Sam was Manny Delgado's much older girlfriend in "Marco Polo". She was portrayed by Madison Iseman.
Jay and Gloria were worried about Manny hanging out with Sam, a new friend who was a senior while Manny was still a sophomore. They later realized that Manny's friend was actually a girl and she is also his girlfriend, which made Gloria worry even more. At Manny's High School football game, Jay caught Sam making out with what appeared to be her ex-boyfriend. He couldn't tell Manny because it would break his heart, and he couldn't tell Gloria either because she would break Sam, so he kept it all to himself until after the game. Back at home, Manny tried to sneak up to bed, but Jay caught him, inviting him to have a sip of scotch. Manny admitted that Sam dumped him. Actually, she was just using him to make her ex-boyfriend jealous. Manny couldn't believe his first girlfriend was just using him. Jay pointed out that of all the boys, Sam chose him to make her ex to get jealous and that should make him feel important because it meant he was at the same level as the other guy. But Manny was still heartbroken and he finally hugged Jay to feel better. Manny asked Jay if he could still have a sip of that scotch that he said. Jay told him yes, against Gloria's advice, and described it as a beautiful and full-bodied 18-year-old girl, which made Manny to remember Sam and cry even more.
