She had only a slight lead going into Final Jeopardy today, after one of her opponents had hit both the daily doubles in the Double Jeopardy portion of the game, made big wagers, and then got them both.
Larissa risked a huge amount on final jeopardy, as usual, and hit it, so she remains as champion and is now likely the 3rd-highest money-winner ever on Jeopardy. Alex announced at the start today that she was in 4th and had a good chance of getting to 3rd, so I presume with her $40K winnings today she made it.
The final question was rather interesting, asking about a 1950's movie which starts at 10:30 A.M. and takes place practically in real time. 2 of the 3 nailed the answer--"High Noon".
