Each puzzle header in this round shows a stack of flashcards. On top is a flashcard with a picture, and a word in English or Spanish. Translate the English words into Spanish and the Spanish words into English:
Spanish <=> English ---------------------------- ESCUELA => School Pared <= WALL Codo <= ELBOW OSCURO => Dark TABLA DE PLANCHAR => Ironing board CANTAR => Sing Erizo <= HEDGEHOG Nube <= CLOUD TALON => Heel ELEFANTE => Elephant Rana <= FROG
Sorting by number of cards in each stack and reading down the initials of the Spanish words gives EPCOT CENTER. Reading down the initials of the English words gives SWEDISH CHEF. So the seventh agent is the Swedish Chef, and he is located in Epcot Center.
