that the brother relationship is what differentiates "NUMB3RS" from all the CSI's, L&O's, etc. out there. As for other brother shows. . .well, there was "Simon and Simon" back in the 80s.
I guess I'm more just *HOPING* the ex-girlfriend doesn't show up again. She would needlessly complicate the series.
Yes, Amita was in the pilot, this ep and one other one. I like her and hope they move her up to starring status next season. The show needs more than one women in the regular cast.
