Little Paulie Germani is the nephew and right-hand of Soprano family Capo/Underboss Peter Paul "Paulie Walnuts" Gualtieri. Germani is an associate in the Moltisanti crew. When his uncle was arrested and imprisoned for a gun charge, Germani was his eyes and ears in New Jersey. He was responsible for repeating the joke that Ralph Cifaretto told the crew about Ginny Sack having a "95 pound mole removed from her ass". When the older Paulie told Johnny Sack about this he tried to have Ralphie killed. Germani also fed his uncle information about Tony Soprano's business that was passed on to Johnny Sack, causing problems for Tony. Germani also helped to uphold his uncle's interests in New Jersey taking part in a sit-down that awarded no-show and no-work jobs to the Gualtieri crew — Germani received a no-work carpenter job at the Esplanade construction site.
Later in Season 4, Germani was tasked with vandalizing Carmine Lupertazzi's restaurant when Tony and Carmine got into a dispute over the HUD scam. He was also responsible for intimidating Alan Sapinsly after Tony's separation caused him to withdraw from a contract to buy property from Sapinsly. Paulie and Benny Fazio used Tony's home entertainment system speakers on his boat to blast Dean Martin recordings at the Sapinsly home at all hours.
Germani regularly hangs out with Christopher Moltisanti and, if required, accompanies him on debt collections visits as extra muscle. Germani has taken a few knocks in the past, noticeably at a Columbus Day rally and after taking a joke too far with Eugene Pontecorvo at the Esplanade construction site, however he has shown staying power and may well make a decent soldier yet. In season 5, Little Paulie accompanied Chris when collecting a loan from writer J.T. Dolan. In season 6, Germani has been seen enjoying the private room at the Bada Bing with Benny and Chris. Paulie also attended Chris's belated bachelor party.
Germani helped his uncle organize the 2006 Feast of Saint Elzear and when his corner-cutting caused a ride to malfunction, Little Paulie was left to deal with the police.
In the Season 6, part II episode "Walk like a Man", Little Paulie is badly hurt after being pushed out of a window by Christopher Moltisanti over a feud between Paulie Walnuts and himself. He suffers 6 broken vertebrae. By the series finale however, he has begun to recover and has returned to his usual duties working for the Soprano Family, disguising himself as a police officer while searching fervently for Phil Leotardo.
