This is part of the special title card from episode 9.04 "Slumber Party"
Jared posted a video of it this morning.
In the left hand corner is a dedication to us… The fans…
"This is for the SPNFamily whose dedication and love drive us to continue creating this wonderful world. Keeping up the Family Business."
That’s for us. After everything.
This show… This is why I will always love this show. It's special. And we're damn lucky.
