Audrey and Kim have never met. This should be awkward and feature some very bad acting.(On Kims part) Sorry to post this so late, but it doesn't look like anyone replied to you, and I just watched the episode, but my thought is they met at Jacks' "Funeral".
Someone mentioned that they could have met between seasons and another said that Kim and Chase lived in D.C.the time Jack and Audrey were there.So.....I guess Kim and Audrey have met!!LOL
