Exactly! It's not like they didn't know weeks ago that AI would be on tonight...and as for the rumour that they changed it because of the pre-emptions in Chicago and Baltimore (for sports), that's bullshit, because they NEVER did that for Supernatural whenever it was pre-empted in those cities.

It's just ridiculous and disrespectful to the fans of the show, and really shows where the networks loyalty lies with it's own programing.
