Entertainment Weekly posted Supernatural stars cover EW to celebrate 300 episodes (and an epic reunion)

 

The discussion thread for episode 13 has more coverage.

 

The boys encounter another Alternate Universe, but this one is far, far better than the last one. John Winchester is alive! Dean is a wanted man? Sam is an Internet star? The boys get connect with their father again. Mary and John find each other. On top of all this we get to see what the people of Lebanon, Kansas think about those weird guys who live in the woods, in the (supposedly) secret bunker. What are you expecting from this episode? Are you looking forward to it? What surprises do you think we will see? Let us know in the comments or in the discussion thread for episode 13.
