It's Thanksgiving, and the plan is for everyone to gather at Grams's house -- even Pacey, since his family eats later, presumably because everyone hopes his dad gets drunk enough to sleep through it? Gale is living in the Leery guest room while she, and somehow not Mitch, looks for an apartment; Dawson is suspicious of how pleasantly they're getting along. Joey is missing her poor dead mom today more than usual. Andie's plan is to make dinner for Jack and her dad, but then Joseph gets stuck in Chicago so they have to come to Grams's too so that Andie can be weird around Pacey. Only Jen is really having a great day and looking forward to fooling around with Pacey later, per their new FWB arrangement...so it's too bad for her when she opens her bedroom door and sees her mother Helen (Mel Harris!) standing there. What does Dawson do with his secret knowledge of Helen's past? How much does Joey bum everyone out with her orphan-osity? Do Jen and Pacey ever manage to bone??? We hope YOU will be our guest for our episode on "Guess Who's Coming To Dinner"!
