"When he defied the Capitol, they sent in a Capitol model that posed to be the victor that year. It was a girl named Tizon Jordania from District 7 who won them at age 16."
-Jackson talking about Haymitch and Tizon
Tizon Jordania was a Capitol model sent to pose as the victor of the 50th Games, as the victor that year was seen as making the Capitol look foolish. So, the Capitol tried their best covering the previous victor up and in no time, Tizon was said to be the winner that year instead of Haymitch. The Capitol pulled this off poorly, since people remembered Haymitch won instead of her. However, people were too scared to speak out about it.
