Good quiz, however, you should consider putting the yellow box on because some of your answers are the same. Also, could you expand the acronyms to the actual names of the episodes, it was tedious to have to figure them out before answering the question.
The acronyms are used to make sure the boxes aren't too big / large. With only 9 possible episodes, I'm sure the time needed to work it out wasn't too bad, but I will add another minute to the timer and add the yellow box as requested
