Oz in Jeopardy!

I've started falling behind on these again, but now that my time is freed up a bit more I am cautiously optimistic that I can get caught up on these before the season ends in a few weeks, without becoming overwhelming. But I'm still a few months behind right now, as this is from the January 23, 2018 game. And when I saw the category Characters' Full Names in the Jeopardy! round, I had a sneaking suspicion that the clue below would turn up. Sure enough, for $600:

Alex, the challenger in the middle, rang in first and correctly responded, "Who is the Wizard of Oz?" He went on to do well, but came in second in the end to defending champion Rachel, who won again.
