Leave her be and backtrack to the cavern with the pool.

You are afraid of this stranger - and for good reason, considering the last interaction you had with anyone was them trying to hurt you. You immediately backpedal and return back the way you came, but you cannot deny that the cold is getting to you about as badly as it is her. Your body is terribly sore, then slowly goes limp as you try to return to that initial room, and eventually, your legs give out under you and you find yourself unable to muster the strength to get back on your feet. Your eyelids droop dangerously as the cold stone becomes strangely comfortable, and you embrace the coming sleep, hoping for all of this to turn out to be a bad dream.

Bad End.
