Goodbye, London!

Plot:

As the journey in London comes to a wrap, the final four chefs welcome back the winner of Last Chance Kitchen. For this week's Quickfire, the chefs are joined by guest judge Sam Bompas, who challenges them to create a dish featuring jellies and molds. For their final Elimination Challenge in England, they're tasked with creating trompe-l'oeil dishes, where the plates must literally fool the eye and taste like something completely different than what they look like. Who will make it to the finals in Paris, and who will bid adieu?
