It's as if the producers are reinforcing some weird idea that all the blondes look alike or something...? I mean all these female characters being mentioned here, have quite distinct faces and physiques to me. I often get who might be implied when I hear "just like her" kind of lines in the show, but I never really get how is it really that one looks like an other. I try to see resemblances more on the grounds of personal history & character.
