Henrietta 'Hetty' Lange:  I imagine you 're still smarting from where the Chief of Police just ripped you a new one .
Marty Deeks: How 'd you know that ?
Henrietta 'Hetty' Lange: Because I just experienced something similar from my Director . It seems we need to co - ordinate our operations a little better . My boss wants to assign a liason officer from LAPD . And your boss thinks it 's a good idea .
Marty Deeks: Yeah . You guys do n't need a liason officer .
Henrietta 'Hetty' Lange: I agree . I told him we already have _ one _ .
