Well Brad knows the girls 1000 times better than we do and he saw the "real" Em and ovbiously there was something about her that he fell in love with. Honestly we don't get to see the "real" Chantal, Emily heck we don't get to see the "real" any of these girls. It is an edited show and MF decides what little 1% of the girls personality we see. It's not the girls fault that we don't see who they really are it is MF's he takes the girls personality's and makes them into these one dimensional charachter that he wants us to see
