From what I saw, the margin of victory for Nat and Kat was being able to answer the Marilyn Monroe movie question themselves and getting access to the internet easily. It was taxi karma once again, as Nat and Kat had a taxi driver with a cell phone who understood them! I thought it was hilarious that all taxi drivers at the Rose Bowl were apparently recent immigrants who barely understood English. Nat and Kat got through to someone on the Internet first and that made all the difference, even though they did not know the obvious answer to the first word puzzle question of Don Quixote. Getting off the plane first helped too. I wonder how Jill/Thomas allowed that to happen back in Seoul.
