Because if their world was destroyed, she thought she lost everyone. Lark, and her girls. All of her friends, and all the plants. The earth and her home. Briar was the one bit of hope she had to cling to, and suddenly he's granted her another. The question about food she ignores for the moment.

Rosethorn would eat, or not eat, just about anything right now so long as she gets to see Tris while she does.
