I was amazed by that too! I wondered at first if he was related. There was also a moment later in the episode when Jimmy was standing in low light and for a second he looked JUST like Chuck. I wondered if that was somehow intentional or just my eyes playing tricks.

I get SO anxious in car-driving scenes when the camera is cropped in really close. Or when the driver is talking to the person in the passenger seat and feels the need to look directly at them while talking. Eyes on the road, buddy!
