I'm wondering exactly what Dean's reaction should be. I'm thinking he'll kinda have a plan already in mind-he'll start by pointing a 9mm at the guy and commanding him to sit down, if that doesn't work, he will shoot Marcus in the chest, and then if that doesn't work, headshot.<br/><br/>Also, I think Dean's glass is alarmed, so the police are likely already informed of an altercation in progress at the gun shop.
