (like it did for Sabina in the prison scene).
After her release from prison, Sabina greeted complete strangers on the street – brazenly – and went out with them. Maybe it’s her little way of saying, “I can take risks without really getting into trouble, so I’m in control even when it might get out of hand.” Just a thought. She handed them cigarettes and snatched them away. “They’re poisoned.” Is this just a paranoid thought? Or was it a symptom of a deep inner fear she suddenly couldn’t directly access or ignore? Maybe she’s torn between helping others to gain positive attention and being afraid to poison them. It just seemed like her way of withdrawing the offer, which made her suddenly very uncomfortable. She’s overly friendly on one level, paranoid and withdrawn on another.
She really wants to be helped, but trusts that the same knife that cuts her sandwich will cut her too. Maybe that’s why she thinks she needs to stab a stranger in the chest. There is almost always something more behind it, especially in the case of mental health issues. The mind is a black box full of history and mystery.
