"Naja," Leia said, her tone becoming slightly sterner, "everyone has limits. Even with the help of your friends, you have limits. Even with the help of the train and all the people aboard it, there are still limits to what we can do. We can push those limits to a certain degree, but there's only so far that they can be pushed. Eventually, you reach a point where there is literally nothing more that can be done under the current circumstances."

"Refusing to acknowledge those limits doesn't make them go away. And trying to ignore them is dangerous, not only to yourself, but in general. We can argue 'what if's all we like with the benefit of hindsight, but the simple fact of the matter is, in any giving situation, the resources, skills, and knowledge you have available are limited, and that's all you have to work with at the time. You can't just pull more out of the ether. And sometimes? That's just not going to be enough. No matter how much you wish it were otherwise."
