It was only a week ago when U.S. women's gymnastics captain Aly Raisman bested her teammate, Jordyn Wieber, for a spot in the all-around competition.
The heavily-favored Wieber finished qualifying with one of the top scores in the competition.
Unfortunately for her, Raisman and fellow teammate Gabby Douglas were two of the few who posted higher scores than she did.
With only two gymnasts selected to represent each country, Wieber was left out of the finals.
With Wieber out of the picture, Raisman's shot at a medal looked as bright as it ever had, but the 18-year-old Massachusetts native tied for third in the all-around final.
What's even worse is that, based on further ruling, Raisman was denied a bronze medal and settled for a fourth-place finish.
It was a heartbreaking defeat for the American captain who shocked the world by beating Wieber, the "chosen one," just to make it to the all-around final.
Unfortunately for Raisman, her Cinderella story in the all-around competition didn't have a fairy tale ending.
Her failure to medal in the all-around competition was disappointing, but only made her more hungry for the event finals where she qualified first.
In Tuesday's floor exercise, Raisman will try to put her fourth-place finish behind her by dominating in her strongest event.
Do you think Aly Raisman will win the gold on Tuesday?
Raisman will have to compete against Wieber in the floor exercise, a matchup that will be one of the most highlighted of the Olympics.
It will be the veteran who wasn't supposed to have a shot at an individual gold, against the favorite who is more than ready to redeem herself after failing to meet expectations.
For Raisman, finishing the competition in her comfort zone will be very reassuring. Although Wieber will be gunning for gold, Raisman has dominated the event throughout the entire games.
Raisman has been hot and cold throughout these Olympics, but having the floor exercise as the final event puts the ball in her court in terms of winning a gold medal.
Wieber qualified in sixth position for the floor exercise, and beating out Raisman for the gold would be a satisfying ending for the 2011 World Champion.
It would be a Shakespearean ending in terms of revenge, but it will be difficult for Wieber to pull off the upset.
Just like she was hungry for revenge by failing to make the all-around final, Raisman will be just as determined to win a gold medal in her strongest event.
