Not sure if things haven't re-populated after a change, but we seem to be missing overview and title from episode info:

http://api.themoviedb.org/3/tv/1418/season/1/episode/3?api_key=xxx

Gives:

{ air_date: "2007-10-08", episode_number: 3, name: "", overview: "", id: 64765, production_code: null, season_number: 1, still_path: null, vote_average: 0, vote_count: 0 }

Looks to be the same for a few series I've looked at
