Kevin is first up at the pass. He says he's been doing it anyway, in his cocksure way, but now he's going to do it better. Sous Chef Scott does some fish sabotage by swapping out two different kinds of seafood. Kevin catches it right away. Ariel sends overcooked lamb. Then sends lamb with the bones not properly cut off. Kevin suspects that she's doing it on purpose, but it looks like general incompetence to me. I'm not entirely sure she's talented enough to sabotage Kevin on purpose. She finally gets her meals out and Kevin gets a "good job" from Gordon.
Dave takes over the kitchen and he goes insane. He starts screaming at everyone, including Heather and chef Scott. Scott basically tells him to chill the hell out. And that helps a bit. But then He misses that they've swapped spinach and asparagus. Gordon pulls him aside and reminds him that he needs to taste things. Then not a minute later (at least in TV edited time), there's another sabotaged tuna dish that's wrong. Again, Gordon's not happy, but tells Dave to calm down. He might use a bit of profanity to get his point across, but it actually seems like he's being nice here. Then Dave finally notices that the next tuna is cold and that salt is missing in certain items, and he gets some good comments from Gordon.
Ariel's up, she seems loud enough, but she doesn't notice parsnip puree isn't mashed potatoes. And she tasted it. And she still didn't notice it. Distracted or stressed can be fixed, lack of palate can't. She does notice that Scott swapped the garnish on some fish, but then she yells out a ton of orders at once and Kevin is confused. Ariel blames Kevin, but Gordon has to step in and get things going properly. She manages to get through it, but not as smoothly as either of the guys.
Gordon says they all had their ups and downs, so it is hard for him to make a choice. He tells them he wants each of them to tell him who deserves to go home. He dispatches them so they have time to think about it. Dave feels lost about this. Ariel asks Kevin if he messed up the scallops on purpose. He doesn't cop to it, but Dave thinks maybe Kevin didn't try his hardest. I'd actually believe that Kevin was capable of sabotaging Ariel, but I just don't think he really cares enough. He seems pretty confident that he can beat both of them with one hand tied behind his back... oh wait, that's what Dave is doing. Still Kevin seems to think Ariel's incompetent enough on her own.
