I just started watching season 6 of Dexter. And it looks like the overall theme of the season is faith and religion. And Dexters lack of it. And in episode 4 "a horse of different color" I noticed something funny.
***Minor spoilers for episode 4***
In the hospital, after Dexter gets the good news, Mos Def says "I can´t prove that god exists, but you cant prove that he doesn´t" And when the camera pans in on Dexters face, you can clearly see in the background a tv that shows a commercial with people opening a jar.
The timing of the whole scene reminded me of this:
He claims he can prove god exists with a jar of peanutbutter.
Im not sure if it is just random, or something they put in there on purpose. I just thought it was a fun observation.
