BLOCK TO DE BOTTOM TO READ AS PER USUAL BBS.
The 100th episode that will be airing on April 15 is where one of the important characters makes a very critical decision.
”A very important character will sacrifice themselves in a suicide mission,” reveals exec producer Sera Gamble. “We definitely kept in mind that this was [an important] episode. We wanted to deliver something with real scope; it’s about the Archangel Michael."
WHAT THE FUUUUUUUUUUUUUUUUUDGE?
The Gambler also adds, "Crises will come to a head for Dean and Castiel. And you’ll see characters you never thought you’d see again.”
ORIGINAL AUSIELLO
It has been said before that the 100th episode will be focused around Dean's relationship with Michael and will possibly be a special longer-duration episode.
