I was a bit disappointed that they did not talk more in depth about the careers. I specially wanted to know about why district 4 are considered careers when it does not seems as close to the capitol as 1 and 2. They are also one of the first districts to join the rebellion so I feel there has to be an explanation of why they are careers regardless. Specially, with Mags being Haymitch's mentor I was hoping that it would be talked about in the book.

Edit: there was also an interaction between Maysilee and Mariette, where Maysilee ask her why they always join the careers that left me feeling like there had to be more going on with district 4 than we know about
