I agree re Lois taking care of Clark. That was at the time they were still sort of happy-ish together, before the falling pillow put another chasm between them. It was also 12 parts ago (pt 82), which makes it over 30,000 words ago. I'm not saying it wasn't a good thing, but the situation was so extreme that if she hadn't done something, she would have looked like the biggest b*tch on the face of the earth.
Maybe the problem is I know some people who are selfish and unpleasant in normal, day-to-day interactions, but they come through like champs in a crisis because it's such a limited, one-time thing. Because of that, I don't tend to be overly impressed by good behavior in a crisis. Without congruent daily behavior, I'm inclined to believe that crisis behavior isn't what people are really like.
If you, OTOH, believe that a crisis reveals someone's true character, you're going to be much more impressed by crisis behavior than I am.
