I'm still happy with the punchline, a fun gag at the expense of both characters. Eve can't leave the house until she has her biases confirmed, and any scrap of validation will do. Even Hanna expressing that she won't "be mad" if Eve goes and does it is enough. If this is the only deterrence, who could possibly stop her in a loving way? The truth is that Eve DOES need to scratch it out - it's an itch she's been suffering for too long - and support (for the aftermath) is the only thing her friends have a prayer of communicating. This is just too oppressive for Hanna to bear, even though not holding her friend hostage "for her own good" is remarkable growth on her part.
