As she lies dying, Fred's mind begins to give way. Nearing the end, she panics, stating that Feigenbaum, a stuffed rabbit named for mathematical physicist Mitchell Feigenbaum who studied chaos theory, should be there. When Wesley asks her who Feigenbaum is, Fred replies that she doesn't know. Cradling her in his arms, Wesley stays with Fred until the moment she dies, after which her body is taken over by Illyria. "Wesley, why can't I stay?" are Fred's last words.
