Kim and Murrow are both sick. It is Murrow's first cold, and they got sick on the same day and they're going through the exact same symptoms.
What's silly is that Murrow's nose bubbles (cute & gross) have reminded both of us that we used to call him Bubble Mouth … but neither of us can remember the exact context for that name? Did he make one big bubble with his mouth, or lots of tiny ones?
