Kenny Shea - Season 4

Season 4

Lou is still dating the ex-nun and brags about the amount of wild sex he has been receiving. One scene shows the couple having sex in a church during mass. However, he asks for a "break", insisting that he can't handle so much and that it detracts from their personal relationship. He catches her sleeping with his cousin.

In spite of the conflict with his personality and his job as a firefighter, Lou is well-liked by his fellow firefighters, who often turn to him for advice. He also has a close friendship with Tommy, perhaps motivated by their failed marriages and struggles with alcoholism.
