After sending Cyndi home and putting Mary through to the finale, Chef Ramsay decides that Ja'Nel will compete for the grand prize. Calling Jon his "lone shining star" from the Blue Kitchen, Gordon asks him to stay in touch and lets him keep his jacket as he leaves Hell's Kitchen.
But the final two don't have much time to bask in the glory of the moment because they must pack their bags and get ready to board a private jet to Las Vegas. The women learn that for their final dinner service, they must prepare four stunning appetizers, four entr?es and two beautiful desserts.
When they arrive in Vegas, they meet their own personal concierge, who escorts them to their suite. They get right down to work putting their recipe ideas down on paper.
With less than 36 hours until the final dinner service, Mary and Ja'Nel get a visit from their sous chefs. Andi, who will work with Mary, and James, who is teamed with Ja'Nel, give them advice on their menu strengths and weaknesses.
Before they leave the city, they meet with Caesars Palace President Gary Selesner and last season's winner, Christina. She gives the two contestants valuable insight into how to tackle their last dinner service.
The competitors' return to Hell's Kitchen is brief, and then they are whisked off to Union Station in downtown Los Angeles. But rather than hopping a train, the contestants get a surprise visit from their families and discover that their next challenge will take place there - in front of a live audience.
As the clock begins to count down, Mary and Ja'Nel head off to the kitchen, where they have one hour to prepare five dishes. For their final challenge, they must each create one cold and one hot appetizer. They also have to cook three entr?es that feature fish, chicken and beef.
With the cooking complete, they meet Chef Sang Yoon, who critiques the cold apps. He calls Ja'Nel's deconstructed BLT beautiful. He says that Mary's ahi tuna tartare has a nice texture, but he thinks the sesame oil weighs the dish down. He gives the point to Ja'Nel.
Next up is Chef Homaru Cantu, who judges the hot apps. He prefers Mary's sweet potato gnocchi to Ja'Nel's mussels. And with that, the score is tied, one to one.
When Chef David Lefevre tastes the first entr?e, he chooses Ja'Nel's rainbow trout over Mary's Chilean sea bass. Ja'Nel takes the lead again. But Chef Douglas Keane gives Mary's seared chicken the point over Ja'Nel's oven-roasted breast.
With the score tied at two to two, Jeffrey Frederick from Caesars Entertainment declares that Ja'Nel's beef cheeks are better than Mary's New York strip. Having been awarded the final point, Ja'Nel wins the challenge and gets the advantage of choosing the first teammate for her brigade.
The two finalists are reunited with the former Hell's Kitchen contestants in front of the live audience. Ja'Nel picks Cyndi, Susan, Zach, Amanda and Ray. Mary selects Jon, Anthony, Nedra and Mike. She also ends up with Dan on her team, even though she had hoped to avoid working with him.
The competitors then receive letters from Chef Ramsay and discover that they can trade one member of each of their teams. In the end, Ja'Nel decides not to make a swap despite Mary's pleas to get rid of Dan. But after a night of strategizing with their groups, Ja'Nel decides to reconsider switching teammates. The outcome is revealed in the second half of the season finale of Hell's Kitchen.
