i heard KK is still scheduled to make an appearance in this coming Monday's episode
i too was thinking she'll turn out to be a spy. but probably not. she has played a vital role in Chuck's personal life and will provide a twist to his character. this season has been heavy on Chuck transforming from the everyday, average nerd to someone who's a really good spy. and thats where they are revolving their story. that the weight of the Intersect, plus his eagerness to become a real spy has been transforming Chuck from the lovable nerd into a lying, double life, full-fledged spy, much to the dismay of Sarah and his unknowing friends and family. his double-life is already putting a strain on his relationship with Elle and Morgan
