After a little ways into blank woods with only the maps confounding riddles to aid him further, Jack stops and turns to Anaba.
"D'you want t'know what 'm looking for?" Perhaps she's at least heard legends. He tries to word it better for her. "Anaba. Want to know what Jack hunts?" It's the closest equivalent he can manage.
He unrolls the map that he's been carrying with him. His own hand drawn version is wrapped up inside. He points to the illustrated 'Aqua de Vida'. "Life water."
