This was a return to the 'case of the week' and not one of the better episodes, but Fusco being taught how to appeal to the ladies was amusing. There was more fun with Reese and Finch being forced to adopt different personae. Reese learning not to shoot every suspect, and Finch playing the part of Egret.Finch recruits Fusco to stick close to the latest POI, a professional “wingman,” but learning how to approach women soon becomes the least of his worries. Meanwhile, Reese must find a way to play by the rules at his new day job as the Machine sends Finch and Root on a mysterious errand.
Fusco is now a full member of the team, but as he tells Reese, being a police officer is his job, not just a cover for his superhero identity. He wasn't only the comic foil here though and brings much to the team. We don't learn anything new, but the group dynamics are reinforced and the machine helps them to 'earn' enough money to cover their shortage of funds.
