Name the episode!

The boys are driving...well, Dean is driving. It is night. Dean calls Sam "bitch", Sam responds back a "Jerk" that's heavy on the "J" and then he looks down and smiles slow and sweet.

I need to know the episode so that I can cap it and hopefully make this icon that I want to make...I think my regular icon maker is busy at the moment.

Thanks!

ETA: I think it's Hunted. (2x10) ...not sure though, I'll have to pop in the episode later and check.
