Although its not shown in the screenshot, one of these girls is praising the casting of Liam as Gale and calls it perfect. Gale, who is supposed to have black hair and olive skin but was cast as a Caucasian Australian.
The girl on the top mentions Rue and President Snow as the other two casting choices that she dislikes, though it’s not included in the screenshot.
The girl on the bottom seems a teeny bit put off by Rue being black though. Funny how she picked up on the brown eyes and hair but missed the part about the dark brown skin that was in the SAME FREAKING SENTENCE.
