Input: Sybil Perez:  You have no idea what it 's like .
Catherine Willows: I saw her medical records . I looked at her x - rays . I know what that little girl suffered , what you put her through .
Sybil Perez: So you would let your child die and do nothing . Never . No , you 'd talk to doctors and research . And then you 'd find out that the national bone marrow registry ca n't help you 'cause your son is mixed race . And even if he was n't , there are n't enough donors . Out of _ four _ million , only 205000 are Latino . I did what I had to do .
Catherine Willows: You put one child over another .
Sybil Perez: I do n't expect you to understand . You do n't have kids .
Catherine Willows: Uh , I have a daughter .
Sybil Perez: So , what kind of mother are you ? When do you see her ? You work nights . You probably do n't even know where she half the time . Alicia 's life may not have been simple , but at least I knew her . Can you say the same ?
