"Princess? What princess?" you say, putting on a befuddled look."I knew nothing about a princess."
"Oh yes you did," the old woman grins evilly. "And if you admit it, then I might even help you."
"Help me? You hardly even know me, and I don't know whether or not I can trust you!" you say, before remembering you're meant to be clueless. "And anyway, what princess?"
The woman sighs exasperatedly. "Fine, then, if you don't want my help, don't have it." And she goes to close the slit.
