My thinking on that is, Kat wants to be taken seriously as Thomas's wife and head of household ... even though it was his party she could have made an impression by rising above it all ... like Cooper encouraged her to do ... she had an opportunity to change their minds and let TRav look like the crazy one while she was sane ... the look on her face ... she was so entitled and smug ... I think Whitney, as one Ex Producer - may have been clued in as to what would happen therefore he and mommy were not there ... despite fact that Thomas said to Kat that he wasn't inviting them because they were so unkind to her and he was being so considerate ... on second watching, and rewinding and rewinding I caught a laugh on his face as he was headed to the window ... set up plot ... on the preview of the upcoming show Kathryn telling him he needs to put Landon out of his life and he agrees ...
