Mark and Jay head to one of their big-ass houses, where there is a banner sponsored by Altec. For every pound lost, Altec donates a dollar to nothing. Randomly, the banner features a Christmas tree and balloons. Maybe Altec is a leading manufacturer of Christmas trees and balloons? Mark and Jay enter to a big party and get to see their kids. Kathy, Jay's wife, notes with glee that Jay is so small. I wouldn't go that far, lady. Bernie also gets a big party -- perhaps even bigger than Mark and Jay's. Brittany gets a warm greeting from her family and friends, and her mom -- from whom Brittany got her awesome, shiny hair gene -- says that Brittany looks thinner and happier. Jenn leads Maggie into her party. Everybody loves everybody. Dan enters his house to raucous applause, and Jackie notes how great it was to see everybody's reaction to his 73-pound-thinner self. Kelly's family greets her wearing plastic leis. No wonder she cries all the time. Her boyfriend, Don of the moustache, is very proud of her. And then there's Roger, high-flying, adored. His wife, Paige, is super into him, and happy that for the first time she can put her arms all the way around him.

Paul's welcome home is also impressive, and he's greeted very warmly by his girlfriend Not-Kelly. She thinks that Paul was sexy before, but is even sexier now. I wonder how sexy she'll think he is when she sees him crying over Kelly all the livelong day? Paul says that his homecoming was the best thing to happen to him in 10-15 years. His brother, Rick, emotionally says that Paul will outlive their father. Rick is impressed by Paul's confidence and self-belief, but the most meaningful thing to him is hearing Paul say that he wants to live. Paul jokes with his mom that she can't make cupcakes, and adds that sprinkling bran on cheesecake doesn't make it good for you. Well, there goes my health regimen.

The family gatherings all have one thing in common: tons of food. We're talking danishes, ribs, cans of Crisco. Mark's son chows down on a big cinnamon bun. Like father, like son. Mark is worried about keeping up with his weight loss given all the distractions of home. His kids cry as he throws out the pastries. You'll thank him later when you're not a fatty, little girl. The next day, Mark cooks for his family. His wife, Erica, wonders if this will become a habit. Turns out that Erica has been losing weight too, and has gone down two sizes. Well done! She seems very nice, but I still expect to see all persons in Mark's life on Dr. Phil one day.
