Deandra "Sweet Dee" Reynolds
Deandra "Sweet Dee" Reynolds is Dennis' twin sister and the main bartender at Paddy's. Sweet Dee was definitely considered a loser in high school thanks in part to her back brace she had to wear back then. Sweet Dee failed out of U Penn, where she studied psychology. Now, she's mostly a failed actress and stuck as a bartender with her brother and his friends.
Charlie: what is your spaghetti policy?
Dee: Are you hearing this? He doesn't belong in a place like this.
Dee: Oh, you are being ridiculous. He's a professional football player.
Mac: No, look, I'm not talking about killing the guy. I'm just talking about going up there with a group of dudes and intimidate him, maybe break his arm.
Dee: You can't break Tom Brady's arm.
Mac: Oh yes, I can! No more Super Bowls for that pretty boy.
