We then check in with Jillian, who's hiking with Dan and Don. She wanted to take them out of the gym because it's clear that they're not engaged. They tell her that they're both extremely homesick, and this is more difficult than they've anticipated. Dan tells Jillian that he lost his son six years ago, when he was 24. His son had a drug problem, which he had been dealing with for about two years. Things were going well, and Dan talked to him every day. One day they didn't talk, and then his son was dead. Dan says it's the one great failure of his life. He thinks about his son every day, silently. Jillian asks why he thinks about him silently, and Dan says he doesn't want to hurt anybody else or make anybody else sad. Jillian tells him that grieving is cathartic. People want to feel something, and relate to other people. Dan isn't healing, she says, and his first step is not grieving silently anymore. Jillian tells us that she can't speak to what it would be like to lose a child, and could only imagine how terrible it would be. She worries for Dan that if he doesn't process this tragedy, it will ultimately take his life as well. Dan says that he'll be more in tune with his own personal needs and go from there, but frankly he isn't very convincing about it.

But forget about tragedy! We're now at the Four Seasons Hotel with celebrity chef Curtis Stone! Marci and Deni arrive and start beaming and hugging Curtis for just a moment too long. Deni says that she and Marci are friends and both moms, but now have to set friendship aside and compete. Curtis tells them to pay special attention as he prepares food with them, because at the end they'll have to tell him how many calories is in the food that they've prepared together. They'll be making roasted acorn squash with arugula, pomegranate, and a really light dressing. Curtis tells them to think of this time as not one of extreme dieting, but about developing a healthy relationship with food and learn how to experiment with new flavors and ingredients. Curtis fixes the dressing while talking about the various ingredients, and extols the values of arugula. With salads complete, Curtis moves on to the main course -- quinoa with pan-seared halibut in a parsley vinaigrette. The whole meal has no added salt, which seems like a miracle of blandness.
