Plot hole: In episodes where Sam and Dean are required to perform spells/rituals at certain times, the issue not quite seen is that not all clocks are exactly in sync with each other, meaning that the clock they are using could be off by a few minutes especially if dealing with different time zones or time periods. (S07E12, Time After Time).
Continuity mistake: Elliot Ness and Dean are in his car waiting for the god of time. Elliot takes out his flask, takes a drink, offers some to Dean. Dean declines and Elliot puts the flask back in his pocket. The next shot Elliot is taking a drink again without pulling it back out of his pocket. (00:35:00)
Answer: Over the next few episodes, it is revealed that something is not quite right with Sam - that his soul is missing since he returned from Hell, and he does not feel any emotion or attachment to his brother.
