Culd Olivia be the alter ego of Viola?
Both female characters used a name with the same letters (diferent order though), both aren't trapped in anything but love (so they are smart and strong but can't do nothing against Cupido's arrows); both are trapped in a lie: Olivia is stuck in the main idealistic idea of love, so she loves to love; Viola is stuck playing like a man when she's a woman who would like to express her real love to Orsino and can't, what make them human, that is, touchable. Well, you will say.
