Back in the dorms, Fran tries to apologize to Nilka, but an angry Nilka wants nothing to do with her. The next morning Chef Ramsay explains the next challenge. Each team will be given 20 ingredients and must create in 30 minutes five dishes representing the five mother sauces: hollandaise, bechamel, veloute, tomato, and demi-glace. The catch? Each ingredient can only be used once.
The Blue Team starts working together, but over on the Red Team, a still bitter Nilka takes all the ingredients she wants without checking with her teammates and only focuses on her own dish. Since the Blue Team has an extra member, Autumn and Ed work together, and Ed explains during confessional that he much prefers having Autumn on the team over Scott. Fran and Nilka aren't getting along quite as well, and their bickering slows down their group. After the cooking time is up, Chef Ramsay introduces the guest judges for the "mother sauce" challenge -- his mother, Helen, and the mother of his children, his wife, Tana.
First up is tomato sauce. Fran's oyster fra diavolo beats out Salvatore's undercooked pasta dish, giving the Red Team a point. No one gets a point for the hollandaise dish, since Siobhan presents a Cornish hen dish that's actually one very undercooked pigeon and Tana doesn't care for Jay's duck dish. Next up is veloute. Ed's pan-roasted sea bass beats out Holli's halibut and gives the Blue Team a point. Though Chef Ramsay's mom loves both Nilka's pan-seared steak with mushroom demi-glace and Jason's strip steak with rosemary demi-glace, she gives the point to Nilka.
Finally, it's time for the bechamel dishes. Benjamin's John Dory beats out Scott's roasted duck breast, which means the score is all tied up. But because Jason had such an excellent dish, which would have beaten any other dish other than Nilka's, Chef Ramsay gives the win to the Blue Team. The defeated Red Team gets yet another punishment: They must deep-clean the kitchen and prep both kitchens for that night's dinner service, while the members of the Blue Team get treated to a fun afternoon at a British pub for darts and beer and then each gets a new set of cookware.
Back at "Hell's Kitchen," Scott complains that Nilka took all the good ingredients, while the team laments about losing yet again before suiting up for oven cleaning. Though none of the Red Team members enjoys the punishment, it's even worse for Siobhan, who breaks out in hives after suffering an allergic reaction to the oven cleaner.
After everything is cleaned and prepped and the Blue Team returns from their day of fun, Chef Ramsay gathers all the contestants together for an announcement: It's family night, which means the restaurant will also be offering a children's menu consisting of such kid-friendly items as fish sticks and fries. After the families arrive, the Red Kitchen gets its first ticket... and soon runs into its first bit of trouble when Chef Ramsay asks who's cooking the spaghetti. Turns out it's Siobhan's job, even though she had no idea that pasta falls under the garnish station.
The Blue Kitchen gets appetizers out to its diners, but Salvatore stumbles while making risotto and tries to cover up his mistake. Chef Ramsay flies off the handle when he catches Salvatore in a lie and soon discovers another risotto mistake -- this time in the Red Kitchen -- when Nilka forgets to put lobster in the risotto. The team gets another strike after as Fran doesn't live up to her reputation as last night's star and overcooks her scallops. After appetizers finally get out in the Red Kitchen, Scott messes up his Beef Wellington and is taken aside by Chef for a talking-to (or a yelling-at).
With no food leaving the Red Kitchen, Chef Ramsay hopes he'll have more success with the Blue Kitchen, but no such luck. He's missing a chicken, thanks to Jason, though Benjamin soon emerges as team leader and helps his group get back on track.
After more sub-par dishes come out of the Red Kitchen, Chef Ramsay is pushed to his limit and shuts it down. He kicks out the Red Team and completes their dinner service with the help of his sous chefs.
Upstairs, the Red Team members are humiliated and the ladies look to Scott as the scapegoat, but he insists it's their techniques that are the problem. Adding insult to injury, Chef Ramsay calls them all back down after service is over to clean up. He not only announces that they're the losers, but he also says that the night's service was the most disorganized ever.
After much debate and a string of accusations upstairs, the Red Team members are finally ready to announce their two nominees. Fran tells Chef Ramsay they've chosen Scott, who is a lot of talk but doesn't seem to produce anything. Fran says she's actually the second nominee, but believes it should be Siobhan instead. Nilka explains that Fran was nominated over Siobhan because Siobhan is more of team player.
When Chef Ramsay asks who the team's best chef is, Scott insists it's him, though Fran and Nilka vocally disagree. Chef Ramsay calls Fran, Siobhan, and Scott to the front and when Scott begins going on about how great of a chef he is, Chef Ramsay says he simply can't take any more and kicks him out. After Scott leaves, Chef Ramsay asks Benjamin to join the Red Team as its new team leader. Chef Ramsay then says if Scott could talk as well as he cooks, he'd be the winner of "Hell's Kitchen." Unfortunately, he can't.
