You and Sam were waiting for Dean to get back from getting burgers from the random fast food spot they had stopped at after a long hunt. Normally, Sam would talk after hunts; but tonight he was oddly silent.

Dean had tried to talk to him, but gave up before leaving go into the fast food spot. So, you turned around from the passenger seat to look towards Sam and he was looking away. You decided to try to get Sam to talk to you about what was on his mind and why he was silent tonight.
