October 13th excerpt:

Sam turned in place, crossing his arms and arching an eyebrow to see Jacob just standing there with the salt. “Are you just gonna stand there and smell the daisies?” Sam asked testily. He mimed pouring salt in front of the door, shaking an invisible container in a line to demonstrate what he meant. “Salt in front of the door and windows, and do a line across the vent for good measure. We need to keep out what we can, considering how this case started.” 

December 10th excerpt:

If it wasn’t for the dire circumstances they were in, Dean’s face would have been painted with fascination at the chance to work with the tools Sherlock used on his cases. As it was, he set to his task with no wasted energy, carefully mopping up every drop of blood that speckled Sam’s knife. The murky gleam of red was soon replaced by the more familiar shine.

Dean’s small size made it simple to get the blood right on the tip of the paper. It was like working with oversized construction paper, and since the blade was made for Dean’s size, he didn’t have a problem.

A small mimic of Sherlock, Dean sat back on his heels, holding up the folded paper circle for Sherlock to take, its white surface marred by the ring of drying blood.
