Fair enuff, racist comment, straight out...a choice well made.
Im not 100% entirely sure that charlie was as offeded as she looked,it was more to do with the fact that she has compitition there, and that was a perfect oppotunity to exploit it.
For example when she said the word, charlie reacted, after a little chat charlie said its fine, lets stop talking about it, then 2 seconds later would bring it up again, then she would say.."lets not talk about it anymore" then she would dig it up again.. making it worse and worse
