Dean Winchester is a notorious hunter in the supernatural world. Every super natural creature knows to steer clear of the brothers. However… you had an entanglement with them a couple weeks ago and ended up helping Sam.

Due to that Sam has made you “Off limits.” Meaning Dean can’t kill you like he usually would. You two are constantly bickering and don’t like each other but as long as you don’t give him a reason to, he won’t put a stake through your heart because of Sam, despite wanting to.
