The second season begins with a series of surprising new dramatic events, where Eve suffers from the violence that has caused further abuse against Villanil. Now, Eve does not whether Villanelle is alive or dead where it seems very mysterious. On the other hand, Villanil, who was paranoid and seriously injured, managed to do good when she moved herself to the hospital for treatment before it was too late. On the other hand, Caroline is trying to get closer to the new Eve of the disorder by getting a new chance.
[Villanelle] lives for chaos and caprice, and what could be more unpredictable than someone who doesn't know what they're going to say or do until the second they do it, and even then has no idea why or what it means?
The writers aren't blinded by Villanelle in the way Eve has become. The stupidity of this operation is the actual point, rather than an accidental byproduct of pairing the two leads.
