Near the end, the main character is forced to leave a few friends behind in order to get help. Only the help she goes to get doesn't seem concerned with her friends, and only wants to get them both out of them - and he only wanted to get *himself* out of there before, the only reason he's getting her out of there now is that she happened to show up. Going back might be death. He tells her this. Why do you want to throw your life away? Let's just go and leave them. Think of yourself. She ends up attacking him at this point (note: this is a very stupid move considering the people involved. think physically-average human female vs. musclebound berserker.) Naturally, he wins, pins her to the ground and holds a knife to her throat, and demands to know whether she'd be willing to die for the others. Because going back might be doing just that.
Keep in mind that this guy is nuts enough to take "yes, I would" as a signal to cut her throat and go back for the others alone.
And she ends up yelling that yes, she would.
Sometimes you just have to do something without thinking of the consequences because it's the Right Thing To Do, and if you thought about it, you might not do it. I've gotten more than one person wondering how on earth I could take my clothes off in an even semi-public place.
It's easy. You just do it.
Has anyone here ever been stuck in bed because they can't stop thinking about how to get up? You think "okay, the first step is to pull the covers off", and you try to do it, and then you realize you haven't actually done it, you've just thought about it. This cycle can repeat for quite a long time, believe me :) The trick to breaking it is to stop thinking about it and just do it. No, don't *think* about stopping thinking about it and doing it - actually *do* it.
It's the same kind of thing. Don't think about what it means. If you think too much you won't want to do it. Just shut off your brain and do it.
It's the same thing with pain tolerance. More than once working on the computer I've got my finger trapped somewhere jammed. And it hurts a lot, and my first instinct is to pull it out, and usually that works but sometimes it doesn't. And I could keep tugging on it, or I could just ignore the pain and think about it logically.
it's weird, doing that. It's like all your normal checks and balances are suddenly gone - that you're abandoning the part of your brain that makes sure you're still doing sane thing. But, then again, I've been abandoning that for quite a while, which is maybe why it's easier.
