Ciara nods, "water will be important, yes. But if there is fresh water on the island, then it will have to run somewhere, and all rivers hit the ocean eventually. We shouldn't try and jump straight to deep penetration, but circle first. Get our bearings. I still think that we should stick to the coast. If we can find a river outlet, we'll find the things that need the fresh water to live, and thus likely, food. And for that, we'll need pointy sticks. And then fire to cook it. Like I said."
((Ciara is entirely ignoring the possibility that the rivers might run underground, and thus not actually be obvious at the coast, but we'll let her keep her fantasy about not having to brave the innards of the island a little longer.))
