We really take great pains to not retread things, executive producer Robert Singer tells EW.
Because that wouldnt be fun for the audience and its not fun for us.

Specifically, this season, Mary becomes a springboard toward interesting character growth for both of them.
Thats the character place, thats leaning heavily on whats come before, who these people are.
I wrote an episode a few seasons ago that applied cartoon logic toSupernatural, Dabb says.

That was literally from watching the Looney Tunes archives.
Weve done sitcoms on our show.
In the Changing Channels episode, we did our version ofGreys Anatomy.
Thats always really fun to do sure.
Once inspiration strikes, its about making sure the story fits within the world the shows established.
I find that those episodes are not the best.
