Sam was in a case, a demon case. He was looking around the area to see where you ran out. He saw you a in the corner of the alleyway and pointed his gun at you

“Don’t you dare…move a limb….if you don’t want a bullet through your skull….!!” he gritted his teeth and got closer to you. He knew the bullet wouldn’t exactly kill you but they had a curse that prevented you to move and you knew it

”Do.not.move…” he looked at you and texted his brother Dean to let him know that he was okay
