He was proud. Fury actually looked proud which was an expression reserved for only a few and Lyra was one of those people now. There was a lot of chocolate.

"If you truly want to eat all the chocolate for breakfast, you can, but I think if you'd like to feel well for the rest of the day I'd limit it." Fury though was a believer in 'find out for yourself' lessons.
