"Head On" opens, but Variety tags Vince's performance in the film as lacklustre. To help fight off the cloud of the review, the boys head over to a Rolls Royce dealership, where Vince picks up a $320K Phantom, and then picks up some girls on the drive home.

Vince runs into Jimmy Kimmel, who immediately does his best to get Vince to commit to appearing on his show. Drama reveals he & Kimmel have a past history: that he disappeared & ignored him when Drama's career cooled off. Regardless, Vince decides to appear on the show.

The big day has arrived, and "Head On" is opening wide across the country, but Vince doesn't seem to be too concerned about going to see the film. Instead, he makes plans to spend the big night hanging out with his boys.

Vince is still dedicated to doing "Queens Boulevard" but Ari has yet to make that deal happen. Instead, the agent is pitching Vince on a myriad of other projects. Complicating matters is rival agent Josh Weinstein, who interjects himself into Vince's life.
