Destiny gets compressed, you know, into just that small fraction of a second you have right in front of you at any one time. And there’s nothing romantic about keeping your head down to avoid getting shot, or trying to save a friend who’s been injured, or coming face to face with a creature who is as smart and mean and as terrified of dying as you are, and who wants to make sure that if someone is left on the ground there, it’s you and not it.
