Again, it was obviously a cross promotion because the scene of the demons beating Cass had gone to black for a commercial break before the clip was shown than immediately followed by that Halloween TV spot and Sam had specifically asked Nick, "What about Michael?" as in "Michael Myers", the villain of said movie. The season premiere was also advertised as being presented by Halloween later during the episode. I can only assume it must have been prematurely aired as I find it hard to believe the CW would intentionally reveal such a spoiler for then-currently airing new episode.
