February 3rd excerpt:

Sam charged, and this time Dean used his own smaller size to his advantage. Being the eldest, it smarted to have ended up the smaller of the two brothers, but it also meant he could dodge a lot faster than his bulky brother.

Dean dodged to the side, letting Sam blow past him. He lashed out with a foot, catching Sam’s arm with his hand and sending him to the ground. The end result was Dean holding Sam pinned to the ground, smirking at the annoyed hazel eyes below.
