Emily will pretty much immediately come to offer aid to the Kappa, and though she hates her promotion she'll offer to use it to negotiate more with businesses to get more supplies on hand as well as funds if she can manage it, pointing out how much to their benefit it is to do charity work and the boost to reputations.

Beyond that, she'll do what she can get her hands on, like serving in the food lines, but she'll also want to look at anyone sick or with injuries from the...everything that just happened, since that's her area of expertise. In short, what free time she has, she'll spend it on this.
