In the beginning the guards didn’t like each other but as the movie progresses they come more accustom to each other and they ‘become friends’ because they eventually hung out a little bit more and played rugby and they finally at the end of the movie they all finally rode in the same car as the other race and don’t even care, and that is really when apartheid ended.

Pinaar and Mandela at first didn’t really know each other and then they had tea together and then Nelson got to know him a bit more and they became pretty good friends.
