In Sickness and in Health - S0.E2

In order to prove to her boss that she still has what it takes to be a great employee and that motherhood isn't getting in the way of her work, Jane does everything she can to hide the fact that she has the flu when the deadline to complete an important project is upon her. Meanwhile, a jealous Rosemary makes Horatio choose between being friends exclusively with her or a fellow nanny, and Emily's usually stoic husband, Jason, turns into her third child when he comes down with the flu.
