While Nasir will admire Carlos's perfect hair, knowing more than a thing or two about the importance of keeping hair full and luxurious even in the thick of battle, he will totally hate Carlos for being cooperative with the Capitol. So while he would have liked to extend an invitation to Team Hair, he'll have to hate him.

Which is my way of saying I'd love negative CR with these two, bonus points if they eventually get in on the rebellion together and it turns into positive CR over the long run.
