Changes

Between the time Elieen died and was revived, Sam has been practicing sign language for the first time since college. His improved use of sign language is seen in [[15.06 Golden Time]] and [[15.07 Last Call]]. In [[15.07 Last Call]], following her resurrection, Sam and Eileen spend more time together, including a night of many margaritas. As Dean leaves to go on a hunt, he teases Sam about his burgeoning relationship with Eileen, telling a protesting Sam to leave a sock on the door if needed.During a session of research (not a euphemism), they make moves towards a possible kiss when they are interrupted by Castiel's return.
