Salvator "Sal" is Vince's cousin.
Sal is a sixteen year old who has recently gotten his learner's permit and is into comic books. He flirts by using his trademark, "Hey", which he uses on Grace, Karen and Jack.
During Thanksgiving at the D'Angelo's, Grace mistakes him for an older man and, after being pimped out by Karen, makes out with him in the garage. She later butts heads with Karen who also hooks up with Sal. Grace considers him to be "serious relationship material".
Dude, I just macked on two old ladies. — Queens For a Day
