Peter Facinelli’s smug and hilarious alter ego on Nurse Jackie has been around for six seasons strong but now Facinelli has decided to leave the series and the fans are getting a bit misty-eyed as Nurse Jackie debuts its seventh season Sunday on Showtime. Facinelli told E! News,”You know I’ve done it for six years. They’ve become like a family to me, Edie, Merritt. They are all such a great team of actors to work with. And I love the character, he is so much fun. But after six years I felt like, well, I’m contracted through seven, I kind of wanted to see what else is out there. And try a new character on for size and try something new.”
