The Cavanaughs - Season 1 Episode 10 A Chorus Malign

Two of Kit's fast and loose showgirl friends from the '70s, ""Legs"" Lawler and Crystal Line, plan a trip to Southie to stay with Kit for a night, before the three of them head out to Atlantic City together the next day for a ten-year reunion of former showgirls. But even that short amount of time is too long for Pop, who doesn't want Kit's trashy friends in his house, because he assumes they'll be a bad influence on Mary Margaret. Although Kit gets her way, that night after she goes to bed early, ""Legs"" and Crystal drink champagne with the awestruck Mary Margaret present, leave the bottle there, and Mary Margaret helps herself and gets smashed. Pop catches the aftermath of this, alerts Chuck, and they both demand that Kit throw the diabolical duo out. With Mary Margaret suffering a bad hangover, Kit does just that, and tells the girls she's not going to the reunion -- not because Pop said she couldn't, but because she realizes she's changed since coming home.
