A joke about the vast difference in their appetites is all but out before she remembers she's supposed to be starving (probably. She doesn't exactly know how things are right after Tyreese, only that it seems safe to assume 'not good'). It's not only her feelings about him that have to be kept quiet, it's everything, and she's not used to that anymore. Lying to him feels all the worse because she knows,now, how it hurts him when she does. Every word out of her mouth feels like that falling tree.

In the end, she doesn't say a thing about the prospect of eating. Lying is just too hard and she's out of practice, and this whole thing reminds her of why it was so frighteningly easy to convince herself that letting nothing in was preferable to being genuine. At least she's learned enough to put off making that decision right now, because she's not exactly thinking straight, and thankfully she got enough in the habit of second-guessing herself whenever she wants to run and hide.

Thankfully, almost everything she passes is a jumping off point for a subject change. In this case, a panel on one of the walls.

"Dare you to go press five of those buttons and see what happens." She offers a sidelong grin, obviously a little forced but it's not as if that should be anything new.
