In the scene where Christopher confronts Tony about the accident, Tony is wearing a tan sportscoat, yellow shirt, dark pants, and brown shoes. At least one full day passes, as evident by the change in Tony's clothes to a short sleeved shirt. Later, when we see Tony in Dr. Melfi's office he's wearing the sportscoat outfit again.
When Adrianna is playing darts with Tony, her two darts that hit the board land in the bottom half and the middle of the board but when she gets them, she pulls the darts from the upper right part of the board.
When Christopher is telling Adriana about his toothache, he opens the door to his truck. In the truck mirror, for a split second, you can see a crew member wearing a gray hat, and another crew member standing next to him in a black hat.
Tony mentions to Adriana that his Escalade was totaled in the accident, "saving their lives". However, when enraged Christopher drives to the Bada Bing later and shoots holes in what he believes is Tony's car, its the same burgundy model Escalade. Its not likely that Tony's replacement vehicle would be the exact same car. (it's unclear if Chris was shooting someone else's car by mistake). After this episode, Tony drives first a white, then eventually a black model Escalade.
