Rounds: Here.
Disclaimer: I watched this episode when it first aired, and although I
did not recall any of it I cannot rule out memory being a factor.
Kylie Thompson is in the champion's seat tonight, and Richard asks where her enthusiasm for teaching comes from. Kylie says that it is her students, and seeing what they can achieve through what she teaches them. She tries to build a really good rapport with them, and this has resulted in her being nicknamed "Nanny K" (after her maiden name of Nankervis); she acquired that during her first year of teaching, and even now after marriage and a name change she still gets called that in the corridors.
Tonight's challenger is Lexi Wright, a student doing a bachelor of science with a focus on genetics and mathematics. She's still in first year, though, so it's a bit early to say how things will go. With respect to genetics, Lexi is interested in research and matters like the Human Genome Project.
The pattern of the game was set in the very first round, where Kylie's five-letter word was one better than Lexi's declaration. So it continued throughout the letters rounds: Kylie always was just one letter longer. Both contestants struggled with the numbers, failing to get within range for the first two numbers rounds, and then in the last numbers round Kylie again was one closer to the target. Neither could solve the conundrum, and Kylie won, 36 to 0.
