Fresh Blood - S3-E7
Revealing mistake: Dean cuts himself near the beginning of the episode, however the blood begins to drip (spurt really) before the blade cuts into his arm.
Fresh Blood - S3-E7
Revealing mistake: Sam takes the SIM card out of his phone so it can't be tracked, but when he takes the back off his phone, there's no battery, and the SIM card is just lying in the back not attached to anything! Same for Dean's - he takes the back off and the card just falls right out, not secured in any way as it would be in a real phone.
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.
