Right and if there's also restrictions that stops her for telling them she can't answer them directly then she can use ways like a puzzle that they'll need to answer and give them some clues. Like when someone ask us if they look pretty but we don't want to offend them so we use other words to answer them.

She should have use words or stories that only Gabriella knows to tell them shes Gabriella without telling them that shes really Gabriella. Just clues that will give them hint. And when he ask her if she's Gabriella she should have use other ways to use as confirmation.
