November 30th excerpt:
The entrance to Sam’s panic room remained intact and hidden, and it was Dean’s first place he wanted to check over. It needed to remain secured to the bottom of the underbelly while staying hidden, or it would lose its effectiveness.
Poking a finger in the entrance to make sure it was clear of any obstructions, Dean resolved to bug Sam later on to double check that no animals were roosting within. It would be a quick day’s work to pull off the tunnel and chase any birds or mice into the fields, and take care of any possible spiders.
With a grunt, Dean wiped down the outside of the pipe.
